Remote Bilingual German STEM Expert - AI Trainer

Overview

Mercor is seeking a Bilingual German STEM Expert who is native to Switzerland (German-speaking), Germany, or Austria
, with experience in biology / physics / chemistry theory and problem-solving, to develop and refine high-quality reasoning questions that evaluate AI models. Your expertise in biology / physics / chemistry will ensure the scientific accuracy, rigor, and instructional quality of these assessment items. You will create and evaluate German/English prompts and responses, ensuring scientific precision while maintaining clear, natural German phrasing consistent with academic conventions in Switzerland (German-speaking), Germany, or Austria, and alignment with English where needed.

• Design and Optimize STEM-Based Prompts (Bilingual) – Create detailed prompts in German and/or English with multiple constraints and scientifically accurate instructions.
• Define and Document Evaluation Standards – Establish high-level expectations for correct responses in STEM contexts, and develop comprehensive rubrics that account for scientific rigor and—when written in German—linguistic clarity, regionally appropriate terminology (Switzerland [German-speaking], Germany, or Austria usage), and academic tone.
• Conduct Model Testing and Grading (Bilingual) – Run prompts through AI models and assess preliminary outputs against expectations for scientific accuracy, reasoning quality, and clarity. Compare German and English responses where needed.
• Support Benchmarking and Quality Assurance – Collaborate in QA review processes to ensure prompt tasks and rubrics meet scientific standards. Maintain consistency and reliability across German-language benchmarks prior to integration into official evaluation sets.

• Native-level fluency in German (written), specifically native to Switzerland (German-speaking), Germany, or Austria
• Strong reading and writing proficiency in English
• BS or BA in Biology / Physics / Chemistry
• Familiarity with undergraduate-level biology / physics / chemistry topics
• Strong writing and critical thinking skills
• Ability to work independently and meet deadlines

• 2+ years of experience in teaching, research, or an applied STEM discipline field
• Experience working with German-language STEM curricula or academic standards in Switzerland, Germany, or Austria

• Complete a short AI-led interview (approximately 15 minutes)
• Then, if selected, you will be invited to work on the project.
