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.
About Delivery Engineering
Delivery Engineering enables CircleCI engineers to deliver quickly, confidently, and securely. We provide the tools and resources that make standard patterns and best practices simple to adopt, and we reduce toil.
Our current focus is the agentic software development lifecycle: how changes are found, planned, built, reviewed, merged, and measured as AI agents take on more of the work. We evaluate the harnesses, repository patterns, skills, and agentic tooling available, decide what our teams should standardize on, and build and support the shared tooling other teams depend on.
We're a small, very senior team, and everyone on it shapes where we go. Every improvement we make compounds across the organization.
