Staff Software Engineer

CircleCI is a continuous integration and continuous delivery platform that is reinventing software delivery with AI-native tools and interfaces. The Staff Software Engineer will own technical strategy, design and build full-stack systems at scale, define new developer interfaces, drive observability, connect engineering decisions to business goals, and mentor engineers.

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
• 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

Requirements:

• You use AI tools daily and can speak to what you've built, where they changed your approach, and where they fall short
• 8+ years of production full-stack experience, with a history of taking accountability for outcomes
• Strong across the stack — React and TypeScript on the frontend, Go on the backend, owning API design, data modeling, and service integration
• You own architecture decisions that span multiple systems and teams. You make the tradeoff calls, document the reasoning, and are the person others escalate to when the answer isn't obvious
• You understand how your domain connects to the broader business, and you use that context to guide technical decisions, not just implement them
• You mentor engineers, give direct feedback on technical direction, and raise the quality bar across teams through how you engage in reviews and design discussions, not just what you ship
