Senior Software Engineer, Cluster Orch (SUNK)

What You'll Do:

CoreWeave’s Cluster Orchestration team builds and operates the Kubernetes-native foundation that powers AI training and inference at scale. We eliminate infrastructure bottlenecks and create next-generation orchestration capabilities—including SUNK (Slurm on Kubernetes) and beyond—ensuring demanding workloads run seamlessly, reliably, and efficiently across massive GPU clusters.

About the role:

As a Software Engineer, Cluster Orch (SUNK), you will act as a principal technical leader shaping the long-term architecture and strategy for CoreWeave’s orchestration platform. You will define the technical direction, own critical components of our orchestration layers and managed services, and drive major cross-organisational initiatives in scheduling, multi-tenant quota enforcement, and hyperscale scaling. In this high-impact role, you will establish organisation-wide best practices for platform reliability and observability, resolve complex distributed bottlenecks under intense demand, and mentor senior engineers across teams to elevate technical standards.

Who You Are:

• Bachelor’s degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience).
• 8+ years of professional software engineering experience with a proven track record of designing, operating, and scaling large-scale distributed systems in production environments.
• Advanced software development proficiency in Go and strong distributed systems design principles.
• Deep technical expertise in Kubernetes internals, Slurm schedulers, or cloud-native development.
• Demonstrated experience setting technical direction and successfully influencing cross-team architecture and platform goals.
• Proven ability to mentor senior engineers, review complex technical designs, and elevate organisational operational standards.

Preferred:

• Familiarity with modern orchestration, workflow, and mesh technologies (e.g., Ray, Kubeflow, Kueue, Istio, Knative, or Argo Workflows).
• Deep experience with distributed workloads, GPU-based cloud applications, or machine learning pipelines.
• Strong structural knowledge of advanced scheduling concepts, including quota enforcement, resource pre-emption, and intelligent scaling strategies.
• Practical exposure to enterprise reliability practices, including defining SLOs, telemetry monitoring, and leading post-incident reviews.
• Direct exposure to large-scale AI infrastructure workloads (ML training, inference, or high-performance computing).

Wondering if you're a good fit?

We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams—even if you aren't a 100% skill or experience match.

• You love to: Define the long-term architecture for cloud platform systems operating at global hyperscale.
• You're curious about: Pioneering orchestration beyond SUNK and uncovering novel ways to evolve platforms for next-generation AI workloads.
• You're an expert in: Mentorship, technical leadership, and solving structural issues that balance infrastructure cost, performance, and reliability.
