About the role

Mercor is hiring PhD and Master's scientists to author AI evaluation tasks (Sci Code). You will author original, executable research problems that today's frontier models cannot solve. In this six-week, part-time role (20+ hours/week), you will source material, write prompts, build grading criteria, and calibrate against frontier models to ensure the tasks are challenging and robust. Start date is immediate, with a collaborative, research-oriented environment.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
