Senior Software Engineer

CircleCI is reinventing CI/CD with AI agents that write code, trigger builds, interpret failures, and propose fixes. We're building the interfaces developers use to understand and trust that work. We hire for CircleCI, not a specific team; placement depends on where your strengths create the most leverage. You might own the CI pipeline experience, deploy and release tooling, notification infrastructure, monetization flows, AI agent surfaces, or the foundational web platform.

• Set technical direction, lead design discussions, write ADRs, and make calls.
• Invent new interfaces for autonomous pipelines and human judgment.
• Own the full stack end-to-end in Go, React, and TypeScript.
