CFD Engineer Contractor (Remote, AI Training)
Listing checked September 7, 2026 · pay as published by Micro1
Overview
This remote contractor role puts your CFD expertise to work in a new way: helping train AI systems to reason about engineering simulation. You will solve advanced problems in mesh generation, turbulence modeling, and multiphase/heat-transfer analysis, then evaluate AI-generated answers for technical accuracy. No AI background is needed, only your domain knowledge. Your input will directly shape how models interpret and solve complex fluid dynamics challenges, from solver setup to verification and validation.
What You'll Do7
- 1Work through advanced CFD problems covering mesh generation, turbulence modeling, multiphase flow, heat transfer, and solver configuration.
- 2Check AI-generated technical responses for correctness, accuracy, and engineering soundness.
- 3Apply practical engineering judgment to simulation scenarios and theoretical fluid-dynamics questions.
- 4Troubleshoot CFD issues using best practices like mesh independence, turbulence model selection, boundary-condition specification, and convergence analysis.
- 5Use your domain expertise to help refine how AI reasons about computational fluid dynamics.
- 6Document your feedback and provide clear written and verbal explanations to support AI learning.
- 7Collaborate with a distributed network of technical experts and project participants.
Requirements7
- 1Bachelor's degree or higher in Mechanical, Aerospace, Chemical Engineering, or a related field with a focus on fluid dynamics or thermofluids, or 3+ years of practical CFD experience.
- 2At least 3 years of hands-on CFD simulation work, including mesh generation, solver setup, turbulence modeling, multiphase/heat-transfer analysis, or post-processing in industries like aerospace, automotive, energy, marine, HVAC, process, or biomedical.
- 3Deep understanding of Navier-Stokes equations, turbulence modeling (RANS, LES, DES), meshing strategies, boundary-condition specification, and verification & validation practices.
- 4Proven ability to analyze and validate fluid flow, heat-transfer, and multiphysics problems using CFD tools, cross-referencing with experimental or analytical data.
- 5Familiarity with relevant standards such as ASME V&V 20, AIAA CFD verification & validation, or ITTC procedures.
- 6Excellent English proficiency with strong written and verbal communication skills.
- 7Experience with CFD software like ANSYS Fluent, STAR-CCM+, OpenFOAM, COMSOL, or Converge is a plus, as is a history of problem-authoring, technical committee service, competition leadership, or peer-recognized contributions in the CFD community.
Who Should Apply
This role suits a CFD engineer who enjoys technical depth and can explain complex simulation concepts clearly. You should be comfortable working independently on varied problems and have a solid grasp of verification and validation practices. If you prefer hands-on simulation work over evaluating AI outputs, or if you lack strong written communication skills, this may not be the right fit. Candidates often get rejected when they cannot demonstrate practical experience with specific CFD tools or fail to show a clear understanding of turbulence modeling and mesh independence.
