JavaScript Developer (AI Training)
About The Role
What if your JavaScript expertise could directly shape how AI writes and understands code for millions of developers around the world? We're looking for experienced JavaScript developers to evaluate and improve AI-generated code — ensuring it's correct, efficient, and written to the standards real engineers expect.
This is a fully remote, flexible contract role. No AI background needed — just deep JavaScript knowledge and a sharp eye for code quality.
