How this pay compares

The title points to rating and reviewing ai output: judging a model's answers or code against guidelines, such as which of two is better or whether one is correct and safe. What each kind of AI training work pays

At $42/hr, this role pays more than 4% of the 51 open chemistry roles with a listed pay range, below the median of $83.

Open chemistry roles that ask for a PhD have a median of $79/hr (32 roles).

Among platforms with 10 or more priced chemistry roles, Mercor has the highest median ($85/hr across 11 roles) and OpenTrain AI the lowest ($75/hr across 25).

OpenTrain AI roles that closed since late October stayed listed a median of 31 days (122 roles). OpenTrain AI posted this one 6 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.

The work

Create advanced chemistry problems and scenarios based on real computational workflows, then evaluate AI-generated answers for accuracy and reproducibility. The work focuses on established approaches to simulation, modeling, reactions, and thermodynamics.

The duties and qualifications need review before applying.

  • Write expert-level problems grounded in computational chemistry workflows.
  • Review AI responses against accepted computational practice.
  • Give structured written feedback that explains errors and how responses can improve.
  • Apply your judgment in areas such as quantum chemistry, molecular dynamics, cheminformatics, reaction modeling, or thermodynamic modeling.

What it pays and takes

  • Pay: Up to $42 per hour.
  • Time: 20+ hours per week, with a flexible schedule.
  • Location: Open to candidates in India.
  • Work type: Part-time, project-based contract work that can be done remotely alongside another role.
  • Education: A PhD in computational, physical, or theoretical chemistry, or an MS plus experience in the pharmaceutical or materials industry.
  • Experience: First-author publications or experience running production-scale simulation or DFT workflows.
  • Expertise: Depth in quantum chemistry, molecular dynamics, cheminformatics, or reaction modeling. Candidates who meet at least two of the three core qualifications are encouraged to apply.
  • Communication: Strong written English and the ability to explain complex chemistry clearly.
  • Work style: Attention to detail and the ability to work independently in a remote, asynchronous setting.
  • Helpful experience: Multiple tools such as Gaussian, ORCA, Psi4, VASP, GROMACS, LAMMPS, or RDKit, and production simulation or DFT pipelines in pharmaceutical, materials, or energy research.
