About AI Training and Evaluation

AI evaluation is the human side of improving modern artificial intelligence. Expert contributors review model-generated answers, test reasoning against real technical problems, and provide precise feedback so AI systems become more accurate, useful, and trustworthy.

In this project, your computational fluid dynamics knowledge will support AI systems that interpret, solve, and explain complex engineering simulation problems. Your evaluations will help distinguish technically sound reasoning from incorrect or incomplete analysis.

• Review AI-generated technical responses
• Apply expert judgment to engineering scenarios
• Explain errors and improvements clearly
• Contribute to cutting-edge AI development from anywhere

The Role

OpenTrain AI is seeking a Computational Fluid Dynamics AI Evaluation Engineer to assess advanced CFD challenges and AI-generated engineering content. The work combines practical simulation expertise with careful evaluation of technical accuracy, reasoning quality, and engineering integrity.

This opportunity is classified as entry level, while strong hands-on CFD capability and relevant technical knowledge are expected. It is designed for an individual technical contributor working remotely on a contractor basis.

• Subject area: Computational Fluid Dynamics AI Evaluation
• Work type: Remote contractor and part-time
• Schedule: 20+ hours per week
• Languages: English
• Location: Worldwide

What You'll Do

You will evaluate and solve CFD problems spanning fluid flow, heat transfer, multiphysics, mesh generation, turbulence modeling, and solver configuration. You will also document feedback and provide clear written and verbal explanations that help improve model learning and performance.

• Evaluate advanced CFD challenges involving meshing, turbulence models, multiphase flow, heat transfer, and solver setup
• Review AI-generated engineering responses for correctness, technical accuracy, and engineering integrity
• Apply practical judgment to simulation scenarios and theoretical fluid-dynamics questions
• Troubleshoot simulations using mesh-independence studies, turbulence-model selection, boundary-condition specification, and convergence analysis
• Validate fluid-flow, heat-transfer, and multiphysics work against experimental or analytical data
• Identify technical errors and communicate precise recommendations
• Answer technical questions and explain complex CFD reasoning in writing and verbally

Required Qualifications

A bachelor's degree or higher in mechanical engineering, aerospace engineering, chemical engineering, or a related fluid-dynamics or thermofluids field is preferred. Equivalent practical experience may also qualify. At least three years of hands-on CFD simulation and validation experience is preferred.

• Hands-on experience conducting and validating CFD simulations, including meshing, solver setup, turbulence modeling, and post-processing
• Strong knowledge of the Navier-Stokes equations, RANS, LES, DES, boundary conditions, convergence analysis, and verification and validation practices
• Ability to analyze fluid-flow, heat-transfer, and multiphysics problems using CFD tools
• Ability to compare simulation results with experimental or analytical data and identify technical errors
• Excellent English proficiency
• Strong written and verbal communication skills
• Ability to explain complex CFD reasoning and provide precise technical feedback

Helpful Background

The following experience can strengthen your application, although it is presented as helpful rather than required in the role information.

• Familiarity with ASME V&V 20, AIAA CFD verification and validation, ITTC procedures, or comparable practices
• Experience with ANSYS Fluent, STAR-CCM+, OpenFOAM, COMSOL, or Converge
• Technical problem authoring
• Committee service or competition leadership
• Recognized contributions to the CFD community

Compensation and Working Arrangement

This is a worldwide remote contractor opportunity with output-based compensation. Payment is made per completed task that meets project specifications, supporting specialized engineering work that helps improve AI systems.

• Compensation range: $50 to $150 USD per hour
• Engagement: Part-time contractor
• Expected availability: 20+ hours per week
• Work arrangement: Remote and worldwide
