Backend Engineer, Part-Time AI Task Creation and Evaluation - Remote (India)

• $30–$100 per hour
• 100% remote
• Part-time
• 20 or more hours a week, you choose when

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

The AI systems everyone is talking about are trained and tested by real engineers. The teams building them need backend engineers who can create realistic feature and bug-fix tasks, judge the code an AI produces, write the solution a strong engineer would deliver, and explain exactly 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 realistic backend coding tasks for feature development and software bug fixes
• Build reliable checks that accept valid implementations and reject incorrect or incomplete solutions
• Review AI-generated backend code for correctness and maintainability
• Assess debugging work, performance improvements and automated tests

Why this is worth your time

• Get paid $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 backend engineers will not have for years
• Build a career edge for what comes next: AI is reshaping backend engineering, and the engineers who understand it from the inside will lead that change
• Fully remote and flexible, no fixed shifts, no commute

Who this is for

• Professional backend development experience with Java, Node.js, Go, Rust, TypeScript, Python, C++ or a similar language
• Experience building scalable services and APIs
• Clear written and spoken English for analytical, problem-solving and technical communication
• No AI experience needed. You bring the expertise; we bring the training on the tools.

Pay and details

• $30–$100 per hour, paid hourly as an independent contractor
• 20 or more hours a week, you choose when; fully remote, India
