About the Role

As a Germany-based English/German AI Generalist Trainer at Rexzone, you will evaluate and improve AI systems by reviewing model-generated responses, ranking alternatives, and writing concise reasoning. Your work will directly influence training data quality, large language model evaluation results, and model performance improvement through consistent RLHF and quality assurance processes.

What You Will Do

You will complete prompt evaluation, response ranking, and QA evaluation tasks in bilingual (English and German) settings. You will validate outputs against annotation guidelines compliance, flag content safety labeling issues, and document decisions with clear, evidence-based rationales to support training data quality and reliable large language model evaluation.

How Success Is Measured

Success is measured by accuracy and consistency in evaluation and ranking, high adherence to annotation guidelines compliance, strong reasoning quality, low rework rates in QA, and dependable throughput. Your decisions should improve training data quality and contribute to model performance improvement across multiple domains.

Work Setup

This is a remote, full-time role for candidates based in Germany. You will collaborate asynchronously with Rexzone teams, complete assigned evaluation batches, and participate in calibration sessions to maintain consistent large language model evaluation and QA standards.

How to Apply

Apply to Rexzone with a brief summary of your bilingual (English/German) experience, your Germany location, and examples that demonstrate analytical skills and attention to detail. Selected candidates will complete a skills assessment focused on prompt evaluation, ranking, validation, and rationale writing.
