About the Role

Join a product engineering team building tools that help organizations improve the reliability of AI agents in production. You will work across user-facing experiences and backend systems, with a focus on understanding customer problems and delivering practical solutions.

What You'll Do

  • Build product experiences for agent investigations, evaluation workflows, trajectory debugging, verification, and replay.

  • Own problems end to end, from speaking with customers and defining needs to building and iterating on solutions.

  • Develop APIs, data models, internal systems, and polished product interfaces across the stack.

  • Build systems that run large-scale investigations across production traces.

  • Design platform capabilities such as workspaces, permissions, billing, usage, SDKs, and terminal-focused developer workflows.

  • Work directly with AI teams to understand agent failures and translate those insights into product improvements.

What We're Looking For

  • 5 to 8 years of experience in full-stack product engineering, preferably with a backend emphasis.

  • Experience shipping user-facing products end to end, building polished interfaces with React or Next.js, and developing backend services.

  • Strong skills in TypeScript and React, plus Python or Node.js; familiarity with PostgreSQL is useful.

  • Ability to design clean APIs, model data effectively, and debug production issues across the stack.

  • Experience working directly with customers to identify needs and deliver product improvements.

  • Background in AI agents, LLM-powered products, agent evaluation or debugging, or developer tools is a plus.

Base salary: $230,000 to $300,000 annually. Visa sponsorship is available.
