Job description

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 hands‑on engineering with customer input to shape useful product experiences.

What You'll Do

• Build product experiences for investigating agent behavior, evaluating results, debugging trajectories, and replaying production activity.

• Work directly with customers to understand where their agents fail, turn those needs into product decisions, and iterate on solutions.

• Develop APIs, data models, internal systems, and user‑facing product features across the stack.

• Build agent capabilities that support large‑scale investigations of production traces.

• Design platform features such as workspaces, permissions, billing, usage systems, SDKs, and terminal‑first developer tools.

• Collaborate with teams deploying AI agents and use their feedback to improve the product.

What We're Looking For

• Typically 0 to 5 years of full-stack product engineering experience, with a backend focus.

• Experience shipping end-to-end products, influencing product decisions, and supporting production software.

• Strong skills in Python, TypeScript, or Node.js, plus experience with React or Next.js.

• Ability to design clean APIs, model data effectively, build polished product interfaces, and debug across the stack.

• Experience with AI agents, LLM‑powered products, agent evaluation or debugging, or developer tools is valuable.

• Comfort working in a fast‑paced startup environment and collaborating in person.
