Your work will help translate complex legal workflows into trusted, production-ready AI systems that support law firms in high-stakes moments.

• Participate in high-value client engagements, guiding technical discovery, scoping legal use cases, and building credibility with legal and technical stakeholders.
• Translate complex legal workflows, business pain points, and client goals into intelligent solution designs, technical specifications, and implementation plans.
• Design and implement AI-powered solutions for legal workflows such as contract review, litigation support, discovery automation, and regulatory analysis.
• Partner with our forward deployed engineers to build and test RAG pipelines, custom AI agents, and multi-step workflows that leverage CoCounsel, Westlaw, Practical Law, and related enterprise systems.
• Lead LLM evaluation efforts for legal use cases, including benchmarking output quality, assessing hallucination risk, testing citation quality, and validating fitness for high-stakes legal work.
• Ensure deployed solutions meet ethical AI, data protection, and enterprise security standards while maintaining the trust legal professionals expect.
• Contribute reusable solution assets and evaluate emerging AI techniques to improve quality and delivery across the team.

• JD, formal legal training, or equivalent depth of experience working within a legal practice environment.
• Fluency in legal terminology and demonstrated experience working directly with lawyers, legal teams, or legal operations stakeholders.

• Proficiency in Python.
