Staff Software Engineer, Network Development

CoreWeave is The Essential Cloud for AI. Built for pioneers by pioneers, CoreWeave delivers a platform of technology, tools, and teams that enables innovators to build and scale AI with confidence.

We are looking for a Staff Software Engineer to take ownership of the systems that automate our network. 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.

Responsibilities:

• 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.

Requirements:

• 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.
• 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.

Benefits:

• Medical, dental, and vision insurance - 100% paid for by CoreWeave
• Company-paid Life Insurance
• Voluntary supplemental life insurance
• Short and long-term disability insurance
• Flexible Spending Account
• Health Savings Account
• Tuition Reimbursement
