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.\nWhat you'll do\nCreate and solve realistic full-stack tasks involving user-facing features and APIs\nTrace requests and data across browsers and back-end services to judge whether an AI implementation works correctly\nWrite professional reference solutions and validate code across front-end and back-end systems\nReview AI-generated code for security, performance and maintainability, and explain where it needs improvement\nWhy this is worth your time\nGet paid the equivalent of $50-$100 an hour to build real AI skills, on top of your current job\nWork directly with frontier AI coding tools and see how they are built, tested and improved, experience most software engineers will not have for years\nBuild 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\nFully remote, fully flexible, no minimum shift, no commute\nWho this is for\nStrong professional experience building production full-stack applications across multiple programming languages\nStrong full-stack systems knowledge covering browser applications, APIs, application state, databases, service integration, architecture and debugging\nFluent in English; experience contributing to complete software-system architecture, working in unfamiliar codebases, and solving difficult debugging problems\nNo experience in AI training work needed.
