About the role

About CircleCI Engineering CI/CD has been solved.
The interfaces that developers use to understand and trust that work don't exist yet.
At CircleCI, our guiding principles aren't posters on a wall.

Build AI-natively. AI is how we work. It's not a productivity layer on top of engineering, but the default starting point for how problems get approached and solved.
Own the full stack. Build features end-to-end in Go, React, and TypeScript. You don't hand off at a layer boundary. You own the outcome.
Obsess over craft. Reliability and responsiveness are design concerns, not afterthoughts. Care about how the interface holds up when stakes are high.
Champion observability. Use Honeycomb, Datadog, and Rollbar to understand and improve your systems. Operational data drives stability, not just incident response.
Full-stack depth. Strong React and TypeScript. Comfortable owning backend services in Go: API design, data modeling, service integration.
System design. You think about architecture, not just features. You make conscious tradeoffs and document your reasoning.
Production mindset. Latency, responsiveness, and reliability are design concerns. You're comfortable operating services in a distributed environment.
Build AI-natively.
System design.
You make conscious tradeoffs and document your reasoning.

You've stopped waiting for AI to mature and are already building with it, not as a productivity trick, but as a core part of how you think about problems.
CircleCI is the world's largest continuous integration/continuous delivery (CI/CD) platform, and the hub where code moves from idea to delivery.
