About the Role

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 labs partner with Mercor to build the high-quality code and reasoning data that trains their frontier models. As a member of Research Ops on the Code team, you will own multi-million-dollar data programs end to end — and ownership here is technical as much as operational. You will:

This role sits at the intersection of operator and builder. You'll spend as much time reasoning about designing tasks which fail frontier models in fair ways, designing verifiers with parity to production codebases, and constructing self-contained environments which capture real world tasks, as you will on delivery and quality. We operate with startup intensity: occasionally responsive on weekends, always a high bar. The upside is that performance incentives, high-slope career trajectory, and meaningful equity reflects that intensity.

What We're Looking For

We hire for range: people who can hold a credible technical conversation with a lab researcher in the morning and design the expert workflow that produces the data in the afternoon.

Required

Bonus — a distinctive spike in one of these stands out

Backgrounds that often fit: ML/data/software engineers who love operating, technical PMs, research engineers, or strong generalist operators with real technical range. Backgrounds from consulting, finance, or high-growth startups can work if paired with real technical fluency.
