Experts / Train AI / Coding
Engineers who train coding models.
Software engineers who write, review and test code tasks and agent runs for frontier models.
What software engineers do.
Each one writes production code for a living and is AI-interviewed in their stack.
Write
Realistic coding tasks with reference solutions and tests.
Review
Rank and correct model code on correctness and style.
Verify
Run agent trajectories and check results with tests.
Red-team
Find insecure or broken code before your users do.
Specialities: Python · TypeScript · Java · Go · Rust · C++ · SQL · Infrastructure
Sample coding tasks.
Multi-step tasks, checked end to end
An engineer writes a realistic task in a real repository, runs the agent, and verifies the result with tests rather than by eye.
- Tasks built in real environments
- Pass/fail checked by tests
- Trajectory reviewed step by step
The CSV export times out for accounts with more than 50,000 rows. Make it stream the file instead, and keep the current column order.
1. Found export handler · 2. Replaced in-memory build with a streamed writer · 3. Added a test with 60,000 rows
All 214 tests pass, including the new one. Column order unchanged. Memory stays flat.
Questions
Anything else? Talk to us and a specialist will reply.
How do you check software engineers' expertise?
Each expert passes a 10-minute AI interview in coding, and a senior expert in the same field reviews their score before they work on any task.
Can we choose the sub-specialities and languages?
Yes. Tell us the sub-specialities, languages and countries you need, and we recruit and calibrate experts to match before the pilot.
How is our data protected?
Project data stays in an isolated workspace, is encrypted at rest and in transit, and is never used to train other models.
I work in coding. How do I join?
Apply with the short form on our Find work page. You take one AI interview in coding, and we match you to projects that fit your expertise and hours.
How much does the work pay?
Rates depend on the project and your level. You see the rate before you accept any work.
