CoreWeave's data center network engineering team in Warsaw needs a senior network engineer to design, deploy and run large-scale data center fabrics. The work covers spine-leaf/Clos fabrics across multiple sites, rack layout and cabling planning, configuration generation and deployment with automation, and validation before traffic reaches production. Troubleshooting spans BGP routing policy, ECMP and packet loss, and optics. The posting wants seven or more years in network engineering, BGP, Python scripting, and experience directing data center technicians; mentoring junior engineers and writing runbooks are part of the job.
