Where

Remote. The listing data we read does not name a country list. Mercor pays in some countries only, so confirm you are eligible when you apply.

Screening

Apply with a CV, confirm where you work from, and take a short AI interview of about 20 minutes. Mercor then verifies your background and adds you to the machine learning pool.

Role details

This is a standing Mercor listing for machine learning practitioners, not a single short-term vacancy. The posting says it stays open whether or not a matching project is running this week, and that new projects can start at short notice.

Work in this pool, as Mercor describes it, includes writing modelling problems from systems you have actually shipped, with data, objectives, constraints and a reference answer; grading model-written training and evaluation code; and flagging approaches that would train cleanly but fail in production. Comparable projects, the posting says, have paid $70 to $120 an hour, set per project by scope and depth.

How hiring works

You apply with a résumé, confirm where you work from, and take a short AI interview of about 20 minutes. Mercor says it verifies your background and adds you to the pool, then invites matching people when a project starts. That later invitation names the rate, hours and client.
