About CircleCI Engineering

CI/CD has been solved. Now it's being reinvented. AI agents don't just run pipelines. They write code, trigger builds, interpret failures, and propose fixes. The interfaces that developers use to understand and trust that work don't exist yet. We're building them.

At CircleCI, our guiding principles aren't posters on a wall. We learn fast: we run experiments, accept failure, and scale what works. We think like the customer: every decision connects back to the developer sitting in front of a failing build at 2 am. We own the outcome: not just our slice of it, but the whole thing. If that's how you already work, you'll fit here.

Team-Agnostic Placement

We don't hire for a team. We hire for CircleCI. Where you land depends on where your strengths create the most leverage, and we figure that out together. You might own the CI pipeline experience, deploy and release tooling, notification infrastructure, monetization flows, AI agent surfaces, or the foundational web platform. The through line across all of it is the same: full-stack ownership, a high bar for craft, and work that directly shapes how tens of thousands of developers experience CircleCI every day.

What You'll Do

• 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 technical strategy for your domain. You decide when and how the architecture evolves, balancing technical debt against velocity. When a project spans teams, you're the one who breaks down the ambiguity and takes ownership of whether it lands.
• Invent new interfaces. Software delivery is being reinvented. Pipelines run autonomously, generate fixes, and surface results that need human judgment. The tools developers use to understand, trust, and act on that work don't exist yet. You'll define what they look like and establish the patterns the team builds on.
• Own the full stack, at scale. Build features end-to-end in Go, React, and TypeScript. Your ownership extends past your own code to the systems and teams around it.
• Connect engineering to the business. Partner directly with Product and Engineering Management to translate business goals into technical strategy. You understand the "why" behind the roadmap and use it to make tradeoffs.
• Champion observability. Drive monitoring and alerting strategy across your domain, not just your own services. Use Honeycomb, Datadog, and Rollbar to reduce noise and improve the org's ability to diagnose problems quickly.
• Mentor at scale. Mentor multiple engineers at once. Build the systems and documentation that transfer knowledge and remove single points of failure, not just your own.

What You'll Bring

• AI-native engineering practices. You use AI tools daily and can speak to what you've built, where they changed your approach, and where they fall short.
• A track record of shipping at scale. You've built and owned systems t

How CircleCI Uses AI in Hiring

At CircleCI, people make our hiring decisions. We use technology to support our recruiting team so they can spend more time on what matters most: getting to know you.

Where we may use AI

• Job descriptions and messaging : AI may help draft job descriptions and role-specific messaging so they are clear and accurate.
• Application review : For some roles, we use an AI tool to review applications, including resumes and application responses, against criteria our hiring team sets for the role. The tool generates a fit score and summary to help recruiters organize and prioritize applications.
• Interview notes : With advance notice, an AI note-taking tool may join interviews to record, transcribe, and summarize the conversation. This lets interviewers focus on talking with you. You will be told before each interview, and you may opt out at any stage by letting your recruiter know. If you opt out, the tool will not join, and your candidacy is not affected.
• Outreach : AI may help draft candidate outreach and scheduling messages, which our team reviews before sending.

Our commitment

AI does not make hiring decisions at CircleCI. Our recruiters and hiring teams review candidates and make every decision to advance or reject an application. No candidate is rejected based solely on an AI score. We have tools and processes in place to test for bias and to review how these tools perform, and we adjust our approach as AI technology and the laws that govern it change.

Your choices

You can ask for human-only review of your application, opt out of AI interview note-taking, request an accommodation, or ask questions about how we use AI. Contact recruiting@circleci.com . For how we handle your data, including retention, see our Privacy Policy.
