Prolific is not just another player in the AI space – we are building the biggest pool of quality human data in the world.
Over 35,000 AI developers, researchers, and organizations use Prolific to gather data from paid study participants with a wide variety of experiences, knowledge, and skills.
The role
We're looking for CompSci experts to help train and evaluate cutting-edge AI models. For this project we are seeking PhD holders 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 Computer Science 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 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
