- Create Golden Sets: Write "ideal" human-generated responses to serve as Ground Truth for automated testing and fine-tuning.
- Maintain Guidelines: Develop and update the Annotation Rubric-the detailed instructions that define exactly what counts as a "correct" or "safe" response.
Skills:Must-Haves- Linguistic Precision: Exceptional command of English grammar and semantics. You can spot the difference between "good" and "great" writing instantly.
- Experience with LLMs: Familiarity with GPT-4, Claude, or similar models, including their limitations (hallucinations, bias).
- Extreme Attention to Detail: Ability to perform repetitive data review tasks without losing focus or consistency.
Nice-to-Haves- Annotation Experience: Prior experience with RLHF, data labeling platforms (like Scale AI, Labelbox), or QA roles.
