The AI infrastructure behind those clusters determines how workloads are placed, how resources are shared, and how reliably systems perform under constant pressure.</p> <p>As a Principal Engineer in AI Infrastructure, you will lead the design and evolution of the cluster orchestration systems that make this possible. This includes Slurm, Kubernetes, SUNK, and the control planes that support AI training, inference, and model onboarding at scale.</p> <p>You will define long-term architecture, solve hard scaling problems, and set technical direction across teams. Your work will directly affect how quickly customers can run models, how efficiently we use GPUs, and how reliably the platform behaves at scale.</p> <h2><span style="font-size: 14pt;"><strong>What You’ll Do</strong></span></h2> <h3><strong>Architecture and Technical Direction</strong></h3> <ul> <li>Define the long-term architecture for CoreWeave’s orchestration platforms across Kubernetes, Slurm, SUNK, Kueue, and related systems.</li> <li>Act as a technical authority on scheduling, quota enforcement, fairness, pre-emption, and multi-tenant GPU isolation.</li> <li>Make design decisions that balance performance, reliability, cost, and operational complexity.</li> </ul> <h3><strong>Orchestration Platform Development</strong></h3> <ul> <li>Lead the evolution of Kubernetes-native control planes, including SUNK and custom operators.</li> <li>Design systems that support workload admission, validation, and rollout, including model onboarding flows.</li> <li>Identify and remove scaling limits across schedulers, control planes, registries, networking, and storage.</li> </ul> <h3><strong>Reliability and Operations</strong></h3> <ul> <li>Set standards for reliability, observability, and operational readiness across orchestration services.</li> <li>Define SLOs, alerting, and incident response practices for platform-critical systems.</li> <li>Ensure systems behave predictably during failures, peak load, and rapid growth.</li> </ul> <h3><strong>Hands-on Engineering</strong></h3> <ul> <li>Write and review production code for Kubernetes controllers, schedulers, admission logic, and internal tooling.</li> <li>Measure and improve scheduling latency, container startup time, image distribution, and cold-start performance.</li> <li>Lead architecture and design reviews across infrastructure teams.</li> </ul> <h3><strong>Leadership and Influence</strong></h3> <ul> <li>Mentor senior and staff engineers and help grow technical leaders.</li> <li>Influence platform, infrastructure, security, and product teams through clear technical judgment.</li> <li>Engage with customers and open-source communities on deep technical topics when needed.</li> </ul> <h2><span style="font-size: 14pt;"><strong>Who You Are</strong></span></h2> <ul> <li>15+ years of experience building and operating large-scale distributed systems ...
