  • Strong understanding of core networking protocols (BGP, OSPF, IS-IS, MPLS, TCP/IP, IPv4/IPv6)
  • Proven experience owning and operating critical network infrastructure
  • Strong problem-solving skills and ability to lead through complex technical challenges
  • Participate in an on-call rotation to support production systems
  • Ability and willingness to travel up to 50%, * Experience with high-performance networking technologies such as InfiniBand or RoCE
  • Strong knowledge of VXLAN, EVPN, and modern data center networking architectures
  • Experience with automation and scripting (Python or equivalent)
  • Familiarity with network observability, telemetry, and monitoring systems
  • Experience with network modeling and programmability (YANG, OpenConfig, NETCONF)
  • Experience working with cloud networking and hybrid infrastructure environments
  • Strong communication and collaboration skills, with the ability to influence technical direction, * A technical leader who can design and operate networks at scale
  • A systems thinker who understands the interaction between networking, compute, and applications
