 The Role:
 
 
 
 Factor Law is hiring a Full Stack AI Engineer to build production-grade AI products for complex legal workflows. This is a hands-on engineering role for someone who can move confidently from backend architecture to frontend delivery, from document ingestion to user experience, and from prototype to production without waiting for detailed step-by-step instructions.
 
 
 You will join a high-autonomy product and engineering environment building AI-powered tools that help legal teams work faster, more accurately and with more confidence. The work will sit at the intersection of contract intelligence, document processing, retrieval, AI orchestration, workflow automation, enterprise authentication, asynchronous job handling and complex user interfaces.
 
 
 This role is for a builder. We are looking for someone who can use AI-assisted coding tools aggressively and responsibly, particularly Codex , while still owning correctness, security, maintainability and production quality. The right person will use AI to move faster, not to cut corners.
