How this pay compares

At $100/hr, this role pays more than 63% of the 43 open physics roles with a listed pay range, above the median of $75.

Open physics roles that ask for a PhD have a median of $100/hr (21 roles).

Among platforms with 10 or more priced physics roles, OpenTrain AI has the highest median ($95/hr across 20 roles) and Alignerr the lowest ($45/hr across 11).

OpenTrain AI roles that closed since late October stayed listed a median of 31 days (122 roles). OpenTrain AI posted this one 3 days ago.

Computed from 2,746 open roles we track across Mercor, micro1, Handshake AI, Alignerr, Appen and OpenTrain AI, refreshed daily. Midpoints of listed ranges; “up to” ceilings are left out of medians.

Tax
Contract pay arrives with no tax withheld. A US contractor at this rate and these hours would set aside about $1,643 a month for self-employment tax plus federal income tax at the 12% bracket (25%, before state tax). Outside the US, your own country's rules apply.

Open physics roles on each platform

The same kind of work, priced on every platform we track, with the best-paid open role on each.

“Up to” rows list only ceilings, so their median is a maximum, not comparable with the range midpoints above them.

The work

You will turn computational physics and astrophysics research into evaluation tasks for AI models. The tasks should reflect real scientific-computing problems and have solutions that can be checked reproducibly.

You will use work you have implemented, run, debugged, and validated. Each task should include a main problem, connected subproblems, a Python reference solution, tests, and clear standards for judging results.

  • Design original tasks based on computational research you have completed.
  • Work with simulations, numerical solvers, data-reduction pipelines, model fits, and related scientific-computing problems.
  • Define metrics and evaluation standards without relying on withheld information.
  • Revise tasks in response to structured review feedback.
  • Optionally review and calibrate tasks submitted by other experts in your field.

What it pays and takes

This is remote, flexible independent-contractor work with no fixed weekly schedule.

  • Pay: $100 per hour.
  • Schedule: Flexible, with no fixed weekly schedule and no stated cap on the number of tasks you may take on.
  • Location: Remote and open to candidates in the listed eligible countries.
  • Language: Professional fluency in English.
  • Education or research: Research-track Bachelor's study or research experience, current Master's or PhD study, postdoctoral experience, or candidate experience in physics, astrophysics, applied physics, or a closely related field.
  • Technical skills: Hands-on experience writing your own code, preferably in Python, to simulate or analyze physical systems.
  • Task design: Ability to turn an authentic computational research problem into a clear task with a reference solution and tests.
  • Work style: Ability to work independently and manage your own time as a flexible contractor.
  • Contract requirements: Ability to work as an independent contractor without visa sponsorship. F-1 students, including OPT and CPT participants, are not eligible.
  • Useful background: Condensed-matter or statistical physics, atomic, molecular, and optical physics, photonics, electromagnetics, astrophysics, cosmology, gravitation, nuclear, particle, plasma, fluid dynamics, nonlinear physics, or continuum mechanics.
  • Helpful evidence: Public code, a thesis, or papers demonstrating computational work.
