From the Mercor listing

Mercor is seeking Physics PhD’s (Graduated) specializing in one of the following sub-domains:

  • Statistical Mechanics, Condensed Matter & AMO Physics

  • Advanced Quantum, Electrodynamics & Classical Mechanics

  • String theory, QFT, Particle physics & Nuclear physics

  • General Relativity, Astrophysics & Cosmology

In this role, you will contribute your subject matter expertise to a cutting-edge project involving state-of-the-art large language models. Specifically, you will help create high-quality data that will inform the future of AI innovation by coming up with difficult problems in your domain.

You're a good fit if you:

  • Hold a PhD in Physics

  • Received your graduate degree in US/UK/Canada/Western Europe

  • Have high attention to detail

  • Have exceptional written and verbal communication skills

  • Have excellent proficiency in English

Here are more details about the role:

  • The role is ongoing starting in February and continuing with rolling applications

  • Experts are expected to contribute 4-6 tasks per week, each taking several hours to complete

  • The work will require rigorous physics expertise and ability to follow complex instructions

Screening Process:

  • You will need to complete a short AI interview and form - the whole application process should last 20-40 minutes

Requirements

  • Must be eligible to work in one of: Remote, Canada, Europe, etc.
  • Fluent proficiency in English (Written & Verbal)
  • Reliable high-speed internet connection
  • PhD's degree or equivalent professional experience
  • Demonstrated expertise in STEM

How long hiring takes

Why this role

At $80–$100/hr, this Physics PhD position compensates STEM expertise on its own terms, the kind of rate that would otherwise only show up inside a law firm, hospital, or research lab.

Talent pool

We're light on STEM candidates

We've matched 65 people with a STEM background against 726 STEM listings we've tracked, so most go out without one. Set up a profile and we'll consider you for a role like this one.

Common questions

Does Mercor's application require an on-camera interview?

Yes, every applicant records a video interview with an AI interviewer that asks questions about your resume. Clients review that recording to judge communication skills before matching, so there's no way to apply without going on camera.

Does it cost money to apply to Mercor?

No, applying and joining Mercor is free. Mercor's revenue comes from a fee it charges the client on top of your hourly rate, not from applicants. Treat any request for payment to join as a red flag.

Is academic-niche AI training a continuous job?

Usually not. Work runs in campaigns, like training a model specifically on quantum mechanics, that might last a few weeks. Treat it as a high-paying fellowship or grant rather than a permanent daily job.

Is academic-niche AI training just data labeling?

No, it's closer to academic research. Expect to write or verify complex proofs, solve advanced equations, or check the logic behind a model's step-by-step reasoning. The goal is teaching AI systems to reason deeply within your specific field.

What does STEM work look like for a Physics PhD?

Tasks here are scoped to STEM, not generic labeling. As a Physics PhD, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to STEM) rather than following a one-size-fits-all rubric. If you don't have hands-on STEM background, this is likely not the right listing to start with.

What specific skills does this listing call for?

English, Expert, and PhD are named directly in the listing. If you don't have hands-on experience with these, expect the screening process to test for them directly rather than accepting adjacent experience as a substitute.

How much does this specific role pay?

This listing is posted at $80–$100/hr, an hourly rate. The range reflects experience level and negotiated terms, not a placeholder, so where you land in it depends on your background and the assessment. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.

What happens when I click Apply on this listing?

You'll be taken to Mercor's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.

Is a PhD required?

For this specific role, yes, or near-equivalent professional depth. The credential gate is enforced at the assessment stage, not just on paper. That said, active PhD candidates and people with equivalent published research have qualified without a formal degree. The assessment is the real filter.

Can I apply from outside Canada, Europe, or the United Kingdom?

This specific role is open only to people based in Canada, Europe, and the United Kingdom. If you are somewhere else, applying is unlikely to lead to an offer even if you pass the assessment, because the restriction is usually about where the work can legally be contracted rather than your skills. Read the full description for any tax-residency or right-to-work caveats before you apply, since they can differ by country.

How soon will I start working after applying to Mercor?

Not immediately. Mercor is a talent marketplace, not a task queue, so applying puts you in a pool of candidates. You start working only once a specific client, like a major AI lab, selects your profile, and that matching process can take weeks.
