  • Troubleshoot complex issues across routing, switching, firewalling, and wireless (overlay + underlay)
  • Set technical direction for network operations and reliability
  • Automate away toil using Linux-based tooling and infrastructure-as-code
  • Operate in a 24/7 environment supporting global, business-critical infrastructure
  • Work across a multi-vendor environment (Arista, Cisco, Palo Alto, F5, NetScaler, Mist, Aruba, InfiniBand, and more)
  • Collaborate on next-gen initiatives , including wireless design and AI / HPC cluster deployments

What We’re Looking For:

  • 10+ years hands-on network engineering experience in production environments

Deep expertise in:

  • Routing & switching
  • Firewalling & segmentation
  • Wireless networking
  • Strong overlay / underlay troubleshooting skills
  • Solid Linux / Unix experience
  • Proven experience leading major incidents
  • Comfortable working independently and mentoring others
