German Localization & AI Evaluation Specialist

About OpenTrain

OpenTrain is the #1 platform for finding and building careers in AI training and data labeling. We help specialists turn language and evaluation skills into a durable freelance career by providing work, tracking, and a unified AI training portfolio.

As the hiring organization for this role, OpenTrain connects your localization expertise directly to real AI training tasks that shape model behavior while helping you grow a visible record of your work.

About AI training and localization work

AI training (data labeling/annotation) is the human side of building intelligent systems: people prepare, review, and judge examples that models learn from. Localization and linguistic QA play a central role when models generate language for specific locales and cultures.

This work is remote, flexible, and accessible: many projects require language skill, editorial judgment, and attention to detail rather than prior AI engineering experience. Contributors influence how state-of-the-art systems behave in real-world languages and contexts.

The role

OpenTrain is recruiting German AI localization and evaluation experts to review AI-generated responses, produce model answers in German when needed, and judge accuracy, reasoning quality, and cultural fit for the Germany locale.

This is an hourly contractor, part-time role for Germany-based candidates only. Work typically requires 20+ hours/week and pays up to $50/hour. There are 100 total openings.

• Employment type: Contractor, Part-time
• Location requirement: Germany-based candidates only
• Time commitment: 20+ hours/week
• Pay: Up to $50.00 USD per hour

What you'll do

Apply senior German localization judgment across diverse prompts and use cases to improve model outputs and training data.

Work tasks blend editorial duties (translation, localization, QA) with model-evaluation tasks (rating, comparison, and writing model solutions).

• Review AI responses for accuracy, clarity, adherence to prompts, and logical reasoning.
• Generate German-language model answers and exemplar solutions when required.
• Assess mistakes in method, terminology, tone, and cultural nuance for Germany locale.
• Fact-check references, units, names, dates, and other localized details.
• Compare and score multiple AI responses on correctness and reasoning quality.
