Mercor is partnering with leading AI labs to advance frontier agent evaluations in HR operations. As an HR Ops Expert, you’ll build long-horizon people‑ops tasks that mirror the work you already do, each paired with a deterministic rubric that grades agent performance against verifiable ground truth. Tasks need to have checkable answers; no open‑ended essays, no subjective judgment calls.

Expect to build scenarios across:

  • Employee inquiries: policy questions with a documented correct answer, benefits questions against plan docs
  • Lifecycle events: onboarding and off‑boarding with required checklist completion, leave decisions with ground‑truth FMLA/ADA determinations
  • HRIS work: data updates with defined before/after states, benefits enrollment with rule‑based eligibility outcomes

These scenarios will be challenging and take long sessions of focus.

Who we’re looking for:

  • 3+ years in HR operations or people operations
  • Expertise in one or more of the following: an HRIS (Workday, Rippling, BambooHR, Gusto, Justworks), leave administration (FMLA, ADA), benefits administration, FLSA classification
  • Comfortable reading and producing HR artifacts: policy responses, offer letters, change forms, leave decisions
  • Clear written communication; can articulate reasoning step by step and encode it into deterministic rubrics
  • SHRM‑CP / PHR a plus
  • Located in the United States

Compensation: $55–$80/hr depending on domain depth and prior experience. Strong contributors are promoted based on task quality and throughput.
