Job description

• $50-100 per hour equivalent, paid per accepted task
• Under 20 hours a week, you choose when

Work on the cutting edge of AI coding systems, on your own schedule, and get paid for the full-stack engineering skills you already have.

The AI systems changing how software gets built are trained and tested by real engineers. The teams building them need full-stack engineers who can create realistic software tasks, judge whether the AI's code is correct and complete, write the solution a professional engineer would deliver, and explain where the implementation falls short. Your judgment becomes part of how the next generation of AI coding systems works. This is that work, done remotely around your current job.

What you'll do

• Create and solve realistic full-stack tasks involving user-facing features and APIs
• Write professional reference solutions and validate code across front-end and back-end systems
• Review AI-generated code for security, performance and maintainability, and explain where it needs improvement

Why this is worth your time

• Get paid the equivalent of $50-100 an hour to build real AI skills, on top of your current job
• Work directly with frontier AI coding tools and see how they are built, tested and improved, experience most software engineers will not have for years
• Build a career edge for what comes next: AI is reshaping software engineering, and the engineers who understand it from the inside will lead that change
• Fully remote, fully flexible, no minimum shift, no commute

Who this is for

• Fluent in English; experience contributing to complete software-system architecture, working in unfamiliar codebases, and solving difficult debugging problems
• No experience in AI training work needed. You bring the expertise; we bring the training on the tools.

Pay and details

• $50-100 per hour equivalent; pay is per accepted task, as an independent contractor
• Under 20 hours a week, you choose when; fully remote, United States
