Physical Sciences & Engineering Professional

STEM Expert (MSc./PhD)

• Science & Research
• Platform: micro1
• Location: 58 countries

This is a remote, contract role for scientists and quantitative experts who will solve challenging problems in their field and check AI-generated answers for technical accuracy. Much of the work is hands-on Python for calculations and simulations, and candidates are expected to already use coding agents in their workflow. It suits people with deep expertise in at least one core science or mathematics area, whether gained in academia, industry, or independent work.
