Polished Snow, Palo Alto, California
A Research Engineer, ML Infrastructure who thinks from first principles and builds things that work outside the lab. You care about why people want something and why models behave the way they do, and you care that what we ship works when it actually matters. If you have built products, shipped software, talked to customers or run outreach, and you are drawn to the hardest reliability problems in AI, this is the role.
This is a role for someone early in their career who has already built real things. We care more about how fast you have been learning than where you have been.
We want to work with people who want to be among the best in the world at what they do. If that sounds like you, we want to hear from you.
Send us your best work. Tell us about the coolest thing you have built end to end and what you learned fastest in the last year. Add your X and your website if you have them.
Polished Snow is an AI lab building energy-based reasoning models for critical systems. Power grids, industrial infrastructure, the technology the world runs on.
Most AI models are built to generate a plausible answer. Our model, Case, is built to know when an answer is wrong before it becomes one. It scores, refines and verifies a plan against the full system until it holds. That difference matters enormously when the cost of being wrong is high.
We are a small, funded team and we are just getting started.
We are a small team with a high bar and very little process. You get a real problem and the trust to go after it, and you decide how it gets solved. We think carefully and move fast.
When you build something here, you own it. The system, the results, and what happens when it breaks. Nobody else is going to pick it up for you.
