Infrastructure Engineer

Team of ~10, in‑person in SF. The role Flint 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: SOC2, threat modeling, or pen testing. You’ve built self‑service tooling that product engineers actually used.
