Full job description
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.
You'll own cloud and infrastructure security at a company where tenant isolation is a critical enterprise requirement. Mercor's customers - including frontier AI labs - need hard guarantees that their data stays within strict boundaries. This is not a compliance checkbox role. You'll architect multi-account AWS isolation, harden Kubernetes clusters, deploy cloud security posture management, and build the infrastructure that lets Mercor serve enterprise clients who demand the highest security bar.
We use AI heavily in our own security work. You should be comfortable building alongside AI code-gen tools, using LLMs to accelerate infrastructure review and policy authoring, and automating away the repetitive work that slows infrastructure security down. If you'd rather write a Terraform module than fill out a spreadsheet, you'll fit in here.
We're in-person five days a week at our SF headquarters, with first Fridays remote.
