What You'll Do: 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. About the role: 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. - 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. Who You Are: - 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. Preferred: - A degree in Computer Science or a related field is a plus. Wondering if you're a good fit? We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams – even if you aren't a 100% skill or experience match. Here are a few qualities we've found compatible with our team. If some of this describes you, we'd love to talk. - You explain the reasoning behind your technical choices, stay open to being convinced otherwise, and pick the right tool for the job rather than defending a favorite. - You see a problem and solve it without waiting to be asked, and you always look for ways to make things easier, faster, and more secure. - You treat problems as shared problems, keep incident culture blameless, and give credit generously.
