What this actually is
You review AI-generated code, rank model outputs against each other, write prompts that test edge cases, and provide expert feedback that gets used to train coding models. Not shipping production software. The platform title (Senior Software Engineer) reflects the rate band and the expertise required, not the day-to-day work.
