Freelance Mechanical CAD & Simulation Engineer - AI Trainer

Help train and evaluate AI agents that work inside a real CAD environment on long engineering tasks—work that would take an expert 10–15 hours. You’ll design part geometry, build reference solutions, and judge the agent’s attempts. You’ll work alongside CFD engineers who simulate the geometry you build.

Requirements

• A degree in mechanical or aerospace engineering, or a related field. A master’s or PhD is a plus.
• Five or more years of professional, hands-on CAD modeling experience with CATIA, SolidWorks, Siemens NX, Creo, or similar. Experience preparing geometry for simulation using ANSYS or similar software is a strong plus.
• An active professional CAD license of your own (required).
• Comfort with Python and GitHub.
• English proficiency at B2 level or above.

Project time expectations

During active phases, tasks are estimated to require around 10–20 hours per week, depending on project requirements. This is an estimate, not a guaranteed workload, and applies only while the project is active.

Compensation

Contributors can earn up to $37 per hour equivalent on this project, depending on their level and pace of contribution.

Compensation varies across projects depending on scope, complexity, and required expertise. Other projects may offer different earning levels based on their requirements.
