Remote | Physics Expert (Gravitation / Cosmology / Astrophysics) — $80–$160/hour

We are sharing a specialised consulting opportunity for experienced Physics Experts in gravitation, cosmology, astrophysics, and mathematical relativity with strong expertise in first-order Palatini gravity, tetrad and spin-connection formalisms, Dynamical Chern–Simons gravity, Pontryagin density, cosmological ODE systems, torsion, and Planck-unit normalisation.

Selected professionals will contribute to a frontier research-level physics benchmark spanning Dynamical Chern–Simons gravity, Palatini tetrad formulations, FRW cosmology, quadratic inflation, and related gravitational phenomena. Depending on expertise and seniority, contributors may participate as Solvers, Auditors, or Adjudicators. No prior experience in AI is required.

• Verify dimensional consistency across derivations
• Translate between dimensionful and dimensionless formulations where required
• Ensure results remain comparable across benchmark tasks

Research Benchmark Evaluation

• Develop rigorous research-level solutions
• Audit analytical derivations and numerical implementations
• Identify conceptual, mathematical, or computational errors
• Compare alternative methods and interpretations
• Provide detailed written feedback grounded in gravitational and cosmological physics

Solver, Auditor & Adjudicator Responsibilities

• Serve as a Solver by independently developing complete technical solutions
• Serve as an Auditor by reviewing derivations, numerical work, and physical interpretations
• Serve as an Adjudicator when competing solutions require expert comparison
• Document reasoning and assumptions clearly
• Adapt responsibilities based on subfield expertise and seniority

Ideal Profile

• PhD or equivalent advanced research experience in Physics
• Strong background in gravitation, cosmology, astrophysics, or a closely related field
• Hands-on experience with first-order Palatini gravity
• Strong knowledge of tetrad and spin-connection formalisms
• Familiarity with torsion in gravitational theories
• Experience with higher-order or modified-gravity corrections

• No prior AI-training or model-evaluation experience is required

Engagement Details

• Independent contractor engagement
• Fully remote
• Compensation: $80–$160/hour
• Work will involve first-order Palatini gravity, tetrads, spin connections, Pontryagin density, Chern–Simons modifications, torsion, Friedmann equations, nonlinear ODE integration, and Planck-unit normalisation
• Contributors may participate as Solvers, Auditors, or Adjudicators depending on expertise and seniority
• Strong research-level gravitation and cosmology expertise is central to this engagement
• Assignments may involve analytical derivations, modified-gravity models, FRW cosmology, numerical evolution, and benchmark evaluation
