About the Role

We are seeking a talented and experienced Senior Software Engineer to join our Network Development Team. In this role, you will 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.

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.
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.
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.
Experience with infrastructure automation tooling such as Ansible and Jinja.
Experience with a source-of-truth or IPAM and DCIM system such as NetBox.
Experience with 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.
Successful applicants offered employment with CoreWeave will be required to complete a basic criminal record check, conducted in compliance with GDPR.
