Computational Fluid Dynamics (CFD) AI Evaluation Engineer - Remote, Part-Time Contract

Company: OpenTrain AI

Location: Remote (open in 52 countries, including the United States, Canada, the United Kingdom, Germany, France, India and Brazil)

Evaluate AI-generated answers to advanced CFD problems: meshing, turbulence modelling, multiphase flow, heat transfer, multiphysics and solver setup. You solve the problem yourself, judge whether the AI's technical answer is correct and sound, and explain your findings in writing.

The work

- Review CFD problems on mesh generation, turbulence models (RANS, LES, DES), boundary conditions and solver configuration.

- Troubleshoot with mesh-independence studies, turbulence-model selection and convergence analysis.

- Validate flow, heat-transfer and multiphysics results against experimental or analytical data.

- Write clear feedback that helps improve how AI systems solve and explain engineering simulations.

What it takes

- At least 3 years of hands-on CFD simulation and validation experience (preferred).

- A bachelor's degree or higher in mechanical, aerospace or chemical engineering, fluid dynamics or thermofluids, or equivalent practical experience.

- Strong knowledge of the Navier-Stokes equations and verification and validation (for example ASME V&V 20, AIAA CFD V&V guidance).

- Excellent written and verbal English proficiency.

Pay and terms

- $50 to $150 per hour equivalent, paid per task that meets the project specifications.

- Remote, part-time, independent contractor.
