Germany-Based English & German AI Generalist Trainer 2026 May

Rexzone is hiring Germany-based, bilingual (English/German) AI Generalist Trainers to support AI/LLM workflows through RLHF, large language model evaluation, and training data quality work that drives model performance improvement. You will evaluate, rank, and QA model-generated outputs, write clear rationales, and ensure annotation guidelines compliance across tasks such as prompt evaluation, content safety labeling, and validation. This role is remote and full-time, focused on improving training data quality and consistent evaluation standards for reliable model performance improvement in production LLM systems.

About the Role

As an AI Generalist Trainer at Rexzone, you will assess and improve model behavior by evaluating and ranking model outputs in English and German. Your work directly supports RLHF pipelines, large language model evaluation, and training data quality initiatives, including QA evaluation, prompt evaluation, and annotation guidelines compliance. You will document reasoning, validate edge cases, and collaborate with operations to keep labeling quality high and consistent.

What You Will Do

You will complete structured evaluation tasks, compare multiple responses, apply rubrics and annotation guidelines, and provide concise rationales that help improve model performance. You will also perform validation and QA checks to maintain training data quality, flag unsafe or policy-violating content in content safety labeling workflows, and escalate recurring issues that impact evaluation consistency.

Compensation and Work Setup

Remote, full-time role for candidates based in Germany. Pay range is $35–$40 per hour, depending on demonstrated evaluation accuracy and QA performance. You will work within defined task queues, meet throughput and quality targets, and follow secure handling and confidentiality requirements for model and dataset materials.
