Physics Expert - AI Trainer (Spain)

Role overview Create physics problems and verified solutions for training and evaluating AI systems on technical reasoning. The work focuses on original, challenging tasks with a single checkable answer, supported by clear reasoning and reproducible methods.

Responsibilities - Develop advanced problems that require multi-step physical reasoning rather than recall. - Ensure each task is deterministic and has exactly one verifiable answer. - Provide complete solutions and explain the reasoning clearly. - Use Python or domain tools to create simulations, models, or computational workflows where useful. - Review submissions for technical accuracy, reproducibility, and clear English.

Requirements - A master’s or doctoral degree in physics or a closely related field. - Research or industry experience in theoretical, experimental, or computational physics. - Strong Python skills and familiarity with scientific computing libraries. - Knowledge of modeling, simulation, numerical methods, and multi-step problem solving. - Ability to produce original, demanding problems grounded in real physics work. - Careful attention to detail and strong technical writing in English.

Nice to have - Experience with simulation or physics software, such as finite element, circuit simulation, or symbolic tools. - Background in computational physics, statistical mechanics, electromagnetism, quantum mechanics, or a related area. - Experience evaluating model reasoning, building benchmarks, or designing technical assessments.

Benefits and work setup - Remote contract role, part time, with a commitment of 20–40 hours per week. - Planned for two months, with a potential extension. - Compensation of up to $40 per hour.
