About the Role

As an AI Generalist Trainer at Rexzone, you will evaluate and improve AI systems by reviewing model-generated responses in English and German. Your work supports RLHF pipelines, large language model evaluation, and training data quality initiatives. You will rank outputs, identify safety and policy risks, validate reasoning, and document decisions using annotation guidelines compliance to enable measurable model performance improvement.

What You Will Do

You will perform prompt evaluation and QA evaluation across multiple domains, comparing model answers for helpfulness, correctness, and safety. You will provide written rationales that explain ranking decisions, verify factual claims when required, and flag inconsistencies to improve training data quality. You will also follow detailed annotation guidelines, apply content safety labeling, and contribute to calibration activities to keep evaluations consistent.

Pay, Schedule, and Location

This is a full-time, fully remote role for candidates based in Germany. Compensation is $35–$40 USD per hour, depending on assessment results and project needs. You will collaborate asynchronously with global teams and meet quality targets tied to training data quality and large language model evaluation outcomes.
