AI needs a new infrastructure layer. We're building it at Modal.
Every era of computing brought new workloads that previous infrastructure couldn't support: mainframes, databases, and the cloud. Each time, the company that rebuilt the layer underneath defined the decade. AI is no different, except it touches everything instead of one slice, and the window to build the layer underneath it is open right now.
Our customers include category-defining companies like Lovable, Ramp, Cognition, DoorDash, and Suno. They rely on Modal for instant GPU access, sub-second container starts, and native storage, so it's simple to serve low-latency inference, fine-tune models, and access production-ready sandboxes at scale.
We recently raised a $355M Series C at a $4.65B valuation, led by General Catalyst and Redpoint Ventures. We've crossed $300M+ ARR and grown fivefold since September.
Our team includes creators of popular open-source projects (e.g.,Seaborn,Luigi), academic researchers, international olympiad medalists, and experienced engineering and product leaders with decades of experience.
We are looking for strong engineers with experience and interest in designing, building, and maintaining the novel, high-performance systems that make up our serverless platform.
5+ years of experience writing high-quality production code
Experience building high-performance distributed systems at a large scale (the more battle scars, the better)
Strong cloud skills
Strong knowledge of low-level operating system foundations (Linux kernel, file systems, containers, etc.)
Experience with performance engineering (tell us a story of when you shaved off a few milliseconds!)
Ability to work in-person in our NYC or SF office.
Prior experience with Rust is nice to have, but not required.
Ability to participate in on-call rotation and respond to production incidents.

We're looking for engineers with deep AI/ML and low-level systems experience who want to build the best technical support experience in the world. This isn't a traditional support role — it's an engineering role where you happen to be closest to our customers.
You'll split your time roughly 50/50 between working directly with customers and shipping fixes, features, and automation that improve Modal for everyone. When you help a customer debug a training run, you'll also fix the underlying issue in the platform. When you notice ten customers hitting the same friction point, you'll build the tooling or automation that eliminates it entirely.
This role is for people who solve problems, not people who answer tickets. The problems you encounter are deeply technical and arise from running some of the most demanding AI workloads in the world. You'll be a member of our engineering team, contributing production code alongside the engineers building the core platform. The difference is that your roadmap is shaped by what you learn at the frontier of customer experience. You will:
Ship code that matters. Fix bugs, build features, and create automation that improves the experience for every Modal user — not just the one who reported the issue.
Work directly with customers. Help developers and ML engineers debug, optimize, and architect their workloads across Slack, email, and calls.
Build scalable systems. Design tooling, dashboards, and automated workflows that make support efficient at scale — delighting customers at the most important moments.
Close the feedback loop. Translate patterns you see in the field into concrete improvements — docs fixes, API changes, or new feature proposals.
Contribute to open source and technical content. Write examples, build demos, and publish content that helps the broader community succeed on Modal.
Accomplished in key areas. You bring depth in either low-level infrastructure or ML/AI, and you're not lost in the other.
Low-level infrastructure experience. Operating systems, file systems, networking, performance profiling, cluster management and distributed systems.
AI/ML engineering experience. Training models, optimizing inference, working with GPUs, or building ML infrastructure.
Automation mindset. Your instinct when you see a manual process is to eliminate it and you have the engineering background to make that happen.
Clear communicator. Can explain a systems issue to a customer, write a crisp bug report, and draft documentation, all while collaborating internally to ship improvements.

Most of the value of owning a model shows up at serving time. We're building a platform that covers the whole life of an LLM -- train it, deploy it, observe it -- and inference is where teams feel the difference every day. We already run elastic inference, sandboxes, distributed volumes, and multi-node training, and we control the infrastructure underneath, so the serving stack is ours to shape rather than something we resell.
You will do hands-on inference research at Modal, working with the research lead to pick high-impact bets and owning them end to end. The bets that matter most are the ones that move cost per token and tail latency on the workloads our customers actually run.
Own end-to-end inference research bets: speculative decoding, disaggregated prefill/decode, quantization (FP8, INT4), KV-cache and memory management, autoscaling for spiky serverless traffic, and whatever else the research agenda calls for.
Train custom speculators against real production traffic and feed what you learn back into target models -- acceptance length is the metric that decides the win.
Work directly with customers alongside our Forward Deployed Engineers to deploy and tune models, and bring what you learn back into the research.
Carry and expand collaborations with outside research labs, for example:
our work with ZLab on DFlash, a speculator design built on KV injection and blockwise parallel drafting
our work with SGLang on specdec and multimodal inference performance
our work on Flash Attention 4 kernels
Work with engineering to turn frontier serving techniques into products: primitives for disaggregation, fast weight refresh for models that keep training after deployment, observability for quality and latency in production, or even a next-generation inference engine.
Help shape the research agenda. None of the above is prescriptive; your work will help guide our future.
A research-leaning or systems background in LLM inference, with work you can point to.
Fluency in the LLM serving stack, from kernels and quantization up to schedulers and autoscaling.
A record of shipping research or systems that other people build on, whether in a lab or in industry.
The drive to independently take a research bet from idea to result, working in the open with the rest of the team.
Ability to work in-person, in our NYC or San Francisco office.

A PhD in computer science, machine learning, or a related field. Candidates with a master’s degree and significant research or industry experience will also be considered.
A demonstrated record of research accomplishments in reinforcement learning, machine learning, foundation models, or related fields.
Experience with large-scale training and inference infrastructure, including distributed systems and multi-node GPU clusters.
Experience developing, training, optimizing, or deploying state-of-the-art large-scale models.
First-author publications at leading venues such as NeurIPS, ICML, ICLR, CoRL, CVPR, UAI, JMLR, or TMLR.
A mission-driven mindset and a strong desire to translate research advances into meaningful product impact.
A collaborative spirit and the ability to work effectively across research and engineering teams.
AI needs a new infrastructure layer. We're building it at Modal.
Every era of computing brought new workloads that previous infrastructure couldn't support: mainframes, databases, and the cloud. Each time, the company that rebuilt the layer underneath defined the decade. AI is no different, except it touches everything instead of one slice, and the window to build the layer underneath it is open right now.
Our customers include category-defining companies like Lovable, Ramp, Cognition, DoorDash, and Suno. They rely on Modal for instant GPU access, sub-second container starts, and native storage, so it's simple to serve low-latency inference, fine-tune models, and access production-ready sandboxes at scale.
We recently raised a $355M Series C at a $4.65B valuation, led by General Catalyst and Redpoint Ventures. We've crossed $300M+ ARR and grown fivefold since September.
Our team includes creators of popular open-source projects (e.g.,Seaborn,Luigi), academic researchers, international olympiad medalists, and experienced engineering and product leaders with decades of experience.
Modal is the cloud platform built for AI. We're used by the world's leading AI labs, startups, and researchers to run compute-intensive workloads: training runs, inference, sandboxed code execution, and more.
We're hiring a Community Manager in SF to make Modal a fixture in the AI developer community. You'll bring developers together through meetups, hackathons, and events of our own, and build the kind of community that keeps showing up.
You know how to rinse and repeat the process, but always with a creative bend.
In this role, you will:
Co-host developer meetups with partners in our ecosystem. Find the right speakers, build the relationships, and run the events together. Prior examples: High Performance Inference for Open LLMs, Voice AI Builders Night, RL with Modal and Prime Intellect, FDE Happy Hour.
Sponsor hackathons that attract highly technical engineers and researchers in ML and AI Infra. For example: Autoresearch Hackathon with OpenAI, TreeHacks, HackIllinois.
Own and grow the webinar program: Partner with Modal engineers and FDEs to identify topics, speakers, promotion, and turning attendance into funnel growth.
Run creative events that break the standard. For example: eBPF documentary screening, Modal Art Show with Gray Area, etc.
Help community members run their own Modal events. Build the playbooks, templates, and support that let other people host meetups under the Modal banner, so events scale past what one person can run.
Turn events into content and campaigns. Work with Marketing so every event produces recaps, clips, talks, and stories that reach people who weren't in the room.
Own events end to end: venues, partners, speakers, logistics, promotion, day-of, and follow-up.
Track what's working: attendance, downstream signups and adoption and users within target accounts. Do more of what pulls and cut what doesn't.
A track record running events or building community. You've organized meetups, conferences, hackathons, or similar, and can point to specific ones that worked.
Plugged into the SF AI and developer scene, or able to get there fast. You know which companies, projects, and people are worth partnering with — and which trends and movements are worth jumping on, inside and outside of tech (e.g. agents, mahjong, board game nights).
Strong written and verbal communication. You'll represent Modal to developers, partners, and speakers, sometimes on stage.
Good judgment about what's worth doing. Not every event or sponsorship is worth the time, and you can tell the difference.
Organized and self-directed. This role runs many events and partner relationships at once.
Comfortable working in person in SF in a fast-paced startup environment.
Nice to have:
Existing relationships across the SF AI ecosystem: companies, open-source projects, DevRel teams, other community organizers.
Experience in developer marketing or DevRel.
Experience building a community-led or ambassador program.
Familiarity with Modal or the AI infrastructure space.
