Senior Software Engineer, AI

Are you ready to shape the future of legal technology with AI? Do you thrive in fast‑moving, ambiguous environments where you can build products from the ground up? We're looking for a Senior Software Engineer to join the CoCounsel Drafting team. In this role, you'll be hands‑on designing and building the systems that transform how attorneys draft, review, and refine legal documents.

You'll have the autonomy to focus on what matters most: solving complex technical problems and shipping impactful products. If you take initiative, get energized by ambiguity, and love building new products, this role is for you. Attorneys spend 60–70% of their time drafting documents. The tools we build are fundamentally transforming the practice of law—giving legal professionals countless hours back to focus on higher‑value work for their clients.

• Contribute to the reliability, observability, and performance of AI systems by ensuring low‑latency responses and high‑quality outputs within the drafting engine.
• Collaborate on technical decisions by evaluating trade‑offs, proposing solutions, and implementing complex systems.
• Thrive in ambiguity by proactively identifying problems, proposing solutions, and driving work forward without waiting for direction.
• Work cross‑functionally with Product, Design, and Research to deliver impactful features that solve real customer problems.
• Own quality and delivery by writing well‑tested, maintainable code and consistently shipping reliable software.

• A customer‑obsessed mindset—deep care for the impact your products have on real users.
• Excellent communication skills with the ability to collaborate across engineering, product, and design teams.
