About the role

About the job: 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 modified gravity, Palatini tetrad formulations, FRW cosmology, quadratic inflation, and related gravitational systems. Depending on expertise and seniority, contributors may participate as Solvers, Auditors, or Adjudicators. No prior experience in AI is required.
Key Responsibilities:
  • Palatini Gravity & Geometric Formalism
  • Develop and review solutions using first-order gravitational formulations
  • Work with independent tetrad and spin-connection variables
  • Derive field equations, curvature, and torsion contributions
  • Verify local Lorentz structure, index conventions, signs, and normalisation
  • Compare alternative geometric formulations for mathematical consistency
  • Chern-Simons Gravity & Cosmology
  • Analyse Dynamical Chern-Simons and related modified-gravity models
  • Evaluate parity-violating terms, scalar couplings, and Pontryagin-density contributions
  • Determine when symmetry assumptions suppress or preserve modified-gravity terms
  • Formulate and analyse torsion-modified Friedmann equations
  • Interpret departures from standard FRW dynamics across relevant cosmological regimesODEs, Numerical Analysis & Benchmark ReviewDerive and solve coupled nonlinear cosmological ODE systems
  • Apply analytical and numerical integration methods and assess sensitivity to initial conditions
  • Use Planck-unit normalisation and verify dimensional consistency
  • Audit derivations, numerical implementations, and physical interpretations
  • Produce complete solutions, technical reviews, or adjudications depending on project role
  • Ideal Profile
  • PhD or equivalent advanced research experience in Physics
  • Strong background in gravitation, cosmology, astrophysics, or mathematical relativity
  • Hands-on experience with first-order Palatini gravity
  • Strong knowledge of tetrad and spin-connection formalisms
  • Familiarity with torsion and modified-gravity corrections
  • Experience with Dynamical Chern-Simons gravity and Pontryagin density
  • Ability to derive and solve nonlinear cosmological ODE systems
  • Strong numerical-integration and analytical reasoning skills
  • Experience interpreting modified Friedmann dynamics
  • Practical familiarity with Planck-unit normalisation
  • Ability to produce rigorous research-level written explanations
  • No prior AI-training or model-evaluation experience is required
  • Engagement Details
  • Independent contractor engagement
  • Fully remote

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
