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.
