Technical Experts needed to stump AI Models
About the role
Company Description
This enterprise client helps the world’s most innovative companies improve their AI models by providing human feedback.
Job Description
Help build a benchmark of real, expert-level problems that today’s best AI agents still can’t solve. Experts take a genuinely hard problem from their own field and turn it into a task an AI must solve from scratch in a Linux terminal.
The goal: stump the model. A task counts only if, when three frontier AI models each try it three times, they mostly fail. It’s not annotation - contributors design the problems that expose where AI still breaks.
Who we need
- Masters degree or higher
- 10+ years of professional experience in a technical domain
- At least one publication (academic or professional)
Domains in demand
- Coding
- Machine Learning
- Systems
- Security
- Hardware
Additional Information
- This is an ongoing project - at least 7 weeks
- Onboarding process is approximately 90 minutes total
