Senior Software Engineer, Network Development

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'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 CoreWeave’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 CoreWeave’s network.

What you'll do

• 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.
• 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.

What we're looking for

• 8 or more years of professional software engineering experience, ideally building and operating production infrastructure, platform, or backend systems at scale.
• Strong proficiency in Python and Go
• Solid understanding and experience in CI/CD (testing, code review, maintaining continuous builds and deployments)
• Strong understanding of managing runtime health for services and applications at an enterprise level
• A love of process automation and toil elimination, with hands-on experience building workflow automation or orchestration systems and automated device provisioning at scale such as Zero Touch Provisioning.
• Strong planning skills, including the ability to lay out and drive projects across a multi-month horizon while keeping several concurrent efforts moving as part of a team.
• Strong, well-reasoned technical opinions, paired with genuine openness to better ideas and other people's input.
• A solid understanding of core networking fundamentals, including IP addressing and subnetting, routing/switching, NTP, and DNS.
• Comfort with Linux and Kubernetes, and experience with infrastructure automation tooling such as Ansible and Jinja, a source-of-truth or IPAM and DCIM system such as NetBox, and observability tooling such as Prometheus and Grafana.
• Excellent written communication, a habit of writing documentation other people can actually use, and experience mentoring engineers and collaborating across teams.
• A degree in Computer Science or a related field is a plus.

How we work

We build as a team. The engineers who thrive here explain the reasoning behind their technical choices, stay open to being convinced otherwise, and pick the right tool for the job rather than defending a favorite. They see a problem and solve it without waiting to be asked, and they always look for ways to make things easier, faster, and more secure. We treat problems as shared problems, keep our incident culture blameless, and give each other credit generously. Strong opinions are welcome. Ego is not.

The base salary range for this role is $165,000 to $220,000. The starting salary will be determined based on job-related knowledge, skills, experience, and market location. We strive for both market alignment and internal equity when determining compensation. In addition to base salary, our total rewards package includes a discretionary bonus, equity awards, and a comprehensive benefits program (all based on eligibility).
