About the role

Legal Product Builder at Carta Law focused on building AI-powered legal products, translating legal judgement into AI-ready systems, and prototyping new legal capabilities in collaboration with engineers and legal professionals.

Responsibilities

  • Build AI-powered legal products alongside engineers and product managers: Bring deep legal expertise into the product development process, helping turn complex legal work into scalable, agent driven experiences
  • Translate legal judgement into systems: Break down legal processes like contract review and compliance into the decisions, rules, workflows, exceptions, and escalation points an AI agent needs to navigate
  • Teach our agents what "good" looks like: develop examples, evaluation criteria, test cases and feedback loops that help our legal agents produce accurate, useful, and trustworthy work
  • Evaluate and improve agent performance. Test against real world scenarios, identify where the reasoning or outputs fall short, diagnose failure modes, and partner with engineers to improve them
  • Prototype new legal capabilities: use AI tools directly to experiment with prompts, workflows, and agent behaviour, moving from an idea to a working prototype before or alongside engineering to shape what we build next

Qualifications

  • Legal Background: You're a lawyer with 4+ years of substantive training and experience
  • Product Thinking: track record of identifying where legal workflows break down and proposing or building solutions
  • Technical Fluency: comfortable sparring with engineers on AI product development and translating legal judgment for technical teams
  • Communication & Autonomy: strong written communicator with sharp judgment and high degree of independence
  • Nice to have: Direct commercial contract negotiation experience; prior time at a legal tech company or in a hybrid legal/product role; familiarity with contract automation, document intelligence, or negotiation tooling; founder experience or building something from scratch
