Analytical & Physical Chemist

Use your hands-on experience in chemistry to write research-level problems for AI models. Remote, flexible contract work.

AfterQuery works with leading AI labs to build the expert data that tests and trains AI models. We're looking for analytical and physical chemists who work with raw lab measurements: the titrations, spectra, calorimetry, electrochemistry and kinetics runs you turn into results.

Requirements

• Technical: Working knowledge of Python for fitting and analyzing your own measurements.

Preferred

• Background: a Master's or PhD in chemistry with substantial bench time; method validation or QC lab experience is a strong signal.
• Hands-on work with real data, rather than synthesis-only organic chemistry or purely computational chemistry.

Contract and pay

Flexible, independent-contractor work: $300 per approved task, about 6 hours each (roughly $50 per hour), with no cap on how many tasks you take on.

All accepted experts undergo standard background and identity verification.

Required qualifications

• Hands-on experience working with your own raw lab measurements in Python or a similar language
• Able to write clearly about technical work in your field
• Able to work independently and manage your own time. This is flexible, task-based work with no fixed weekly schedule

Why apply

• $300 per approved task (roughly $50 per hour)
• Fully remote and flexible, with no fixed weekly schedule
