Cinder is the mission-critical infrastructure that keeps the world's most important digital platforms true to what they stand for. The internet has always been abused by bad actors, and AI is making it exponentially worse, driving fraud, abuse, and manipulation at a scale and speed no human team can fight alone. Cinder gives platforms one command center to fight back: to write and enforce policy, deploy AI agents against abuse in real time, investigate threats, file NCMEC reports, and prove their safety programs are working.
Our customers are some of the largest internet platforms in the world. The decisions made in our software directly determine what stays up, what comes down, and how users are treated.
We're a small, fast-moving team backed by Accel and Y Combinator. We care about being intentional, direct, and deeply focused on solving real customer problems.
You'd be building the infrastructure that some of the largest online communities in the world depend on to function. The problems aren't hypothetical: state-sponsored disinformation, CSAM reporting, coordinated abuse at scale. The software you build is used daily by the reviewers, investigators, and T&S leads making the calls that define what a platform stands for. This is an early-stage company with a mature product and real enterprise customers. You'll have outsized influence on architecture, product direction, and engineering culture.
This isn't a generic full-stack role. Here's what's actually on the roadmap right now and what you'd be contributing to:
AI agents that review content against customer policies, callable from within our durable workflow engine. We're moving from hardcoded LLM prompts to a configurable agent spec that customers can edit and deploy themselves.
A workflow engine built on Restate for durable execution. Engineers build new nodes that customers wire together to automate moderation pipelines, NCMEC reporting, enforcement actions, and more.
Review queue tooling: the core UI where moderators and investigators spend their day. You'd work on features like QA decision overrides, attribute-level labeling, forms, and skills-based routing.
Analytics and metrics dashboards that help T&S leads understand how their programs are performing, built with a React frontend backed by a Django/GraphQL API.
Two-way user communications: building integrations (Salesforce, Zendesk) so moderators can contact users and see conversation history without leaving Cinder.
Reliability at scale. Our customers process high volumes of content through review queues, workflows, and AI agents. You'd help define SLIs, improve pipeline throughput, and own oncall for systems where downtime means moderation stops.
5+ years building production software, with experience across the stack: Django or similar backend frameworks, React or similar on the frontend, relational databases, and message/event systems.
You've identified a customer problem yourself, not just been handed a ticket, and built an end-to-end solution for it. We don't operate with a traditional PM-led design approach at Cinder. Engineers participate in customer demos, hear feedback firsthand, and shape what gets built next.
Experience with high-throughput, data-intensive systems. Our platform ingests large volumes of entity data, events, and media from customer platforms. You should be comfortable reasoning about pipeline throughput, latency, and the tradeoffs that come with scale.
You have a real point of view on how AI tooling has changed the way you write code. We use it extensively and expect engineers to be fluent and opinionated, not just familiar.
End-to-end ownership. Even as AI code gen changes how frontend code gets written, you need to understand how the backend is designed to build something usable from start to finish. You'd own features from data model through API through UI.
Clear written communication. We're a distributed team with a concentration in NYC, and we work closely with customer-facing teams. You need to write clearly in PRs, Slack, and customer-facing documentation.
Experience in Trust & Safety or abuse prevention. Understanding how attackers exploit platforms gives you a head start.
Experience at a startup or early-stage company where you wore multiple hats and shipped fast with limited resources.
Familiarity with workflow/automation systems, policy engines, or case management tools.
Experience working directly with enterprise customers or in a customer-facing engineering role.
We're based in NYC and would relocate the right person for this role. We believe in working together in person and hold at least two all-company events per year. We offer health, vision & dental benefits, a 401(k) plan with employer matching, fully paid commuter benefits, and a fully stocked office with paid lunch and dinner.

Prototype at high fidelity to pressure-test flows and align engineering before build starts.
Contribute to and help maintain our design system as the product scales.
Take on design work beyond core product when it counts. This could include brand, GTM, decks, website, and marketing. We're a small design team, so we're looking for real appetite to proactively own broader design projects, not just tolerate them.
Sit in critique with our design lead. Give and take direct feedback, and help hold the bar on craft.
Strong visual and graphic design craft: the eye to judge quality, and the ability to produce clean work without leaning on AI tools.
6+ years designing software at senior to staff level, with real depth on technical products built for expert users.
Expert in Figma: wireframing, flows, prototyping, and production-grade delivery.
Fluent with AI coding agents (Cursor, Claude, Codex) for designing and prototyping, not just experimenting with them.
A high tolerance for ambiguity. You can create your own clarity and make calls without a finished PRD or research.
Proactive by default. You flag and fix design debt before anyone asks you to.
Comfortable talking to customers directly and turning what you hear into product opportunities.
Strong systems thinker. You see how changes in one part of the product affect the rest

Experience building B2B or enterprise SaaS with real depth: complex workflows, multiple personas, and heavy configuration. Our product is technically deep, but many of our users are domain experts rather than technical ones, so you know how to make powerful software feel simple and keep the interface approachable for technical and non-technical users alike.
Strong customer discovery skills. You can sit with a customer, find the real problem underneath what they're asking for, and turn it into product direction that scales.
Excellent prioritization. You can make and explain hard tradeoffs across strategic bets, customer commitments, quality, platform work, and near-term revenue.

Cinder gives platforms one command center to fight back: to write and enforce policy, deploy AI agents against abuse in real time, investigate threats, file NCMEC reports, and prove their safety programs are working.
Our customers are some of the largest internet platforms in the world. The decisions made in our software directly determine what stays up, what comes down, and how users are treated.
We're a small, fast-moving team backed by Accel and Y Combinator. We care about being intentional, direct, and deeply focused on solving real customer problems.
Cinder is expanding quickly, and we want to bring on an additional AI Engineer to partner with our current AI Engineers, Data Scientist, and Data Engineer. You'll build the ML systems that make Cinder faster, more efficient, and more accurate, turning the enormous volume of customer decision data we process into production models that directly shape customer outcomes.
We're looking for a builder. Someone who has taken models from messy data to production at scale, who reaches for a gradient-boosted tree before a transformer when that's the right call, and who has stood up ML infrastructure from scratch rather than inheriting it fully-built. What matters most is judgment: knowing the smallest, most efficient, most reliable model for the job, and understanding both ML methods and LLMs deeply enough to make that call yourself rather than defaulting to whichever one you know best. This role needs someone who cares as much about precision-recall tradeoffs, class imbalance, and serving latency as they do about model architecture.
Turn real-world customer data into something a model can actually learn from, then decide what model approach fits: a classical classifier when it wins on cost and latency, a fine-tuned LLM when the tradeoff is worth it, a third-party API as a bootstrap. You own the full path from data to decision, not just the model.
Improve our classification pipeline, confidence cascading, and detection strategies so we catch harmful content efficiently — balancing cost, latency, and accuracy deliberately.
Develop intelligent features that help moderators make decisions, organize platform content, and reveal patterns across our data.
Partner with Engineering to build out Cinder's in-house model training, hosting, and inference platform.
Design and build the evaluation and metrics infrastructure customers rely on, including how classifier scores and model outputs are calculated, stored, surfaced, and iterated on.
Partner with our Founding Data Scientist and AI Engineers to shape the agent evaluation architecture — measuring whether our agent fleet is making the right decisions with the right tools at the right cost.
Partner with our Data Engineer to shape the data infrastructure powering our ML systems, ensuring model training, feature pipelines, and production inference have the right data flowing at the right latency and scale.
Mentor teammates and raise the ML bar across the company as Cinder's ML capability matures.
5–8+ years of machine learning engineering experience on a small team, with a strong track record of shipping ML systems (gradient boosting, tree-based models, classifiers, embedding-based methods) to production.
You've taken a classification problem from messy, unlabeled, real-world data all the way to a model that shipped and served production traffic.
You understand LLMs well enough to make an informed, defensible call about when an LLM is worth its cost and latency versus a classic model.
Real, hands-on experience building classifiers under severe class imbalance, where the signal you care about is a small minority of the data
Thrived in environments where the ML infrastructure wasn't already built for you: you've stood up training pipelines, serving infrastructure, evaluation harnesses, and monitoring from scratch rather than inheriting a mature platform.
Startup or small/mid-size company experience where you owned meaningful scope and had to make pragmatic tradeoffs about what to build, what to buy, and what to defer.
Deep fluency with the fundamentals: thoughtful feature engineering, leak-aware train/test splits, metric selection on imbalanced data (precision/recall/F1/AUC over accuracy), cross-validation, and principled hyperparameter tuning.
Strong Python skills and hands-on experience with AI & ML frame works: (PyTorch, scikit-learn, langchain, XGBoost etc)
Solid MLOps foundation: CI/CD for ML, model versioning, experiment tracking, drift detection, and production monitoring. Bonus if you have experience with training, evaluating and serving models via Databricks
Experience designing inference systems with explicit latency and throughput targets, and independently making informed tradeoffs between model complexity, cost, and performance.
Experience with AWS and infrastructure-as-code (Terraform) is a plus.
We're based in NYC and will relocate for this role. We believe in working together in person and hold at least two all-company events per year. We offer health, vision & dental benefits, a 401(k) plan with employer matching, fully paid commuter benefits, and a fully stocked office with paid lunch and dinner.
","descriptionPlain":"ABOUT CINDER\n\nCinder is the mission-critical infrastructure that keeps the world's most important digital platforms true to what they stand for. The internet has always been abused by bad actors, and AI is making it exponentially worse, driving fraud, abuse, and manipulation at a scale and speed no human team can fight alone. Cinder gives platforms one command center to fight back: to write and enforce policy, deploy AI agents against abuse in real time, investigate threats, file NCMEC reports, and prove their safety programs are working.\n\nOur customers are some of the largest internet platforms in the world. The decisions made in our software directly determine what stays up, what comes down, and how users are treated.\n\nWe're a small, fast-moving team backed by Accel and Y Combinator. We care about being intentional, direct, and deeply focused on solving real customer problems.\n\n\n\n\nWHY THIS ROLE\n\nCinder is expanding quickly, and we want to bring on an additional AI Engineer to partner with our current AI Engineers, Data Scientist, and Data Engineer. You'll build the ML systems that make Cinder faster, more efficient, and more accurate, turning the enormous volume of customer decision data we process into production models that directly shape customer outcomes.\n\nWe're looking for a builder. Someone who has taken models from messy data to production at scale, who reaches for a gradient-boosted tree before a transformer when that's the right call, and who has stood up ML infrastructure from scratch rather than inheriting it fully-built. What matters most is judgment: knowing the smallest, most efficient, most reliable model for the job, and understanding both ML methods and LLMs deeply enough to make that call yourself rather than defaulting to whichever one you know best. This role needs someone who cares as much about precision-recall tradeoffs, class imbalance, and serving latency as they do about model architecture.\n\n\n\n\nWHAT YOU'LL DO\n\n - Turn real-world customer data into something a model can actually learn from, then decide what model approach fits: a classical classifier when it wins on cost and latency, a fine-tuned LLM when the tradeoff is worth it, a third-party API as a bootstrap. You own the full path from data to decision, not just the model.\n\n - Improve our classification pipeline, confidence cascading, and detection strategies so we catch harmful content efficiently — balancing cost, latency, and accuracy deliberately.\n\n - Develop intelligent features that help moderators make decisions, organize platform content, and reveal patterns across our data.\n\n - Partner with Engineering to build out Cinder's in-house model training, hosting, and inference platform.\n\n - Design and build the evaluation and metrics infrastructure customers rely on, including how classifier scores and model outputs are calculated, stored, surfaced, and iterated on.\n\n - Partner with our Founding Data Scientist and AI Engineers to shape the agent evaluation architecture — measuring whether our agent fleet is making the right decisions with the right tools at the right cost.\n\n - Partner with our Data Engineer to shape the data infrastructure powering our ML systems, ensuring model training, feature pipelines, and production inference have the right data flowing at the right latency and scale.\n\n - Mentor teammates and raise the ML bar across the company as Cinder's ML capability matures.\n \n \n\n\nWHAT WE’RE LOOKING FOR\n\n - 5–8+ years of machine learning engineering experience on a small team, with a strong track record of shipping ML systems (gradient boosting, tree-based models, classifiers, embedding-based methods) to production.\n\n - You've taken a classification problem from messy, unlabeled, real-world data all the way to a model that shipped and served production traffic.\n\n - You understand LLMs well enough to make an informed, defensible call about when an LLM is worth its cost and latency versus a classic model.\n\n - Real, hands-on experience building classifiers under severe class imbalance, where the signal you care about is a small minority of the data\n\n - Thrived in environments where the ML infrastructure wasn't already built for you: you've stood up training pipelines, serving infrastructure, evaluation harnesses, and monitoring from scratch rather than inheriting a mature platform.\n\n - Startup or small/mid-size company experience where you owned meaningful scope and had to make pragmatic tradeoffs about what to build, what to buy, and what to defer.\n\n - Deep fluency with the fundamentals: thoughtful feature engineering, leak-aware train/test splits, metric selection on imbalanced data (precision/recall/F1/AUC over accuracy), cross-validation, and principled hyperparameter tuning.\n\n - Strong Python skills and hands-on experience with AI & ML frame works: (PyTorch, scikit-learn, langchain, XGBoost etc)\n\n - Solid MLOps foundation: CI/CD for ML, model versioning, experiment tracking, drift detection, and production monitoring.

Our customers are some of the largest internet platforms in the world. The decisions made in our software directly determine what stays up, what comes down, and how users are treated.
We're a small, fast-moving team backed by Accel and Y Combinator. We care about being intentional, direct, and deeply focused on solving real customer problems.
Cinder’s Core Infrastructure team builds the platform and infrastructure that judges the safety of much of the user-generated content on the internet. This journey requires extreme focus and ruthless prioritization. As Cinder has grown, Core Infra has become responsible for the critical pieces that underpin workstreams across the product, without a dedicated leader to organize that work. We have a small, senior team doing high-leverage work, and we need a capable people manager to ensure that effort is aimed at the right things, coordinated cleanly with the rest of the company, and never wasted on collisions or unclear ownership.
This is a people and coordination role at its core. Your job is to take a group of strong, self-directed engineers and make sure they're working on the most important things, that those priorities are clear, and that the rest of the company knows how to work with the team. You'll need enough technical depth to earn the respect of senior engineers and hold your own in architecture discussions; the team is strong enough to largely run its own execution. You'll report to our Head of Engineering and have real influence on how we build out engineering leadership as the org scales.
You'll own the health, direction, and delivery of the Core Infra team. The team owns the systems the rest of engineering builds on, including the graph service, CI/CD, and core developer tooling. It's a small team that leans senior, and its work is a genuine competitive advantage for Cinder. In practice that means:
Setting clear priorities and a roadmap your team understands. Engineers should know what they're working on, why it matters to the business, and what we're choosing not to do. You'll bring the business context behind the work and translate it into focused execution.
Owning the interface between Core Infra and the rest of the company. You'll be the clear point of contact for other teams, run the intake process for work coming into Core Infra, and make sure requests are triaged, routed, and prioritized transparently rather than landing through back-channels. You’ll be the default liaison to GTM, FDE, CX and other cross-functional partners, and pick up technical work alongside your team when it helps, without becoming a blocker.
Raising the bar on team-level execution. All Engineering Managers at Cinder are focused on advancing both velocity and quality. You will implement the right level of process to keep a growing team moving fast while remaining responsive to needs of the broader engineering organization. We want to deliver robust features with clear ownership and vision - the kind of feature all of us love to see when we’re oncall.
Coaching and developing engineers. You’ll set clear expectations against role and provide direct, constructive feedback promptly and empathetically. People should always know how they're progressing and where they need to grow.
Driving operational rigor proactively. Helping define SLIs/SLOs for your team's systems and getting ahead of reliability and tech-debt problems to get ahead of incidents.
This role is about organizing and leading a senior team and owning its priorities and coordination, not about being its lead architect or top individual contributor. The team owns its technical execution; you own making sure it's aimed correctly and running smoothly.
8+ years building production software with at least 4 years in a startup environment, managing platform engineers directly. You've owned a team's delivery, not just your own, and you've grown ICs into stronger engineers.
Deep familiarity with high-throughput, data-intensive systems, workflow/automation engines, or AI-powered platforms in production, with experience managing full stack engineers
A track record of driving a high-performing team: clear priorities and sufficient process to drive both velocity and quality, grounded in metrics.
Technical credibility with a senior team. You can lead architecture and trade-off discussions, review work, and earn the respect of staff-level engineers. We use AI tooling extensively and expect you to be fluent and opinionated about how it changes the way teams build.
Experience setting roadmaps and priorities in an ambiguous, fast-moving environment, and the judgment to decide what to deprioritize.
A real point of view on what high-performing engineering teams look like and how to measure them, with experience driving reliability, quality, or operational metrics..
You give direct, constructive feedback as a matter of course, and you deliver it in a way people can act on.
Clear written communication. While our company is concentrated in our NYC headquarters, this team is distributed across London and the east coast of the US. You write clearly in PRs, Slack, planning docs, and cross-functional updates.
Experience in Trust & Safety or abuse prevention. Understanding how attackers exploit platforms gives you a head start.
Experience operating at the Product ↔ Engineering boundary, or in a customer-facing engineering capacity.
We're based in NYC and would relocate the right person for this role. We believe in working together in person and hold at least two all-company events per year.

We're a small, fast-moving team backed by Accel and Y Combinator. We care about being intentional, direct, and deeply focused on solving real customer problems.
Once a deal closes, you're the technical owner on the ground. You're the escalation point for the customer, working closely with their CSM and Agent Product Manager (agent PM), and the first line of engineering defense when something isn't working the way they expect.
For some customers, \"close\" means embedded. You're effectively part of their engineering team, in their Slack, on their calls, building alongside them. The platforms you'd be embedded with have hundreds of millions of users between them. When you fix something, it's not hypothetical. It's live, that day.
Shape and prove the solution. Work directly with customers to understand their problems, identify the right use cases, and build proofs of concept that demonstrate value and de-risk the path to production.
Own deployments end to end. Take the technical work from scoping and system design through implementation, rollout, and adoption — partnering with the CSM while owning the engineering plan.
Build the last mile. Connect Cinder to each customer’s stack through APIs, webhooks, data pipelines, custom workflows, and production-quality code where configuration isn’t enough.
Enable customer teams. Run technical workshops, document what you build, and give customers the knowledge and tools to operate successfully without us in the room.
Turn fieldwork into product leverage. Solve issues in the systems you ship, identify patterns across customers, and turn those lessons into reusable tools and improvements to the core product. Own on-call for customers when system downtime means moderation stops.
4-8 years as a software engineer, solutions engineer, or in a similar role in a fast-paced, high-growth environment.
Solid Python fundamentals. You can read, debug, and extend backend code without hand-holding. Comfortability with SQL, Typescript, React, and GraphQL.
Real experience owning implementation, not just scoping it. You've configured or customized a product for a specific customer and shipped something that changed what that customer could actually do.
You are exceptionally comfortable with ambiguity and repeatedly take initiative — you thrive when dropped into unfamiliar situations, learning quickly, and finding ways to deliver value.
No degree requirement. We care about what you can build, not where you learned to build it. Bootcamp grads are welcome.
Understanding of trust & safety or safety operations, either firsthand (you've worked in it) or through a specialized background — a T&S-focused master's, for example — that gives you real fluency, not just familiarity.
Consulting experience where you turned a client's ambiguous ask into a working solution.
Familiarity with React Query or Strawberry specifically.
Experience being embedded with a customer or client team, rather than working at arm's length through tickets.
Our team is based in London and we believe that in-person collaboration is important. We offer medical and dental insurance benefits through Allianz Global. We hold at least two all-company events per year. We offer paid lunch when our team is in-person.
","descriptionPlain":"ABOUT CINDER\n\nCinder is the mission-critical infrastructure that keeps the world's most important digital platforms true to what they stand for. The internet has always been abused by bad actors, and AI is making it exponentially worse, driving fraud, abuse, and manipulation at a scale and speed no human team can fight alone. Cinder gives platforms one command center to fight back: to write and enforce policy, deploy AI agents against abuse in real time, investigate threats, file NCMEC reports, and prove their safety programs are working.\n\nOur customers are some of the largest internet platforms in the world. The decisions made in our software directly determine what stays up, what comes down, and how users are treated.\n\nWe're a small, fast-moving team backed by Accel and Y Combinator. We care about being intentional, direct, and deeply focused on solving real customer problems.\n\n\n\n\nWHY THIS ROLE\n\nOnce a deal closes, you're the technical owner on the ground. You're the escalation point for the customer, working closely with their CSM and Agent Product Manager (agent PM), and the first line of engineering defense when something isn't working the way they expect.\n\nFor some customers, \"close\" means embedded. You're effectively part of their engineering team, in their Slack, on their calls, building alongside them. The platforms you'd be embedded with have hundreds of millions of users between them. When you fix something, it's not hypothetical. It's live, that day.\n\n\n\n\nWHAT YOU'D ACTUALLY WORK ON\n\n - Shape and prove the solution. Work directly with customers to understand their problems, identify the right use cases, and build proofs of concept that demonstrate value and de-risk the path to production.\n\n - Own deployments end to end. Take the technical work from scoping and system design through implementation, rollout, and adoption — partnering with the CSM while owning the engineering plan.\n\n - Build the last mile. Connect Cinder to each customer’s stack through APIs, webhooks, data pipelines, custom workflows, and production-quality code where configuration isn’t enough.\n\n - Enable customer teams. Run technical workshops, document what you build, and give customers the knowledge and tools to operate successfully without us in the room.\n\n - Turn fieldwork into product leverage. Solve issues in the systems you ship, identify patterns across customers, and turn those lessons into reusable tools and improvements to the core product. Own on-call for customers when system downtime means moderation stops.\n \n \n\n\nWHAT WE'RE LOOKING FOR\n\n - 4-8 years as a software engineer, solutions engineer, or in a similar role in a fast-paced, high-growth environment.\n\n - Solid Python fundamentals. You can read, debug, and extend backend code without hand-holding. Comfortability with SQL, Typescript, React, and GraphQL.\n\n - Real experience owning implementation, not just scoping it. You've configured or customized a product for a specific customer and shipped something that changed what that customer could actually do.\n\n - You are exceptionally comfortable with ambiguity and repeatedly take initiative — you thrive when dropped into unfamiliar situations, learning quickly, and finding ways to deliver value.\n\n - No degree requirement.

Our customers are some of the largest internet platforms in the world. The decisions made in our software directly determine what stays up, what comes down, and how users are treated.
We're a small, fast-moving team backed by Accel and Y Combinator. We care about being intentional, direct, and deeply focused on solving real customer problems.
Most companies building with generative AI don't know yet that they have a trust and safety problem. They will soon, and Cinder is the infrastructure they'll run on when they do. Right now, that story lives only with our current customers, and getting it in front of the right people before they know they need it is the job.
You'll work closely with our existing marketing team to make that happen. The positioning and content foundation already exist, and your job is figuring out how to get it in front of a market that doesn't buy the way traditional enterprise software buyers do. Expect to be creating, shipping and measuring your own work, as well as fine-tuning the strategy as the motion proves out. The conventional B2B demand gen playbook only gets you partway there, so we want someone with a real point of view on how to reach this market.
This role reports to our Head of Sales.
Build marketing-sourced pipeline: set the target with our Head of Sales, and have real latitude on channel mix and strategy to hit it
Take our existing positioning on AI red teaming, agentic moderation, and content integrity and turn it into a story that lands with a generative AI buyer specifically, which is different from how it lands with a marketplace or social platform. You'll work with our Founding Marketer and Sales team on the core narrative and own how it shows up on the website and in what sales says in a deal
Increase demand-gen performance of our customer case studies and stories (written, video, sales deck). One of our current case studies is already one of our best-performing assets, and we want more at that bar, good enough that customers ask to be featured rather than the other way around
Take our content and thought leadership engine — blog, newsletter, ghostwriting support for our founders — and turn it into an explosive growth channel: consistent cadence, sharper distribution, and original research or benchmarks that set Cinder apart. You'll brief and edit copy with your team on what the core narrative should be
Support events strategy as a demand-gen engine. You’ll determine which events Cinder should attend, sponsor, skip, and how we show up both at and around the event.
Spot and act on relevant news and industry moments quickly, building timely campaigns that capture attention while it's there
Own campaign measurement and reporting: attribution, lead scoring, and inbound reporting that show where pipeline comes from and where the next dollar should go
Partner with sales on lead scoring, handoff, and follow-up so marketing-sourced leads actually convert
You've built demand generation for an AI product specifically, not just a general tech or B2B product. This is the requirement we care about most. Cinder is an AI company selling an AI product to companies building with AI, and you should be able to hold a real conversation about how models and agents behave, why evals matter, and where these systems break, because with this audience, that fluency is the marketing.
4+ years in growth marketing or B2B demand generation, and you built from zero: the first marketing or demand gen hire somewhere, with no existing pipeline, playbook, or established program to inherit.
A track record of owning a pipeline number: what you targeted, what you hit, and what you missed
You've built demand in a category where the downside of failure is existential (cybersecurity, identity and authentication, fintech risk, regtech, or similar). You know how to write about serious risk accurately, and how buyers behave when the downside is a breach or an incident
You care about the internet being a safer place. This is more than a job to you, and it shows in your work
Strong judgment on content, positioning, and messaging. You'll brief and edit copy written by others (or drafted with AI) rather than write all long-form copy yourself, but you know the difference between good and generic
Comfortable in a CRM and marketing automation stack, and able to build your own reporting rather than wait on someone else for it
A builder's mentality: low ego, high ownership, comfortable defining your own strategy and workflows in a small team
Experience marketing an enterprise/B2B product into consumer-facing companies (social platforms, marketplaces, dating apps, gaming, fintech apps, or B2C-facing AI products)
Experience with ABM or intent-data tools
Field marketing at conference scale
You've built a research report, index, or open benchmark that became a demand asset
Comfortable flexing into other marketing specializations (ABM, product marketing, SEO)
We're based in NYC and would relocate the right person for this role. We believe in working together in person 4-5 days a week and hold at least two all-company events per year. We offer health, vision & dental benefits, a 401(k) plan with employer matching, fully paid commuter benefits, and a fully stocked office with paid lunch and dinner.
