About the role

As a Full Stack Engineer, you will be a key player in a 4–5 person team, taking ownership of both frontend and backend components of the AI infrastructure. You will work on agent architecture, including orchestrators and sub-agents, and ensure the AI outputs are reliable for courtroom use.

• Develop AI-powered features like document extraction and agent orchestration tailored for litigation.
• Contribute to backend optimization to enhance reliability at scale.

Why This Role Is Compelling

• Join as the 3rd founding engineer with significant equity in a pre-Series A company.
• Directly partner with the founder on UX and product decisions.
• Work on AI that matters, ensuring correctness in legal applications.
• Engage with cutting-edge agent engineering, including orchestrator/sub-agent patterns and eval loops.

The Ideal Candidate

• 3–8 years of experience in full stack development.
• Proficiency in JavaScript, TypeScript, Python, SQL, React, Next.js, and modern CSS.
• Experience with AI architectures, including LLM Agent Architectures and RAG.
• Ability to work in a fast-paced startup environment and adapt quickly to changes.
