Staff Software Engineer (Network Development)

About this role

• CoreWeave runs one of the largest GPU clouds in the world, and the network underneath it has to be fast, reliable, and almost entirely self-operating. Our Network Development team builds the software that makes that possible
• We design, build, and run the platforms and services that provision, configure, automate, monitor, and heal the network, so that the people relying on it rarely have to think about it
• We are looking for a Staff Software Engineer to take ownership of these systems
• This is a software engineering role at its core
• You will spend most of your time designing and writing production software, setting technical direction, and raising the quality bar for the team
• A solid understanding of networking fundamentals is required, but deep network engineering expertise is not
• This role is about building the software that operates the network
• Own the design, development, and long-term health of the platforms and services that automate the network, including config generation, device provisioning, workflow automation, observability tooling, and internal CLIs and APIs
• Plan and map out complex projects months in advance, sequencing the work, anticipating dependencies, and keeping several efforts moving in parallel
• Lead technical direction through RFCs, design reviews, and architecture decisions, and break ambiguous problems down into shippable work
• Write well-tested, well-documented software in Python and Go, and set the standard for quality across the team through strong test cases, clear error handling, and solid CI/CD practices
• Improve the reliability and operability of what we run by defining service-level indicators and objectives and relentlessly reducing manual toil through automation
• Partner closely with Network Engineering, Observability, Fleet Engineering, and HPC teams so our automation fits cleanly into the wider system
• Join the on-call rotation once you are ramped, and help drive calm, blameless follow-up when things break
