Software Engineer

CircleCI is a continuous integration and continuous delivery platform reinventing software delivery through AI-native engineering. The Software Engineer will build full-stack features and interfaces for autonomous pipelines, own backend and frontend systems, and improve reliability, observability, and developer experience.

Responsibilities:

• 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
• 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
• 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
• Pick up slack. You'll notice gaps and close them — not because you were asked, but because that's the standard we hold ourselves to

Requirements:

• 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. You've built something real and put it in front of users
• 3+ years of production full-stack experience
• Strong React and TypeScript
• Comfortable owning backend services in Go: API design, data modeling, service integration
• You think about architecture, not just features
• You make conscious tradeoffs and document your reasoning
• Latency, responsiveness, and reliability are design concerns
• You're comfortable operating services in a distributed environment
