CFD Engineer Contractor (Remote, AI Training)

What You'll Do7

• Work through advanced CFD problems covering mesh generation, turbulence modeling, multiphase flow, heat transfer, and solver configuration.
• Check AI-generated technical responses for correctness, accuracy, and engineering soundness.
• Apply practical engineering judgment to simulation scenarios and theoretical fluid-dynamics questions.
• Troubleshoot CFD issues using best practices like mesh independence, turbulence model selection, boundary-condition specification, and convergence analysis.
• Use your domain expertise to help refine how AI reasons about computational fluid dynamics.
• Document your feedback and provide clear written and verbal explanations to support AI learning.
• Collaborate with a distributed network of technical experts and project participants.

Requirements7

• Bachelor'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.
• At 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.
• Deep understanding of Navier-Stokes equations, turbulence modeling (RANS, LES, DES), meshing strategies, boundary-condition specification, and verification & validation practices.
• Proven ability to analyze and validate fluid flow, heat-transfer, and multiphysics problems using CFD tools, cross-referencing with experimental or analytical data.
• Familiarity with relevant standards such as ASME V&V 20, AIAA CFD verification & validation, or ITTC procedures.
• Excellent English proficiency with strong written and verbal communication skills.
• Experience 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.
