STEM Experts - PhD - AI Training - Germany

About Prolific

Prolific is not just another player in the AI space – we are building the biggest pool of quality human data in the world.

The role

We're looking for experts who hold PhDs in STEM subjects to help train and evaluate cutting‑edge AI models. For this project we are seeking experts in subjects like Computer Science, Statistics, Mechanical Engineering, Maths, Physics, and more who are comfortable narrating their approach to solving complex problems.

If you have the necessary experience, we'll send you a quick test to assess your skills and suitability for AI tasks. If successful, you’ll be invited to join Prolific as a Domain Expert where you’ll get paid to train and evaluate powerful AI models.

Researchers looking for your skills tend to pay up to $150/hr per AI task completed. You must be prepared to complete paid tasks that require one hour of uninterrupted work, though many are shorter.

What you’ll bring

• A PhD (or PhD candidacy) in a STEM field – including Statistics, AI/ML, Computer Science, Mechanical Engineering, Mathematics, Physics, or a related discipline
• Strong subject matter expertise and ability to work through complex, technical problems
• Experience with or a strong interest in AI and machine learning is a bonus
• Willingness to narrate your thinking out loud
• Strong attention to detail
• Reliable, fast internet connection and access to a computer
• A PayPal account to receive payments from our clients

What you’ll be doing in the role

• Working through complex STEM problems and tasks while narrating your reasoning process out loud
• Screen‑recording your approach to problems and tasks
• Reviewing and evaluating AI‑generated responses to technical problems, rating them for accuracy, depth, and reasoning quality
• Comparing multiple model answers and selecting/justifying the best response
• Writing improved exemplars, rationales, or structured feedback when models fall short
