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're seeking a talented and experienced Senior Software Engineer to join our Network Development Team. In this role, you'll play a critical part in designing, developing, automating, and maintaining the networking software and infrastructure that powers Core Weave’s GPU cloud.

Your day-to-day will involve writing code, creating configuration templates, designing dashboards, building CLI tools, and working closely with our Network Engineering and Network Observability teams to automate, operate, and monitor Core Weave’s network.

What you'll doOwn 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.

Mentor other engineers, review code and designs, and help grow the technical skills of the team.

Contribute to a positive, collaborative team and organizational culture.
