About this role

Preparing for this role? See the best AI tools for scientists & researchers, practise with ready-made prompts for scientists & researchers, read IBM Releases Open Source Lunar Foundation AI Model with NASA and take the free 30-day AI challenge.

Help define how frontier AI models reason about chemistry.

1. Overview

We are looking for senior chemists to improve how frontier AI models reason about real chemistry research.

Your scientific judgment is the substance of this role. You will review the quality of chemistry reasoning tasks and model outputs, write the problem specifications and reference solutions that define what "correct" looks like, and design benchmarks that show whether a model is genuinely improving. We are looking for a practicing specialist rather than a generalist.

This role is fully remote.

2. Key Responsibilities

  • Expert review: Assess chemistry tasks and model outputs, catching implausible mechanisms, infeasible reactions, stoichiometric and thermodynamic errors, misread spectra, and answers that read well but would not survive peer review.
  • Problem specs and reference solutions: Write precise problem statements and rigorous reference solutions that reflect how research chemistry is actually done.
  • Benchmarks: Design challenging, research-level problems and evaluation sets in your area of specialization.
  • Calibration: Work with other researchers and experts in adjacent fields to turn tacit expert judgment into explicit, teachable criteria.

3. Core Qualifications

  • Education: PhD in chemistry, chemical engineering, or a closely related field.
  • Seniority: A faculty appointment, principal investigator, staff or senior scientist, or an equivalent senior research role at a university, national laboratory, or research organization.
  • Domain depth: Genuine specialization in at least one area, for example organic and synthetic chemistry, physical and computational chemistry, inorganic and materials chemistry, analytical chemistry, or chemical biology.
  • Research record: A strong peer-reviewed publication record. Recognition such as competitive fellowships or awards is a plus.
  • AI fluency: Hands-on use of large language models in your work, and the judgment to tell a sound argument from a plausible-sounding wrong one.
  • Communication: Excellent written communication and the ability to give precise, well-structured feedback.
  • Location: Based in the United States.

This is a 100% remote contract role. Applicants must be located in: United States.

What to know before you apply

Pay
At the published rate, 10 hours a week would be about $900–$1,400 and 20 hours about $1,800–$2,800 before tax. Hours depend on the project, so treat this as a ceiling, not a promise.
Location
Only applicants located in United States can be paid for this role. Platforms usually verify where you are, so apply only if you are based there.
Credentials
The listing asks for a PhD. Put it in the first line of your profile: reviewers screen for it before anything else.
Timing
This listing is new today. Projects can close once they have enough people, so it is worth applying while it is open.
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.
