Frontend Senior Software Engineer building complex UI systems and tools for Kabam’s multiplayer games. Supporting performance, scalability, and artist and designer workflows on an unannounced project.
About the role
- Senior Software Engineer at CircleCI developing AI-driven solutions for CI/CD processes. Leading design discussions, building features, and mentoring engineers in a full-stack environment.
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.
- You define the approach others build from. When the problem is complex or the answer isn't obvious, you're the person who leads the design discussion, writes the ADR, and makes the call.
- Software delivery is being reinvented. You'll define what they look like and establish the patterns the team builds on.
- Build features end-to-end in Go, React, and TypeScript. You don't hand off at a layer boundary. You own the outcome.
- Reliability and responsiveness are design concerns, not afterthoughts. Care about how the interface holds up when stakes are high and hold your team to that same standard.
- Use Honeycomb, Datadog, and Rollbar to understand and improve your systems. Operational data drives stability, not just incident response.
- You'll notice gaps and close them. When a gap reflects something broken in how the team works, you fix that too.
Requirements
- 5+ years of production full-stack experience, with latency, responsiveness, and reliability treated as design concerns, not afterthoughts.
- Strong React and TypeScript.
- Comfortable owning backend services in Go: API design, data modeling, service integration.
- You lead architectural decisions on complex systems. You make conscious tradeoffs, document your reasoning, and create the foundation others build on.
- You turn unclear requirements into a direction the team can execute on.
- You mentor engineers, give direct feedback on technical direction, and raise the quality bar through how you engage in reviews and design discussions, not just what you ship.
Benefits
- We will ensure that individuals with disabilities are provided reasonable accommodation to participate in the job application or interview process, to perform essential job functions, and to receive other benefits and privileges of employment.
