Engagement Manager, Legal

Mercor's mission is to organize human intelligence to power the AI economy. We're a leading AI data company, building the layer between human expertise and frontier models. Millions of domain experts on the platform are paid over $4 million per day to train frontier AI models. Mercor's APEX benchmark family measures AI's real-world impact on professional work. Mercor Enterprise brings this same infrastructure to Fortune 500 companies: helping companies capture how their best people actually work, translating that expertise directly back into agents.

Mercor is creating a new category of work where expertise powers AI advancement. Achieving this requires an ambitious, fast-paced and deeply committed team. You’ll work alongside researchers, operators, and AI companies at the forefront of shaping the systems that are redefining society. Mercor is a profitable Series C company valued at $10 billion. We work in-person five days a week in our San Francisco, NYC, or London offices.

As an Legal Engagement Manager, you will help legal tech companies, application-layer AI companies, and law firms post-train and evaluate models for legal work. You'll serve as their primary point of contact from first conversation through delivery.

Your legal training is central to the role. You'll help customers define what high-quality legal work looks like, turn it into evaluations and training data, and work with Mercor's network of lawyers to produce it. You'll also lead commercial processes for new and existing customers and help leadership find and unblock growth in the legal market.
