Germany-Based English & German AI Generalist Trainer 2026 May

Rexzone is hiring Germany-based AI Generalist Trainers to support RLHF and large language model evaluation by assessing, ranking, and QA-checking model outputs to strengthen training data quality and drive model performance improvement in bilingual (English/German) AI workflows.

About the Role

As a Germany-based English & German AI Generalist Trainer at Rexzone, you will evaluate and improve LLM behavior through RLHF-style tasks such as ranking responses, verifying factuality, checking instruction-following, and writing clear rationales. You will apply annotation guidelines compliance to produce consistent judgments that improve training data quality, reduce ambiguity, and support model performance improvement across real-world use cases.

What You Will Do

You will review model-generated outputs in English and German, perform large language model evaluation, and deliver high-quality feedback. Your work includes evaluation, ranking, QA evaluation, and validation of responses against task rubrics, content policies, and style requirements, ensuring training data quality for downstream model training and prompt evaluation.

Why This Role Matters

Your decisions directly impact training data quality and help improve model performance improvement outcomes. By providing reliable rankings and well-structured reasoning, you enable better reward modeling and RLHF pipelines, strengthen QA evaluation signals, and increase consistency in multilingual model behavior.

How We Work

This is a remote, full-time role for candidates based in Germany. You will work with standardized annotation guidelines, participate in calibration sessions, and collaborate asynchronously to maintain high agreement and clear documentation. Rexzone values careful reasoning, annotation guidelines compliance, and measurable quality improvements through validation and QA.
