About the Role
Join a product engineering team building software that helps organizations improve the reliability of AI agents in production. This backend-leaning full-stack role combines customer discovery with hands-on product development, from APIs and data models to polished user-facing workflows.
What You'll Do
Build product experiences for agent investigations, evaluation workflows, trajectory debugging, verification, and replay.
Own problems end-to-end by learning from customers, defining solutions, shipping them, and iterating based on feedback.
Develop APIs, data models, internal systems, and product surfaces across the stack, with an emphasis on backend engineering.
Build systems that support large-scale investigations of production traces.
Develop platform capabilities such as workspaces, permissions, billing, usage, SDKs, and terminal-first developer experiences.
Work with AI teams to understand agent failures and translate those insights into product improvements.
What We're Looking For
Five to eight years of full-stack product engineering experience, with a backend-leaning profile and a track record of shipping production software end-to-end.
Strong TypeScript and React or Next.js skills, plus experience with Python or Node.js.
Experience building polished product interfaces, designing clean APIs, modeling data, and debugging production issues across the stack.
Hands-on experience with AI agents, LLM-powered products, or agentic systems, including familiarity with LLM APIs, evaluation or debugging tools, or agent architectures.
Ability to work directly with customers and use their needs to inform product decisions.
Strong computer science fundamentals and experience delivering high-quality software in a product-focused environment.
