CFD Engineering Task Designer

The work

You will design compact engineering challenges that help AI models reason about fluid dynamics, aerodynamics, and simulation practice. The work combines technical assessment design with reviewing AI-generated answers and does not require machine-learning research experience.

Each task must be physically grounded, clear, self-contained, and objectively verifiable. You will use your CFD experience to create problems that reflect real simulation workflows.

• Design tasks covering boundary-condition selection, mesh quality, flow-regime identification, and simulation setup.
• Write precise problem statements that are unambiguous and physically sound.
• Build deterministic checkers that score model answers consistently.
• Create reference solutions showing that each task is solvable and scored correctly.
• Review and refine task accuracy, clarity, and difficulty.
• Use OpenFOAM experience to keep challenges connected to practical CFD workflows.

What it pays and takes

This is a remote, asynchronous freelance contract. The role is listed as entry level, but it requires hands-on CFD experience and strong technical knowledge.

• Pay: $80 to $110 per hour.
• Schedule: 10 to 40 hours per week; the listed commitment is 20+ hours per week.
• Location: United Kingdom.
• Language: English.
• Required: hands-on experience with OpenFOAM.
• Required: strong knowledge of fluid mechanics, aerodynamics, and heat transfer fundamentals.
• Required: practical familiarity with mesh generation, turbulence modeling, boundary conditions, and post-processing.
• Required: precise technical writing and the ability to create verifiable engineering problems.
• Required: clear communication about complex physics and reliable independent working habits.
• Preferred: a background in aerospace engineering, mechanical engineering, or a closely related field.
• Helpful: experience with other CFD solvers or multiphysics platforms, Python, Bash, MATLAB, design optimization, flow control, adjoint methods, propulsion, computational research, or technical assessment writing.
