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 Staff Software Engineer (IC5), 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-organizational initiatives in scheduling, multi-tenant quota enforcement, and hyperscale scaling. This high-impact role requires you to establish organization-wide best practices for platform reliability and observability, resolve complex distributed bottlenecks under intense demand, and mentor senior engineers across teams to elevate engineering standards.
Who You Are
- 8–12 years of professional software engineering experience.
- Advanced software development proficiency in Go and strong distributed systems design principles.
- Proven track record designing, operating, and scaling large-scale distributed systems in production environments.
- 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 organizational operational standards.
Preferred
- Familiarity with modern orchestration, workflow, and mesh technologies such as 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. Here are a few qualities we've found compatible with our team. If some of this describes you, we'd love to talk.
- 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.
