Germany-Based English & German AI Generalist Trainer 2026 May

Rexzone is hiring Germany-based, remote, full-time AI Generalist Trainers to support large language model evaluation through RLHF-style ranking, LLM evaluation, and training data quality improvements. You will assess model outputs in English and German, apply annotation guidelines compliance, perform QA evaluation, and write clear rationales that drive model performance improvement in real-world AI/LLM workflows.

About the Role

As a Germany-based English & German AI Generalist Trainer at Rexzone, you will evaluate, rank, and validate model-generated responses to improve large language model evaluation outcomes. Your work will focus on RLHF-aligned judgments, prompt evaluation, and training data quality, ensuring annotation guidelines compliance and consistent QA evaluation across English and German datasets.

What You Will Do

You will review model outputs, compare alternatives, and provide reasoning-backed feedback that helps optimize model behavior. This includes content safety labeling when required, careful adherence to rubrics, and structured validation checks so the resulting training signals support measurable model performance improvement.

Why This Role Matters

Your evaluations become training signals that influence how models respond in production. By maintaining high training data quality and consistent annotation guidelines compliance, you help reduce error patterns, improve instruction-following, and increase reliability across English and German user scenarios.
