ABOUT MERCOR
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.
ABOUT THE ROLE
Silicon Valley’s leading AI companies partner with Mercor to scale high-quality data operations. As an SPL, you will:
- Drive the tactical execution of multi-million-dollar projects.
- Build deep client relationships with researchers at top AI labs.
- Orchestrate the work of 1,000+ contributors.
- Ensure flawless operational execution under demanding timelines.
This is a hands-on operations role for candidates excited by process optimization, rapid iteration, and high-intensity problem solving. We're an early-stage startup that operates with intensity. That means occasionally being responsive on weekends and always holding a high bar for output. The upside — performance incentives, career trajectory, and meaningful equity — reflects that.

CUSTOMER RELATIONSHIPS
- Act as the primary point of contact for leading AI labs.
- Deliver clear, consistent reporting and proactively anticipate client needs.
- Build long-term trust and identify opportunities for expansion.
