Role Title:STEM Expert – Chemistry & Computational Chemistry (PhD)

Role Type:Contractor

Location: Remote (Worldwide)

Job Summary: In this role, you’ll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input.

Key Responsibilities:

  • Design, evaluate, and critique chemistry and computational chemistry problems, workflows, and reasoning chains to support AI benchmarking initiatives.
  • Provide expert-level insights on reaction mechanisms, synthesis planning, spectroscopy analysis, molecular simulations, and electronic structure methods.
  • Assess and optimize experimental protocols, simulation parameters, and software configurations for accuracy and reproducibility.
  • Analyze chemical, spectroscopic, and simulation data and provide actionable recommendations.
  • Leverage domain knowledge to guide the development and validation of chemistry-related AI models and tools.
  • Communicate complex scientific concepts clearly, both in writing and verbally, to technical and non-technical collaborators.
  • Document findings, methodologies, and best practices to ensure knowledge transfer across the customer’s team.

Areas of Expertise (we welcome applicants from any of the following):

  • Organic synthesis & reaction mechanisms
  • Inorganic & organometallic chemistry
  • Physical & theoretical chemistry
  • Analytical chemistry & spectroscopy
  • Computational chemistry & molecular dynamics
  • Cheminformatics & drug discovery
  • Materials science & polymer chemistry

Required Skills and Qualifications:

  • PhD in chemistry, computational chemistry, chemical biology, materials science, or a closely related field.
  • Hands-on research lab experience, including wet lab experience for experimental subfields, or extensive simulation-heavy research for computational subfields.
  • Deep expertise in at least one of the areas listed above.
  • Professional written and spoken English (C1 or higher).
  • Proficiency in Python and/or industry-standard tools in your subfield (e.g., Gaussian, ORCA, Psi4, GROMACS, LAMMPS, RDKit).
  • Excellent quantitative, analytical, and scientific reasoning skills.
  • Outstanding written and verbal communication abilities, with the ability to clearly document and explain technical concepts.
  • Track record of rigorous scientific problem-solving in complex chemistry domains.

Preferred Qualifications:

  • Academic experience (postdoc, research scientist, faculty, or equivalent), strongly preferred.
  • Peer-reviewed publications, patents, or contributions to open-source scientific software.
  • Experience with AI/ML-assisted chemistry workflows or benchmarking.
  • Background in drug discovery, reaction prediction, or retrosynthesis.

This is a 100% remote contract role, open to applicants worldwide in the countries the employer accepts.

What to know before you apply

Pay
At the published rate, 10 hours a week would be about $450–$900 and 20 hours about $900–$1,800 before tax. Hours depend on the project, so treat this as a ceiling, not a promise.
Openings
50 openings means this is a high-volume project. You are not competing for one seat: if you pass the test, there is room for you.
Location
Open worldwide in the countries the employer accepts. Payments usually go out through services like PayPal or Wise, so check one of them works in your country.
Credentials
The listing asks for a PhD. Put it in the first line of your profile: reviewers screen for it before anything else.
Test tips for scientists & researchers
  • Show full derivations; partial reasoning is usually marked down.
  • Check units, assumptions and limiting cases in every AI solution.
  • Write hard original problems that break the model: that skill is in demand.
