Backend Engineer, Part-Time AI Coding Task Design - Remote (India)

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

Put your backend engineering skills to work on AI coding systems, on your own schedule, and get paid for the judgment you already use every day.

AI training work is the human side of building AI systems: experienced people create examples, test how a model behaves and review what it produces, so the system becomes more accurate and useful. AI systems that write software need backend engineers who can design realistic coding problems and decide, with precision, whether a solution truly meets the requirements.

What you'll do

• Design realistic backend coding tasks for AI systems: new features to build, defects to debug and bugs to fix
• Write deterministic verifiers that pass every reasonable correct solution and reject the ones that miss the requirements
• Weigh code quality, performance, testing, refactoring, algorithms, data structures and service scalability in each task
• Bring secure coding and security review into a task wherever it matters

Why this is worth your time

• Get paid the equivalent of $30-$100 an hour to assess code quality and verify backend solutions
• Work on AI systems that write backend code, setting the tasks and checks that show whether their solutions really work
• Apply backend and security judgment to coding tasks and verification
• Fully remote and flexible, no fixed shifts, no commute

Who this is for

• Strong backend development experience in a language such as Go, Python, Java, TypeScript, Node.js, Rust or C++
• Experience building scalable APIs and services, implementing complex features, debugging software, resolving bottlenecks and reviewing code
• Strong analytical, problem-solving and technical communication skills
• Professional fluency in English
• Helpful background includes application security, secure coding, vulnerability assessment, penetration testing, OWASP or CWE guidance, security-focused code review and performant software in large codebases
• No AI experience needed.

Pay and details

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