  • Providing technical leadership within your area of expertise

What We're Looking For

  • 7+ years of network engineering experience
  • Strong experience with Juniper networking technologies preferred
  • Cisco networking experience also considered
  • Experience designing, implementing and maintaining enterprise networks
  • Strong knowledge of TCP/IP networking and associated protocols
  • Experience with routing protocols including OSPF, EIGRP and BGP
  • Experience with LAN, WAN and network security technologies
  • Experience with firewalls, ACLs and secure network architectures
  • Excellent troubleshooting and problem-solving skills
  • Strong communication skills and ability to work within highly collaborative engineering teams

Desirable Experience

  • EVPN, VXLAN or MPLS environments
  • Multicast networking
  • VLANs, trunking and spanning tree
