About this role, in Mercor's words
We are seeking expert physicists to author and review high-quality academic assessment content for an AI research initiative. You will write and verify rigorous multiple-choice questions across core physics domains, evaluate solution quality, and help establish gold-standard benchmarks used to advance AI capabilities.
What you'll do
Key Responsibilities
- Author original physics questions that test deep conceptual understanding, not surface-level recall
- Ensure questions are unambiguous, self-contained, and precisely defined — all necessary information must be in the problem statement
- Rate each question's difficulty: Medium (intro undergraduate), Hard (advanced undergraduate), or Expert (post-graduate and above)
Show all 7 itemsHide the other 4 in Key Responsibilities
- Provide 1 correct answer and 9 plausible but subtly incorrect alternatives that challenge expert-level solvers
- Write step-by-step Chain-of-Thought solutions with clear, concise intermediate steps in markdown format
- Supply 1–5 academic references per question from reputable sources (peer-reviewed journals, university repositories)
- For verification tasks: flag issues with clarity, completeness, precision, or solvability and justify any edits made
Candidate background
Ideal Qualifications
- PhD or doctoral candidate in Physics, Applied Physics, Astrophysics, or a closely related field
- Master's degree considered for candidates with exceptional depth in a specific subdomain
- Strong command of graduate-level physics concepts and mathematical formalism
- Experience with rigorous academic problem design or physics olympiad writing is a strong plus
- Excellent written English and ability to express complex ideas clearly and concisely

Role Overview
We are seeking expert physicists to author and review high-quality academic assessment content for an AI research initiative. You will write and verify rigorous multiple-choice questions across core physics domains, evaluate solution quality, and help establish gold-standard benchmarks used to advance AI capabilities.
You will be assigned one of two task types:
• Question Authoring — Create original, challenging multiple-choice questions in your area of physics expertise, rate their difficulty, and submit them for review.
• Question Verification — Review pre-written questions for accuracy, clarity, and rigor. Edit where needed, rate difficulty, and document any changes made.
Physics Domains Covered
Semiconductor Physics, Nanoelectronics & Spintronics, Photonics, Quantum Optics & Ultrafast, Quantum Sensing & Metrology, Plasma Physics & Fusion Energy, Nonlinear Dynamics & Turbulence, Geophysics & Reservoir Simulation.
Key Responsibilities
• Author original physics questions that test deep conceptual understanding, not surface-level recall

More About the Opportunity
• Expected commitment: 10+ hours/week
• Asynchronous, fully remote work

What the platform publishes in general. These are not extra terms confirmed for this particular role.
- Getting paid
- Hourly work is paid every Wednesday for the previous week, through Stripe Connect or Wise, whichever Mercor assigns to your region. Stripe holds the first payout for 7 days. talent.docs.mercor.com/how-to/payments, talent.docs.mercor.com/policies/contracts
- Before your first paid task
- An AI interview of about 20 minutes, reused for other roles that need it, then any assessments the role asks for. Before logging hours: ID verification through Persona, a tax form, the contract documents, the Insightful time tracker, and a background check the onboarding guide says usually takes one to two weeks. talent.docs.mercor.com/support/ai-interview, talent.docs.mercor.com/how-to/apply, talent.docs.mercor.com/policies/contracts, talent.docs.mercor.com/how-to/id-verification, talent.docs.mercor.com/working/project-onboarding
- How much work
- Hearing back after the AI interview usually takes 2 to 4 weeks. When a project ends you are not moved to a new one automatically. talent.docs.mercor.com/support/ai-interview, talent.docs.mercor.com/support/project
- Contract
- Independent contractor with Mercor.io Corporation of San Francisco, which deducts no taxes. talent.docs.mercor.com/policies/taxes-work-authorization, talent.docs.mercor.com/support/legal

Alex's experience on MercorA personal account, not a promise about your project
Alexruns this site and has worked on Mercor himself. Written 31 Aug 2026.
- Every interview I took used an AI interviewer. They always checked my microphone and camera and asked me to share my screen, and some included a timed exercise of around 25 minutes.
- Many later applications needed no new interview from me. With the required assessments complete and no other outstanding steps, applying could be close to one click.
- The application I checked did not ask for a rate. My offer matched my minimum in Work Preferences. That does not establish that Mercor always caps higher offers at your preference.
- Onboarding and setup came to about 4 hours, with more security and tool setup. Of the three platforms I worked on, it was the most complicated for me. That is an estimate from my projects, not a platform average.
- Mercor required the Insightful tracker on my project. I observed app and website usage monitoring, and I am unsure which screenshot settings applied, so check the configuration.
- I was paid for hours logged, once every 14 days, and I have not experienced late or incorrect payments. That was my arrangement. Mercor's current documentation describes weekly payout cycles, so check your own offer.
One person's applications, not a promise about yours.
