• Write concise justifications grounded in the source documents and applicable US law
• Create realistic legal prompts, fact patterns and model answers drawn from your litigation experience
• Flag errors, gaps and risky advice in AI-generated legal content
• Attend onboarding and calibration sessions

What you’ll bring

• Are admitted to practice in at least one US state (active bar membership)
• Have 3+ years of US litigation practice, such as civil or commercial litigation, motion practice, discovery and trial preparation
• Hold a J.D. from an ABA-accredited law school
