CFD Engineer — AI Task Designer Remote (OpenFOAM)

Location: Remote

Company

hirify.global develops AI evaluation and research workflows that use domain expertise to teach and assess real-world physical reasoning.

What you will do

• Design compact, self-contained CFD and aerodynamics tasks for evaluating AI engineering reasoning.
• Write precise problem statements covering boundary-condition selection, mesh quality, flow-regime identification, and simulation setup.
• Develop deterministic checkers that automatically evaluate model answers.
• Prepare verified reference solutions to confirm that tasks are solvable and correctly scored.
• Review and iterate on tasks for physical accuracy, clarity, and appropriate difficulty.
• Apply OpenFOAM experience to ground tasks in practical simulation workflows while working independently and asynchronously.

Requirements

• Hands-on experience with OpenFOAM.
• Strong foundation in fluid mechanics, aerodynamics, and heat transfer.
• Experience with mesh generation, turbulence modeling, boundary-condition specification, and post-processing.
• Ability to formulate precise, self-contained, and objectively verifiable engineering problems.
• Strong written communication skills and the ability to explain complex physics clearly and concisely.
• Degree-level background in aerospace engineering, mechanical engineering, or a closely related discipline; BS or higher preferred.

Nice to have

• Experience with multiple CFD solvers or multiphysics platforms.
• Python, Bash, or MATLAB scripting for simulation setup or post-processing.
• Experience with design optimization, flow-control strategies, or adjoint methods.
• Graduate-level coursework or research in aerodynamics, propulsion, or computational methods.
• Experience writing technical assessments, exam problems, or engineering challenges.

Culture & Benefits

• Hourly contract with a commitment of 10–40 hours per week.
• Fully remote and flexible work with an asynchronous schedule.
• Freelance autonomy and task-based work.
• Potential for ongoing work and contract extensions as new projects launch.
• Weekly payouts and a quick screening process.
