The work

Thousands of people join Mercor each week to apply for roles and sit AI-led interviews. When something breaks — an interview that won't record, an offer that won't accept, a payout that hasn't landed — you are the person who picks it up. Day to day that means reproducing the issue yourself, reading telemetry and logs, inspecting network calls, running database queries, and forming a clear view of what actually happened in production before you hand anything to engineering.

The judgment call is the core of the job. Roughly speaking, incoming reports split into three piles: genuine system defects that need an engineer, UX friction that needs clearer guidance or a configuration change, and model edge cases where an LLM behaved in an unexpected but explicable way and the fix is prompt refinement or expectation-setting. Escalating everything makes you a ticket router; resolving everything yourself buries real bugs. You will also be expected to notice patterns across tickets and raise them to engineering and product leadership, and to write runbooks so the same issue doesn't cost the same hour twice.

Because your reply is often someone's first human contact with Mercor, the writing bar is high: native-level English, informal and warm in register, precise and professional in substance. Support tone here is lighthearted, not sloppy.

What the screen looks for

  • Concrete debugging ability on modern web applications — you can talk through how you'd isolate a failure across browser, network, API, and database layers without hand-waving.
  • Hands-on familiarity with LLM behaviour: failure modes, hallucinations, prompt-sensitivity, why the same input can produce different outputs.
  • Triage reasoning under follow-up. Expect scenarios where the tidy answer is wrong.
  • Written English quality, since much of the assessment is text.

Logistics

Remote, restricted to candidates currently residing in Latin America — applications from elsewhere are not considered. Six days per week, with substantial overlap with Pacific Time, which for most of LatAm means afternoon-through-evening local hours. The platform posts a band of $35,000–$50,000; read this as annual compensation rather than an hourly figure, and as observed on the listing rather than guaranteed for any individual offer.
