About the Role
Join an early-stage legal technology team building AI-powered software for contract review and other legal workflows. As a founding product engineer, you will work closely with attorneys and AI engineers to turn real-world needs into reliable product features, while helping establish engineering practices as the team grows.
What You'll Do
-
Build and own full-stack product features, from data models and backend systems to interfaces used by attorneys and clients.
-
Partner with attorneys and AI engineers to translate legal workflows and review playbooks into production software.
-
Make pragmatic architecture and tooling decisions that support fast delivery and long-term maintainability.
-
Write reliable, maintainable code and take ownership of features through production deployment.
-
Help shape engineering standards, team culture, and hiring as the team expands.
-
Work directly with teammates to deliver a high-quality customer experience in a fast-moving environment.
What We're Looking For
-
1 to 3 years of experience building and shipping production software, ideally at an early-stage company or as a founder.
-
Full-stack development skills, including TypeScript and React, a modern backend stack, and relational databases.
-
Hands-on experience building with AI or large language models, through professional work or personal projects.
-
Experience owning features end-to-end and making sound engineering trade-offs under time constraints.
-
Strong product instincts, communication, and judgment, with the ability to work through ambiguity and take ownership.
-
Legal technology, contract management, document processing, or work with attorneys or other domain experts is a plus.
