Location: San Francisco, CA
Type: Full-time, on-site
TLDR: we are seeing a surge in market demand as agents become real first-class citizens of the internet, and we are aggressively hiring in order to keep up. We're coming up with solutions in a problem space where no one in Silicon Valley knows the answer to either: how to build something agents want. If you like owning things 0 -> 1, lets chat.
AgentMail is building an API designed to give inboxes to AI agents and be the sole identity + communication provider. It isn't AI for your email, it's email for your AI.
We’re looking for a founding engineer with strong backend and infra instincts to help build the primitives agents will use to communicate, authenticate, and operate in the real world. This is a role for someone who likes systems work: APIs, distributed infrastructure, reliability, developer tooling.
Company highlights:
World-Class Team: Founded by a team of experts in their own respects(Quant, SWE, Private Equity), the team has top-tier talent from startups and big companies alike, with backgrounds from Optiver, NVIDIA, Amazon, Modern Treasury, KKR.
Hypergrowth: We’ve doubled our user count every 2 weeks since January, and don’t plan on slowing down any time soon. As agents will outnumber humans very soon, we see this multiple changing in the range of orders very soon.
Competitive-edge: We are the sole identity provider for agents. Just like you have a Gmail, agent’s will need an AgentMail.
Design APIs and abstractions that are intuitive for both humans and AI Agents
Build high-performant, low-latency systems with the idea that agents are the end-users in mind
Get your hands dirty by touching our core infrastructure that processes hundreds of thousands of emails per day.
Think creatively about being the bridge between cutting edge AI capabilities with something as primitive as email(an oxymoron we know)
Own projects end-to-end, from system design to production rollout
Write clear, maintainable code and strong technical documentation
Be the frontline for feedback from our customers - we’ll trust you to be our spokesperson
You want to solve problems end-to-end: every engineer owns a part of the product and needs to make decisions across the frontend, infrastructure, backend, and UX.
You have a high bar for quality: At a startup, speed is the only advantage we have over big-tech companies. But even more important is to care about your output and obsess about details.
You are a clear thinker and communicator: We have daily standups and weekly syncs in which we expect you to communicate tradeoffs, problems, and blockers directly.
You are highly technical: preferred you have prior experience shipping production software by real users as a software engineer at a tech company or startup. But hustlers are always appreciated.
Experience with cloud infrastructure, distributed systems, or developer tools

COMPANY OVERVIEW
AgentMail is building the communication and identity layer for AI agents.
Agents are starting to do real work, but they still lack basic infrastructure humans already have: persistent identity, reliable communication, permissions, memory, and a system of record. AgentMail gives every AI agent its own programmable inbox.
Developers use our API to create inboxes, send and receive email, manage threads, parse messages into structured data, route webhooks, attach domains, and build agents that can communicate across the internet.
We're backed by Y Combinator and have raised $6M led by General Catalyst, with support from the founders of Ramp, Supabase, and HubSpot, as well as Paul Graham.
We're early, moving fast, and building in a category without a playbook. If you want to help define core infrastructure for the agent era, we'd love to meet you.
TLDR
We're hiring a GTM Engineer to build the machine behind AgentMail's growth: the data pipeline, the outbound engine, and the source of truth the whole company runs on. This is a build-and-own role, not a support role.
WHAT YOU'LL DO
Own the growth data layer end to end: instrument the funnel, enrich every signup, and build the dashboards the company treats as the source of truth
Turn our best customers into ten more: lookalike modeling, automated outbound, LinkedIn plays, and surfacing champions and buyers inside companies already using us
Run experiments across the PLG engine (content, integrations, backlinks, paid) and double down on what moves signups
Connect the stack through APIs, webhooks, and automation so data moves cleanly between PostHog, our CRM, enrichment providers, and outbound tooling
Decide what tools we use and what gets kicked to the curb. You own the stack
Build AI-powered internal tools
Ship systems from prototype through rollout and adoption, then hold your ground. You built it, the team follows it
WHAT WE'RE LOOKING FOR
A technical foundation: CS, data science, or equivalent. You write real scripts in Python/TypeScript/SQL, wire APIs together, and are dangerous with Claude Code or Codex
You've seen a great growth motion up close, or you've been obsessively reverse-engineering how the best PLG companies grow
High agency in ambiguity: you call out what's broken, come with an opinion, and fix things without being asked
Low ego, high buy-in
Organized enough that the systems you build don't rot. Clean data is a discipline, not a feature
You want to help invent a market, not just run someone else's process
BONUS POINTS
Hands-on experience with tools like Clay, n8n, enrichment waterfalls, or sending infrastructure
PostHog fluency (we live in it)
You've shipped agentic workflows or internal AI tooling before
You've worked at or studied a technical PLG company up close
AgentMail is building the identity and communication infrastructure for AI agents, starting with email. We're a category-defining company and are looking for a Founding GTM & Operations Lead to design and run our growth playbook across all channels.
This role is critical to our function and owns how AgentMail grows. You will build the systems, narrative, and execution that turn early momentum into repeatable, compounding growth. Behind the growth, you'll also set up scalable automations and operating processes, tighten internal workflows, drive pricing and logistics projects, and build the dashboards we use to make decisions.
AgentMail has raised $6M from investors including General Catalyst, Y Combinator, Paul Graham (founder of YC), Karim Atiyeh (founder of Ramp), Paul Copplestone (founder of Supabase), and Dharmesh Shah (founder of HubSpot).
What you'll work on
Build and own the GTM playbook across all channels including PLG, content, community, outbound, partnerships, events, and launches
Design and run growth experiments end to end, then scale what compounds
Turn product usage and market signal into repeatable distribution loops
Define category narrative, positioning, and messaging so AgentMail becomes the default answer
Partner with product and engineering to bake growth into the product
Create repeatable launch motions for features, use cases, and integrations
Capture data across sales, product, and ops to build the dashboards that drive decisions
Build automations, internal tools, templates, and workflows that scale
Drive initiatives in pricing, logistics, vendor management, and ops quality
Define and test early sales motions with tight feedback loops, and run cross functional projects with fast turnaround
You're a fit if
You think in systems and growth loops, not one-off campaigns
You enjoy building playbooks from zero and pressure-testing them
You can run GTM across channels with high ownership
You are technical enough to build automations and develop a deep understanding of our product
You're Type A, process minded, and love making systems cleaner and faster
You can turn messy problems into crisp plans
You care about category creation, not just funnel optimization, and you want real ownership over how a company grows
Bonus points
Experience growing developer tools, infrastructure, or API-first products
Familiarity with PLG and sales-assisted growth
Strong intuition for content, community, and distribution
Experience with GTM systems and softwares: Zapier or similar automation tools (Make, n8n), Airtable, Notion, Google Sheets, CRM systems like HubSpot, basic dashboard tools, and comfort working with simple API style data like JSON
Previous operating, consulting, and investment banking experience is a plus.
Compensation: $110K to $175K, plus 0.2% to 0.5% equity.
PS. our bar for this position is ridiculously high. We are aiming to build one of the most distributed products of all time. If selected for an interview, expect growth discussions and case studies as part of our process.

AgentMail has raised $6M from investors including General Catalyst, Y Combinator, Paul Graham (founder of YC), Karim Atiyeh (founder of Ramp), Paul Copplestone (founder of Supabase), and Dharmesh Shah (founder of HubSpot).
