- $40–$80 per hour
- 100% remote
- Part-time
- Fully flexible schedule

Work on the cutting edge of AI engineering, on your own schedule, and get paid for the technical judgment you already have.

The AI systems everyone is talking about are trained and tested with carefully prepared examples and reviews from real engineering experts. The teams building them need people who can turn detailed FreeCAD assemblies into precise questions, write the exact answer supported by the design, and record any ambiguity or gap they find. Your judgment helps shape the next generation of AI systems. This is that work, done remotely around your current job.

What you'll do

- Study multi-part assemblies, geometry, assembly relationships and engineering function in FreeCAD designs
- Write several precise technical questions for each assembly, with exact answers that can be checked against the design
- Create clear engineering training material from detailed design information
- Record useful insights and ambiguities, and communicate clearly when clarifying requirements or reviewing feedback

Why this is worth your time
- Get paid $40–$80 an hour to build real AI skills, on top of your current job
- Work directly with frontier AI tools and see how they are built, tested and improved, experience most mechanical engineers will not have for years
- Build a career edge for what comes next:



AI is reshaping mechanical engineering, and the people who understand it from the inside will lead that change
- Fully remote, fully flexible, no minimum shift, no commute

Who this is for

- Extensive knowledge of mechanical engineering, aerospace engineering or industrial design
- Robust foundational CAD knowledge, including multi-part assemblies and engineering drawings, with FreeCAD or comparable CAD experience helpful
- Experience authoring detailed technical questions or engineering training material, clear technical communication, and professional fluency in English
- No AI experience needed. You bring the expertise; we bring the training on the tools.

Pay and details

- $40–$80 per hour, paid hourly as an independent contractor
- Part-time, flexible schedule; fully remote, India
