Job Description: Join as the second engineer at a stealth startup automating complex legal workflows for international founders. You will own product end-to-end, building intelligent systems for case preparation and evidence analysis. This role offers the unique opportunity to define the technical architecture of an AI-first firm backed by world-class industry leaders.

What You Will Do:
- Architect and ship across the full stack using a modern TypeScript monorepo, including React, Radix, and oRPC with a Drizzle/Postgres backend.
- Design and implement AI agents using OpenAI, Claude, and Gemini to automate document generation, legal research, and client communications.
- Collaborate directly with users and founders to define product features, iterating rapidly from concept to production-ready legal tools.
The ideal candidate:
- Deep expertise in production TypeScript across the full stack and a strong intuition for software design principles beyond simple code generation.
- Hands-on experience building with LLM providers or agent frameworks, with the ability to direct AI tools to produce high-quality, maintainable code.
