About AI training and this opportunity

AI training is the human side of building intelligent systems: experts create, review, and validate examples that modern models learn from. This role sits at the intersection of computational chemistry and AI training — you will craft problems and verified solutions that teach models advanced reasoning in physical and quantum chemistry.

These projects are remote, part-time, and project-based, and they often reward deep expertise and rigorous scientific thinking.

• Contribute directly to how AI systems learn to solve research-level chemical problems.
• Flexible, remote contractor work suitable for experienced researchers and practitioners.

The role

We are hiring a Computational Chemistry Problem Designer to write original, research-grade problem statements and fully verified solutions that require advanced reasoning in physical chemistry, quantum chemistry, and molecular modeling.

You will use Python and computational chemistry libraries to implement and validate problem sets. Problems should model authentic research workflows and must not be trivially solvable by hand.

• Part-time, contractor role with a typical commitment of 20+ hours per week.
• Project-based compensation linked to complexity and required expertise.

What you'll do

Produce original computational chemistry problems suitable for training and evaluating advanced models. Each task includes a formal problem statement and a comprehensive, research-grade solution that has been fully verified with code.

Validate solutions using Python and relevant computational chemistry libraries; conduct code annotation or review when required.

• Design problem statements that replicate authentic research workflows.
• Implement and test solutions in Python using computational chemistry toolkits.
• Provide fully worked, verifiable solutions and clear scientific documentation.
• Participate in code annotation or review to support model evaluation and dataset quality.

Requirements

You must meet all core qualifications listed below. These are strict requirements because the work is research-level and used to evaluate advanced models.

CV must be in English and indicate your level of English proficiency; include an email address and phone number on your CV.

• PhD in chemistry or a closely related field (required).
• 3+ years of computational chemistry experience (required).
• Expertise in physical chemistry and quantum chemistry at the research level.
• Proficient in Python and comfortable using computational chemistry libraries.
• Strong scientific writing skills and experience developing research problems.
• Hands-on code annotation or review experience.
• Research-level computational and quantum chemistry subject-matter familiarity.

Compensation, schedule, and contract

This is contractor, part-time work. Expect a typical time commitment of 20+ hours per week, with project-based assignments available.

Compensation is hourly and linked to task complexity and required expertise. Rates range up to $60 USD per hour, with the posted range covering $15–$60 USD/hr depending on the task.

• Employment types: Contractor, Part-time.
• Pay structure: Hourly, paid in USD; final rate depends on task complexity and expertise.

How to apply and eligibility

To apply, submit a CV in English that states your English proficiency and includes an email address and phone number. Include clear evidence of your computational chemistry background and Python experience.
