About The Company
Invisible Technologies makes AI work. Our platform cleans, labels, and structures company data so it’s ready for AI. It adapts models to each business and adds human expertise when needed — the same approach used to improve models for over 80% of the world’s top AI companies, including Microsoft, AWS, and Cohere. Our successes span industries — from supply chain automation for Swiss Gear, to AI-enabled naval simulations with SAIC, and validating NBA draft picks for the Charlotte Hornets. Invisible, profitable for over half a decade, reached $134m in revenue and ranked #2 fastest-growing AI company in 2024, and recently raised $100M to advance its platform technology.
About the Role

Are you a fluent German speaker eager to shape the future of AI? Large-scale language models are evolving from clever chatbots into powerful engines of linguistic and cultural understanding. With high-quality training data, tomorrow’s AI can democratize education, accelerate research, and support global communication across languages and contexts. That training data begins with you—we need your expertise to help power the next generation of AI.

We’re looking for German speakers who understand the nuances of grammar, usage, spelling, tone, and cultural context in both formal and informal German. You’ll challenge advanced AI models with linguistic edge cases, cultural subtleties, translation ambiguities, and phrasing differences—documenting model failures and guiding improvements with clarity and precision.

On a typical day, you will engage in text-based conversations with the model, evaluate its responses for accuracy and fluency, annotate linguistic patterns, test comprehension across a range of German language inputs, and suggest refinements to prompts and evaluation methods.

A background in linguistics, translation, writing, localization, or teaching is ideal. Experience with German language instruction, editing, or QA is a strong signal of fit. Clear communication and a reflective approach to language—explaining not just what is correct, but why—is essential.

Ready to turn your German fluency into the foundation for tomorrow’s AI? Apply today and help train the model that will teach the world.

We offer a pay range of $6-to- $65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above. As a contractor you’ll supply a secure computer and high‑speed internet; company‑sponsored benefits such as health insurance and PTO do not apply.
