Gravitational Physics AI Training Expert

About OpenTrain

OpenTrain AI helps people build careers in AI training and data labeling, the human side of creating modern artificial intelligence. Contributors use their expertise to prepare examples, review model outputs, and provide feedback that improves advanced AI systems.

For subject-matter experts, OpenTrain offers a way to turn specialized knowledge into flexible remote contractor work while building an AI training portfolio.

About AI Training Work

AI training involves people solving problems, evaluating responses, and explaining what makes an answer accurate, rigorous, and useful. In specialized projects, expert judgment helps AI systems handle demanding technical subjects more reliably.

This role focuses on written analytical solutions and expert evaluation for research-level gravity and cosmology benchmark problems. Prior AI training experience is not required; strong subject-matter knowledge is the most important qualification.

The Role

OpenTrain AI is seeking a Gravitational Physics AI Training Expert to support AI training work involving advanced gravitation, cosmology, and theoretical physics. You will use structured human expertise, careful review, and clear written feedback to help improve AI-generated technical work.

The project is fully remote and open worldwide. Work is conducted in English as an independent contractor assignment.

• Role type: Part-time contractor
• Time commitment: Approximately 10 hours per week
• Project duration: 8 to 10 weeks
• Advertised pay: $80 to $160 per hour
• Work location: Remote, worldwide
• Working language: English

What You'll Do

You will develop, solve, and interpret demanding theoretical and computational physics problems. Your work may also include reviewing expert responses and assessing the quality, clarity, and correctness of specialized benchmark results.

• Provide detailed analytical and numerical solutions involving first-order Palatini gravity
• Work with tetrad and spin connection approaches
• Analyze Pontryagin density contributions and extended gravity theories
• Handle Friedmann equations with torsion
• Formulate, solve, and interpret coupled nonlinear cosmological ODE systems
• Critically evaluate theoretical and computational results
• Apply Planck-unit normalization consistently
• Review expert responses and assess specialized benchmark quality and clarity

Required Expertise

Applicants should have advanced academic training in physics, with an emphasis on gravitation, cosmology, astrophysics, or a related field. A PhD or equivalent background is expected for the subject-matter work.

Prior AI training experience is not required. However, you must be able to reason carefully through advanced models, communicate technical conclusions in clear written English, follow detailed guidelines, and work independently on remote contractor tasks.

• Advanced academic training in physics focused on gravitation, cosmology, astrophysics, or a related field
• Expertise in first-order Palatini gravity
• Knowledge of tetrad and spin connection formalisms
• Ability to derive, solve, and interpret nonlinear cosmological ODE systems
• Understanding of Pontryagin density and Dynamical Chern-Simons modifications
• Experience with higher-order curvature corrections
• Ability to apply Planck-unit normalization and interpret theoretical models
• Strong written English and clear technical reasoning
• Careful attention to detail and ability to follow detailed instructions
• Comfort working independently as a remote contractor
