About AI training work

AI training (data labeling / human feedback) is the human side of building modern AI. Contributors prepare and evaluate examples—text, code, audio, or simulations—that models learn from, often on flexible, remote schedules.

This project focuses on mechanical-engineering content: you’ll craft rigorous engineering problems and verified Python solutions that teach models to reason about simulations, multi-step calculations, and analysis workflows.

The role

We’re hiring Mechanical Engineering AI Trainers to produce and evaluate computationally intensive engineering problems and verified Python-based solutions. Work centers on creating accurate, reproducible multi-step calculations and numerical workflows that models will learn from and be evaluated against.

• Contract, part-time role: less than 20 hours per week.
• Work type: creating problem prompts, writing Python solutions, and evaluating model outputs (evaluation rating / RLHF tasks).
• Expected domains: thermodynamics, fluid mechanics, heat transfer, solid mechanics, dynamics & vibrations, mechanical design, manufacturing, and CAE/FEA/CFD concepts.

What you'll do

• Design multi-step engineering problems suitable for model training and evaluation.
• Implement verified Python solutions and reproducible scripts (NumPy/SciPy/pandas or similar) for numerical methods, iteration, or simulation workflows.
• Provide clear explanations, intermediate steps, and verification for each solution so model reviewers can evaluate correctness.
• Evaluate model responses and rate outputs per provided guidelines (EVALUATION_RATING and RLHF tasks).
• Optionally reference CAE/FEA/CFD workflows or simulation concepts when relevant, without requiring licensed software output.

Requirements

• Education: BSc in a relevant field plus 1+ year relevant experience OR an MSc/PhD in a relevant field (mechanical, aerospace, materials, mechatronics, manufacturing, energy systems, engineering physics, applied math, computational mechanics).
• Experience (if BSc): 1+ year in mechanical/aerospace engineering practice or research (design, analysis, R&D, manufacturing, simulations, or academic research).
• Preferred experience: 3+ years professional experience in thermodynamics, fluids, heat transfer, solid mechanics, dynamics/vibrations, mechanical design, manufacturing, CAD/CAE, FEA, CFD, or thermal systems.
• Python (required): demonstrable experience using Python for engineering/scientific computing (e.g., NumPy/SciPy/pandas; numerical methods; simulation or optimization scripts).
• English (required): Advanced English (C1). Proof via test score, English-taught degree, or evidence of advanced English use in professional/academic work.
• Nice to have: exposure to CAE/FEA/CFD tools (ANSYS, Abaqus, COMSOL, OpenFOAM), MATLAB/Simulink, or progress toward professional licensure (PE/Chartered).
