Crossing Hurdles is seeking a CFD Engineer to evaluate and solve advanced computational fluid dynamics challenges and assess AI-generated technical responses. The role involves applying engineering judgment, validating simulations, documenting feedback, and collaborating remotely with technical experts.

Responsibilities

• Evaluate and solve advanced CFD challenges involving mesh generation, turbulence modeling, multiphase flow, heat transfer, and solver configuration
• Review and assess AI-generated technical responses for correctness, accuracy, and engineering integrity
• Apply practical engineering judgment to simulation scenarios and theoretical fluid-dynamics questions
• Analyze and troubleshoot CFD problems using best practices such as mesh independence, turbulence model selection, boundary-condition specification, and convergence analysis
• Contribute domain expertise to refine and inform the reasoning capabilities of AI in computational fluid dynamics
• Document feedback and provide clear written and verbal explanations that enhance AI learning and performance
• Collaborate remotely within a distributed network of technical experts and project participants

Skills

• Bachelor s degree or higher in Mechanical Engineering, Aerospace Engineering, Chemical Engineering, or a related field with a focus on fluid dynamics or thermofluids; or equivalent practical experience
• Have strong relevant experience conducting and validating CFD simulations, including mesh generation, solver setup, turbulence modeling, multiphase/heat-transfer analysis, or post-processing
• 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 and practices (e.g., ASME V&V 20, AIAA CFD verification & validation, ITTC procedures)
• Excellent English proficiency with outstanding written and verbal communication skills
• Experience with CFD software (such as ANSYS Fluent, STAR-CCM+, OpenFOAM, COMSOL, or Converge) is a strong plus

Benefits

• Remote work
