What this actually is
You design problems that stump current AI models, evaluate AI reasoning against the correct answer, write rubrics, and provide expert feedback. Often the highest-paid category because the expertise pool is small. The platform title (Applied Chemistry Benchmark Specialist) reflects the rate band and the expertise required, not the day-to-day work.
How Mercor picks people
- Upload your CV and answer the role's written questions.
- Do a video interview with Mercor's AI interviewer. Most take about 20 minutes, in English unless the role says otherwise.
- Some roles add a skills test. A test you pass once counts for similar roles.
- The project team reviews your results and sends offers to the people it picks.
Before you start
- Take Mercor's free practice interview first. It does not count toward any application.
- Use Chrome on a computer with a camera and microphone, in a quiet room.
- You can retake an official interview up to 3 times, but hiring teams see how many times you retook it.
Not every applicant gets an offer. Prepare well for the interview.

Role Overview
We are seeking expert chemists 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 chemistry 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 chemistry 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.
Chemistry Domains Covered
Materials, Polymer & Electronic Chemistry, Industrial & Process Chemistry, Energy Storage & Environmental Chemistry, Pharmaceutical & Agrochemical Chemistry, Consumer, Food & Specialty Chemicals.
Key Responsibilities
- Author original chemistry 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)
- 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
Ideal Qualifications
- PhD or doctoral candidate in Chemistry, Biochemistry, Chemical Engineering, or a closely related field
- Master's degree considered for candidates with exceptional depth in a specific subdomain
- Strong command of graduate-level chemistry concepts, reaction mechanisms, and quantitative analysis
- Experience with rigorous academic problem design or chemistry olympiad writing is a strong plus
- Excellent written English and ability to express complex ideas clearly and concisely
More About the Opportunity
- Expected commitment: 10+ hours/week
- Asynchronous, fully remote work
