Senior Software Engineer (Cluster Orchestration)

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

As a Senior Software Engineer I (IC3), you will own multiple services within the orchestration platform

You’ll lead design/code reviews, decompose projects into milestones, and drive measurable improvements in reliability and performance

You’ll define SLIs/SLOs for your services, strengthen operational practices, and mentor IC1/IC2 engineers

Your work will ensure customers see consistent improvements in throughput, latency, and system resilience- Familiarity with observability stacks (Prometheus, Grafana, OpenTelemetry)

Strong coding in Go (Python or C++ a plus) with solid CS fundamentals

Hands-on experience running Kubernetes at production scale

~3–5 years of professional software engineering experience building distributed systems or cloud services

Proven ability to improve service reliability and performance using metrics (P95/P99 latency, throughput, error budgets)

Exposure to reliability practices including SLOs, alarms, and post-incident reviews

Knowledge of scheduling concepts like quota enforcement, pre-emption, and scaling strategies

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
