Staff Software Engineer, Cluster Orch (SUNK)

About the role As part of the Cluster Orchestration team, you will play a key role in advancing CoreWeave’s orchestration platform, including SUNK (Slurm on Kubernetes) and beyond, our Kubernetes-native foundation that powers AI training and inference at scale. This is an opportunity to help shape one of the most critical layers of the AI cloud: ensuring workloads run seamlessly, reliably, and efficiently across massive GPU clusters. By building the systems that eliminate infrastructure bottlenecks and create new orchestration capabilities, you will directly empower customers to innovate faster and push the boundaries of what’s possible with AI. What You’ll Do As a Staff Engineer (IC5), you will be a technical leader shaping the long‑term strategy for CoreWeave’s orchestration platform. You’ll define the architectural direction, own critical parts of the platform and other managed services, and drive cross‑org initiatives in scheduling, quota enforcement, and scaling at hyperscale. You’ll mentor senior engineers, establish organization‑wide best practices in reliability and observability, and ensure CoreWeave’s orchestration layer evolves to meet the demands of next‑generation AI workloads. Who You Are 8–12 years of professional software engineering experience. Proven track record designing and operating large‑scale distributed systems in production. Deep expertise in Slurm/Kubernetes internals and cloud‑native development. Advanced proficiency in Go and distributed systems design. Experience setting technical direction and influencing cross‑team architecture. Ability to mentor senior engineers and elevate organizational standards. Preferred Familiarity with orchestration and workflow technologies such as Ray, Kubeflow, Kueue, Istio, Knative, or Argo Workflows. Experience with distributed workloads, GPU‑based applications, or ML pipelines. Knowledge of scheduling concepts like quota enforcement, pre‑emption, and scaling strategies. Exposure to reliability practices including SLOs, alarms, and post‑incident reviews. Experience with AI infrastructure and workloads (ML training, inference, or HPC). Wondering if you’re a good fit? You love defining long‑term architecture for systems at global scale. You’re curious about orchestration beyond SUNK and how to evolve it for next‑generation AI. You’re an expert at mentorship, architecture, and operational excellence across teams. You thrive on solving problems that balance cost, performance, and reliability in high‑demand environments.
