Core Weave's Cluster Orchestration team builds and operates the Kubernetes-native foundation that powers AI training and inference  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.

As a Software Engineer, Cluster Orch (SUNK), you will act as a principal technical leader shaping the long-term architecture and strategy for Core Weave'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.

• 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.

• 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).

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.

At Core Weave, we work hard, have fun, and move fast! We're in an exciting stage of hyper-growth that you will not want to miss out on. We're not afraid…
