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

The AI systems everyone is talking about are trained and tested by real experts. The teams building them need mechanical engineers who can help create realistic examples, judge how well an AI understands what is happening, describe the expert view clearly, and explain where the AI misses important details. Your judgment helps models learn how objects move, how parts interact, and how physical tasks unfold. This is that work, done remotely around your current job.

What you'll do

- Review footage of robots, machines, tools and mechanical systems, identifying the objects and physical interactions shown
- Annotate movements, component positions and task sequences so AI systems can learn how mechanical work unfolds
- Review annotations against project standards for accuracy, consistency and completeness
- Identify unclear or incorrect annotations and explain what needs to change in difficult video examples

Why this is worth your time
- Get paid $50–$90 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 and flexible, no fixed shifts, no commute

Who this is for

- Experience in mechanical engineering, mechanical design, manufacturing, robotics or a related field, with at least two years in the field
- A practical grasp of how mechanical parts, tools, machines and physical systems move and interact
- Robust written English, close attention to detail, and the ability to work independently while maintaining accuracy and consistency
- No AI experience needed. You bring the expertise; we bring the training on the tools.

Pay and details

- $50–$90 per hour, paid hourly as an independent contractor
- 20 or more hours a week, you choose when; fully remote, India

How to apply

- Apply on OpenTrain (about two minutes; upload your resume).
- Complete a short application on the hiring platform.
- If shortlisted, take a short AI interview. Most people hear back within days.
