Generalist AI Trainer at AI Startup
Lightly AG is a Zurich-based AI company and ETH/HSG spin-off, backed by Y Combinator and top-tier investors. Our machine learning and computer vision technology is trusted by global leaders in autonomous driving, medical imaging, and visual inspection.
As we push the boundaries of what AI can do, we need sharp, curious people to help us make it better. We're looking for Generalist AI Trainers to join us on a part-time contractor basis — no technical background required, just strong judgment, clear thinking, and an eye for quality.
The minimum expected time commitment is 10 hours/week.

Follow detailed instructions to complete structured evaluation tasks
Flag problematic or incorrect outputs and explain what's wrong and why
Occasionally research topics to verify whether AI responses are factually sound
