The Digital Modernization Sector at Leidos has an opening for a Design Engineer (Campus Area Network/Local Area Network (CAN/LAN)) to support our government customer's global enterprise networks. The CAN/LAN service network architecture provides solutions for modernizing network components while supporting service delivery for customer requirements in a mission-focused operational enterprise. Our team is completely replacing a global enterprise network while providing design, engineering, and transition for a wide range of customer network requirements.

Hands-on experience implementing and troubleshooting standard routing protocols in a production network, such as Open Shortest Path First (OSPF) or Border Gateway Protocol (BGP)
Hands-on experience implementing and troubleshooting standard switching and trunking protocols in a production network, such as Virtual Local Area Networks (VLANs), 802.1q, and port-channels.
Preferred Qualifications:
Network engineering and design experience specific to CAN/LAN. Experience should include application of industry standards, developing configurations, and integration of solutions into production environments.
Network engineering and design experience with MPLS WANs, network management tools, and firewalls.
