Chemistry Expert (Spain)

Location: Remote

Type: Contract / Part-time

Commitment: 10-20 hours per week

Compensation: Up to 40 USD / hr

Project duration: 2 months , with potential extension

About the role

We create high-quality STEM training data for frontier AI models that is directly used in training and evaluation workflows at leading AI labs.

We are looking for experts in Chemistry to design advanced, deterministic problems with exactly one verifiable correct answer. These problems should challenge modern AI systems with deep reasoning, domain knowledge, and computational rigor.

Projects may include computational chemistry, physical chemistry, analytical chemistry, chemical engineering-adjacent workflows, and chemistry tasks requiring specialized software tools.

What you’ll do

Design difficult chemistry problems that reflect real scientific workflows

Create deterministic tasks with one correct answer and full verified solutions

Develop reasoning-intensive and computationally grounded problems

Use Python and, where appropriate, domain-specific chemistry tools or simulation packages

Ensure all tasks are reproducible, technically precise, and clearly documented

Write concise and rigorous technical explanations in English

What we’re looking for

Master’s or PhD in Chemistry or a related field

Research or industry experience involving computational or quantitative chemistry workflows

Strong Python skills; familiarity with scientific libraries

Strong understanding of modeling, numerical approaches, and chemical reasoning

Ability to design original, difficult problems that go beyond textbook recall

Excellent attention to detail and clear technical writing

Nice to have

Experience with computational chemistry, cheminformatics, spectroscopy analysis, molecular modeling, or specialized chemistry software

Experience with professional chemistry workflows involving simulation or data analysis tools

Experience creating technical evaluation content

Compensation: $40 per hour
