Early-Career Full Stack Engineer

About the Role

Join a product engineering team at an AI agent reliability startup, building tools that help teams understand and improve agents running in production. This backend-leaning full-stack role combines customer collaboration, product development, and platform engineering.

What You'll Do

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

• Own customer problems end-to-end, from understanding agent failures and defining solutions to shipping features and iterating on them.

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

• Build agent capabilities for large-scale investigations using production traces.

• Design platform systems for workspaces, permissions, billing, usage, SDKs, and developer workflows.

• Work directly with AI teams to understand their needs and inform product decisions.

What We're Looking For

• Zero to five years of full-stack development experience and a record of shipping production software end-to-end.

• Production experience with TypeScript, React, Next.js, Python, Node.js, and PostgreSQL, with a backend focus.

• Strong skills in API design, data modeling, maintainable code, and debugging across the stack.

• Experience building customer-facing product features and platform capabilities, and owning problems from discovery through delivery.

• Interest or experience in AI agents, LLM-powered products, developer tools, observability, evaluation, or debugging systems is a plus.
