Job summary

CoreWeave is the Essential Cloud for AI and a Living Wage accredited employer. We are seeking a Staff Software Engineer, Runtime Systems to design and build the execution layer that enables AI, simulation, and engineering workloads to run reliably at scale.

You will shape abstractions between workloads and execution environments, implement production-grade runtime components, and collaborate with platform and infrastructure teams to deliver reliable, observable systems across Kubernetes-based

Qualifications

• Significant experience building complex systems software, distributed infrastructure, runtimes, workflow systems, or adjacent technology.
• Strong software engineering fundamentals and production coding ability.
• Experience designing APIs, protocols, schemas, or contracts between independently evolving systems.
• Strong understanding of distributed‑system failure modes, state, authority, retries, concurrency, and side effects.
• Strong communication skills and experience influencing architectural decisions across teams.

Responsibilities

• Design and build runtime components for complex AI, simulation, and engineering workloads.
• Define abstractions for workloads, execution environments, dependencies, state, capabilities, and failure.
• Design interfaces between higher‑level services and systems such as Kubernetes, Argo, and OSMO.
• Establish clear boundaries around which systems own state, decisions, and side effects.
• Build adapters and integrations for heterogeneous execution environments.
• Diagnose behaviour across application, orchestration, cluster, and infrastructure boundaries.
• Improve the reliability, observability, and debuggability of distributed workload execution.
• Work closely with Go, Kubernetes, and infrastructure engineers to turn architecture into production systems.
