Job description

Are you an experienced Luxembourgish language professional eager to shape the future of AI? Large-scale language models are evolving rapidly, moving beyond simple chatbots into powerful engines of learning, communication, and cultural understanding. With high-quality training data, tomorrow’s AI can deliver more natural, accurate, and contextually rich Luxembourgish experiences across education, accessibility, and global communication. That training data begins with you—your expertise will help power the next generation of AI.

We’re looking for a highly skilled Luxembourgish language specialist who can bring linguistic depth, cultural context, and precision to training data. You’ll work with cutting-edge AI tools, evaluate and refine Luxembourgish text outputs, and provide expert feedback on grammar, syntax, semantics, style, and cultural appropriateness to strengthen model performance.

On a typical day, you will review and annotate Luxembourgish content, assess AI-generated outputs for accuracy and fluency, identify and document error patterns, and collaborate with our team to refine prompts, evaluation methods, and linguistic guidelines.

Fluency in Luxembourgish is required, along with demonstrated experience in translation, linguistics, language teaching, editing, or related professional work. Experience in training, coaching, or linguistic annotation is a plus. Clear communication skills, cultural knowledge, and attention to detail are essential.

We offer a pay range of $8 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 stable internet connection; company-sponsored benefits such as health insurance and PTO do not apply.
