In short
This remote freelance role at micro1 is about helping train next-generation AI systems with your software skills. You will create coding challenges for AI and judge whether its solutions are right.

- Write automated checks that accept sound solutions and reject wrong ones.
- Choose your own working days and hours, weekends included if you like.
What you need to apply
- Strong backend experience in languages such as Java, Node.js, Go, Rust, Typescript, Python or C++.
- A record of building scalable services and APIs.
- Comfort with debugging, performance work and automated testing.
- Good code review skills; a strong testing background is a big plus.
Who can apply
Anyone in any country can apply, because no country restriction is stated and the role is open worldwide. It is a freelance contract paid from 30 to 100 USD per hour, with 300 openings.
My tip
Pay depends on finished tasks that meet the project specs, so we suggest reading the requirements closely and aiming for complete, careful work from your first task. Complete the screening questions and the roughly 30-minute AI interview on your own, since outside help is not allowed.
