Location: London
Job Description:

What you’ll do

Mercor is partnering with leading AI labs to advance frontier agent evaluations in executive and office administration. As an Executive Assistant & Admin Operations Expert, you’ll build long‑horizon admin 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:

  • Executive support: calendar triage against defined priority rules, multi‑timezone scheduling with feasibility constraints, travel booking against budget and calendar windows
  • Expense and procurement: expense reports against policy with known approvals/denials, purchase requests against rule‑based limits
  • Office operations: service tickets routed against a defined owner map, document filing against a taxonomy

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

Who we’re looking for

  • 3+ years as an EA, office manager, or senior admin supporting busy principals
  • Expertise in one or more of the following: principal‑level calendar triage and multi‑timezone scheduling, expense systems (Concur, Expensify, Ramp), corporate travel platforms (Navan, TravelPerk), async comms operations
  • Comfortable reading and producing admin artifacts: itineraries, agendas, expense packages, service tickets
  • Clear written communication; can articulate reasoning step by step and encode it into deterministic rubrics
  • Located in the United States or Canada

Compensation

$45–$60/hr depending on domain depth and prior experience. Strong contributors are promoted based on task quality and throughput.
