About the Role

We are seeking a Staff Software Engineer to own the design, development, and long-term health of systems that automate our global GPU cloud network. This role focuses on building production software, setting technical direction, and improving the quality bar for the team, requiring a solid understanding of networking fundamentals and expertise in software development.

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.
  • 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.
  • Successful applicants offered employment with CoreWeave will be required to complete a basic criminal record check, conducted in compliance with GDPR.
  • This position requires access to export controlled information. Applicant must be a U.S. person or eligible to access export controlled information without required authorization or obtain necessary authorization.
