Team of ~10, in-person in SF.
The roleFlint runs background agents that make changes to real codebases and serves AI-generated pages at scale. That creates an infra problem most companies don't have: many agents editing code in parallel, and you have to coordinate, merge, and ship their work without it turning into chaos.
You'll own the systems that power all of it: cloud architecture, CI/CD, deployments, observability, and security. It's a 0-to-1 role: you'll inherit a scrappy setup and make it production-grade.
Recent work in this role: synchronizing and merging the git output of parallel background agents, building observability for agentic workloads, and hardening deployment pipelines.
What you'll own- The concurrency and coordination problems of running many background agents in parallel, the core hard problem of this role.
- Cloud infrastructure end-to-end: architecture, provisioning, CI/CD, deployments.
- Cutting latency and cost as we scale, without trading off reliability.
- Observability and incident response, so we know when things break before users do.
- Security across the stack and deployment pipelines.
- Making it easy for product engineers to deploy confidently and debug fast.
You're a fit if- You've scaled a product through real user growth and know what breaks, and when.
- You're strong with cloud (AWS or GCP), containers (Docker/Kubernetes), and IaC (Terraform or Pulumi).
- You think in systems, performance, reliability, and cost trade-offs come naturally.
- You can drop into infra you didn't build and make it better without a runbook.
Bonus- You've been through a startup growth phase.
- Security depth: SOC 2, threat modeling, or pen testing.
- You've built self-service tooling that product engineers actually used.
