Senior Staff Infrastructure Engineer – Kubernetes Platform

About the company

Our mission is simple: deliver seamless, secure, reliable, and resilient AI compute at scale. We've built a versatile cloud platform that eliminates infrastructure barriers, empowering builders to focus on innovation instead of fighting their stack. Because breakthrough AI should move at the speed of ideas, not infrastructure.

About the Role

We’re looking for a Kubernetes Platform Staff Infrastructure Engineer to join our team during an exciting phase of growth.
