Full Stack Engineer Jobs in the United States

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-informed product development with platform engineering.

What You'll Do

• Build product experiences for investigating agent behavior, evaluating results, debugging execution paths, and verifying and replaying workflows.

• Work directly with customers to understand agent failures, define product solutions, and iterate on shipped features.

• Develop across the stack, with an emphasis on APIs, data models, backend systems, and polished product interfaces.

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

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

• Collaborate with AI teams to translate real-world agent challenges into product improvements.

What We're Looking For

• Typically 5 to 8 years of full-stack product engineering experience, with strong backend skills and experience shipping end-to-end.

• Proficiency with TypeScript, React or Next.js, and Python or Node.js; experience with PostgreSQL is relevant.

• Experience building polished user-facing products, designing APIs and data models, and debugging production issues across the stack.

• Hands-on experience with AI agents, LLM-powered products, or agentic systems, including relevant tooling and evaluation or debugging workflows.

• Strong software engineering fundamentals, a formal computer science degree or equivalent academic background, and the ability to influence product decisions through engineering.

• Customer-facing product experience and familiarity with developer tools such as APIs, SDKs, or command-line workflows are valuable.
