Descrição da oferta de emprego

• $30-$100 per hour equivalent, paid per accepted task
• About 15-20 hours a week, you choose when

Work on the cutting edge of AI coding tools, on your own schedule, and get paid for the backend engineering skills you already have.

The AI coding systems changing how software gets built are trained and tested by real developers. The teams building them need people with backend experience to create realistic feature and bug-fix tasks, judge whether the AI's code works, write the checks that separate correct solutions from incorrect ones, and explain where the solution falls short. Your engineering judgment becomes part of how the next generation of coding systems improves. This is that work, done remotely around your current job.

What you'll do

• Design clear, realistic coding tasks covering feature development, bug fixes and code reasoning
• Write deterministic verifier scripts and automated tests that check whether a solution is correct
• Use backend engineering judgment to evaluate code for debugging, performance and secure coding
• Refine task difficulty and quality so the training data reflects real software work

Why this is worth your time

• Get paid the equivalent of $30-$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 developers will not have for years
• Build a career edge for what comes next: AI is reshaping software engineering, and the developers who understand it from the inside will lead that change
• Fully remote, fully flexible, no minimum shift, no commute

Who this is for

• Strong backend experience in Java, Node.js, Go, Rust, TypeScript, Python, C++ or a similar language, including scalable services and APIs
• Experience with debugging, performance work, automated testing, code review, secure coding and creating clear coding challenges with automated checks
• Clear written and spoken English, with strong problem-solving and technical communication skills
• No AI experience needed. You bring the expertise; we bring the training on the tools.

Pay and details

• $30-$100 per hour equivalent; pay is per accepted task, as an independent contractor
• About 15-20 hours a week, you choose when; fully remote, Brazil
