Senior Site Reliability Engineer

We're the San Francisco Compute Company. We're building the first real-time trading platform for compute. Everyone from startups to enterprises to research labs and individuals can buy and sell compute, from 1 to 1000+ nodes for an hour to over a year. With our liquid market to resell unused compute hours, buyers no longer need to worry about contract lock-in and providers have less idle nodes. Over the next decade, we anticipate thousands of enterprises, governments, startups, and labs will be training and serving large models, and we’re building a team to scale our market.

About the Role

ML training clusters are some of the most high performance computers on the planet. Even relatively small clusters would have been in the TOP500 5 years ago. Our supercomputing team is responsible for keeping our compute clusters running smoothly, monitoring hardware health, and fixing things when they go wrong. We believe strongly in automation — code is the only reliable way to manage hardware at scale. As we scale, this will become a more data-driven role, predicting failures before they happen. We’re a small team, so you’ll be spending time talking to customers as well.

• You appreciate and value good documentation

• You have experience provisioning and managing Kubernetes clusters
