Coding models improve only when the tasks and checks used to train them are realistic and sound, so the teams building them need software engineers who can design problems, write verifiers that separate right answers from wrong ones, and explain their reasoning clearly. This is part-time contract work done remotely on a flexible schedule.\nWhat you'll do\nDesign realistic coding tasks around new features, bug fixes, refactoring and performance work\nWrite reference solutions and deterministic verifiers that pass correct answers and reject wrong ones\nProduce code samples, debugging approaches and written technical reasoning, and dig into defects and bottlenecks in varied codebases\nRefactor legacy code for clarity, efficiency and reliability, and review code and submissions from other contributors for accuracy\nWhy this is worth your time\nEarn the equivalent of $50-$100 an hour designing coding tasks, reference solutions and verifiers\nWork on AI coding systems learning to implement features, fix bugs and refactor across many codebases\nApply your software engineering judgment to task design, verifiers and code review\nFully remote and flexible, no fixed shifts, no commute\nWho this is for\nStrong hands-on skill in a language such as Python, Java, Rust, Go, C++ or TypeScript, or a similar one\nBackend experience building scalable services and APIs\nKnowledge of data structures, algorithms, software engineering principles, automated testing and code review\nAble to debug complex systems, fix bugs, improve performance and work in large codebases\nClear technical writing and communication skills, including work in English\nHelpful background includes open source contributions and a public GitHub profile.\nNo AI experience needed. You bring the expertise; your judgment helps improve AI models.\nPay and details\n$50-$100 per hour equivalent; pay is per accepted task, as an independent contractor\nPart-time, flexible schedule; fully remote, United States\nHow to apply\n1.
