Coding Expert - C++
About this role
About the Role We're looking for experienced C++ developers to help evaluate and improve AI systems that write and reason about code. Your expertise will directly shape how AI understands C++ — from low-level memory management to complex systems architecture. This is a fully remote, flexible contract role. Work on your own schedule, on projects that matter. What You'll Do - Review and evaluate AI-generated C++ code for correctness, efficiency, and style - Write robust C++ solutions spanning algorithms, systems programming, game development, and more - Identify edge cases, bugs, and subtle logic errors in AI-generated code - Provide clear, structured feedback and well-reasoned explanations for your evaluations - Create human-readable summaries of solutions and coding decisions - Help define what "good" C++ looks like for the next generation of AI models Who You Are - Proficient in modern C++ (C++11 and above), including STL, OOP, templates, and memory management - Comfortable writing and reviewing code across a range of difficulty levels - Strong communicator — able to explain technical decisions clearly in writing - Detail-oriented with a sharp eye for correctness and performance - Self-motivated and reliable when working independently Nice to Have - 3+ years of experience in C++ domains such as systems programming, game engines, embedded systems, or finance - Bachelor's degree or higher in Computer Science or a related field (or equivalent practical experience) - Familiarity with performance optimization, compiler behavior, concurrency, or metaprogramming - Prior experience with data labeling, RLHF, or AI training workflows Why Join Us - Work on cutting-edge AI projects alongside top research labs and AI teams - Fully remote and asynchronous — work from anywhere, on your own schedule - Freelance perks: autonomy, variety, and the satisfaction of doing technically rigorous work - Your contributions directly improve AI tools used by developers and engineers worldwide - Potential for ongoing work and contract extension based on performance
