AI Trainer / RLHF Specialist
Growingoperations
AI Trainers and RLHF Specialists are the human evaluators who shape how AI models behave by rating, ranking, and writing preference data that feeds into reinforcement learning from human feedback pipelines. They assess model outputs for accuracy, helpfulness, safety, and adherence to guidelines across diverse topics. Many specialists bring deep domain expertise in fields like medicine, law, or coding, which allows them to evaluate model performance in specialized areas.
Salary by Level
A Day in This Role
The queue is the work. Model output comparisons, one after another, scored against a rubric that asks which response is more helpful, more accurate, safer. Midday usually brings a calibration session with other trainers to argue through the tricky edge cases and align on the gray ones. Late in the day, the work shifts mode entirely: writing demonstration data that shows the model how an expert would actually answer a hard question.
Common Interview Topics
- 01You're comparing two model responses to a medical question, one is more thorough but slightly inaccurate, the other is brief but correct. How do you rank them and why?
- 02Describe your process for identifying subtle hallucinations in a model response about a topic you're not deeply expert in
- 03How do you maintain consistent evaluation quality after reviewing 200+ response pairs in a single day?
- 04Walk through how you would write a high-quality demonstration response for a complex multi-step reasoning question
- 05A model response is technically correct but could be misused, describe your framework for evaluating safety versus helpfulness trade-offs
