About the Role
As a Staff AI Platform Engineer, you will own the developer experience, platform infrastructure, and reliability of our AI-native platform. You will shape the foundations that enable our engineering team and AI agents to build, test, review, and deploy features safely and at speed. This role offers high leverage, multiplying the output of every engineer and agent.
Responsibilities
- Own our developer experience and factory — the build, test, deploy, and local-dev loop that lets engineers and agents ship fast, with confidence.
- Build agent-safe environments — sandboxes, guardrails, and context that let agents investigate issues, build, review work and ship autonomously.
- Own reliability, end-to-end — SLOs, on-call health, observability, incident response and prevention.
- Own our cloud infrastructure and cost — AWS, scalability, and spend visibility for the org.
- Design and evolve platform capabilities that work across multiple teams and support multiple engineers and agents contributing code.
- Remove systemic bottlenecks — every fix compounds across engineering, not just your own team.
- Share platform expertise openly, educate the wider engineering team, and create clear paths for others to contribute to infrastructure and platform changes.
Requirements
- You push the frontier of what coding agents can do, and have built the environments, guardrails, evaluation frameworks and context that allows agents to build safely at speed for others, not just for yourself.
- You prioritise platform work by its downstream impact on shipping customer outcomes, not by gold-plating infrastructure.
- You can talk about who used what you built and why it mattered.
- You've owned developer experience, CI/CD, build/deploy tooling and cloud infrastructure for a shipping team, and you think in leverage: your proudest work made everyone else faster.
- You’ve owned SLOs, on-call health, observability, and incident response directly without a separate SRE team to rely on.
- You’ve improved teams beyond your own; educating, unblocking others and setting standards that other people have adopted.
- You raise the standard for people around you, you're comfortable with ambiguity and pace, and you believe a smaller AI-native team can out-build a larger, traditional one.
- Experience in our exact stack is not required — what matters more is how fast you can pick up a new one, and how deeply you already use AI coding agents as part of your daily workflow.
