Physicist, PhD
up to $120/hr
About this role, in Alignerr's words
What if your years of physics expertise could directly shape how AI reasons through the most complex problems in science? We're looking for PhD-level physicists to evaluate, critique, and help build the training data that teaches frontier AI models to think rigorously — from quantum mechanics to thermodynamics to electromagnetism.
What you'll do
- Develop and refine advanced physics questions spanning specialized subfields — from classical mechanics to quantum field theory
- Review and evaluate AI-generated solutions to physics problems, identifying errors, logical gaps, and conceptual misunderstandings
- Annotate and categorize physics problems, concepts, diagrams, and experimental data to support model training
Show all 6 itemsHide the other 3 in What you'll do
- Map relationships between key physics principles and subfields to help AI models grasp the structure of the discipline
- Contribute to building high-quality training datasets that span a full range of topics and difficulty levels
- Provide clear, structured feedback that directly improves how AI models reason through scientific problems
Candidate background
Who You Are
- You hold a PhD in physics or a closely related field, with demonstrated expertise through research, teaching, or advanced problem-solving
- You have experience developing or critically reviewing sophisticated scientific content — such as research publications, curriculum design, problem sets, or technical simulations
- You can communicate complex physical concepts with clarity, and enjoy translating abstract theory into precise, well-reasoned explanations
- You're detail-oriented, methodical, and hold yourself to a high standard of scientific rigor
- You're self-motivated and comfortable working independently in an asynchronous environment
Nice to Have

Physicist, PhD (AI Training)
About the Role
What if your years of physics expertise could directly shape how AI reasons through the most complex problems in science? We're looking for PhD-level physicists to evaluate, critique, and help build the training data that teaches frontier AI models to think rigorously — from quantum mechanics to thermodynamics to electromagnetism.
This is a fully remote, flexible contract role. No AI background needed — just deep domain expertise, a sharp analytical mind, and a passion for scientific precision.
- Type: Hourly Contract - Location: Remote - Commitment: Minimum 15 hours/week, fully asynchronous
What You'll Do
* Develop and refine advanced physics questions spanning specialized subfields — from classical mechanics to quantum field theory * Review and evaluate AI-generated solutions to physics problems, identifying errors, logical gaps, and conceptual misunderstandings * Annotate and categorize physics problems, concepts, diagrams, and experimental data to support model training * Map relationships between key physics principles and subfields to help AI models grasp the structure of the discipline * Contribute to building high-quality training datasets that span a full range of topics and difficulty levels * Provide clear, structured feedback that directly improves how AI models reason through scientific problems
