Overview

As a Staff Software Engineer in the Unified Compute team, you will own low-level systems powering scientific workloads in the cloud. You’ll shape the architecture of Fusion, Fusion Snapshots, Ignite, and Sched, influencing how compute is managed across multi-cloud environments. You’ll write robust Go and C code close to the OS, optimize performance, and ensure reliable operation in production. You’ll mentor teammates and set high standards for testing and observability, while collaborating with cross-functional teams to enable scalable, fault-tolerant cloud workflows.
