The Digital Modernization Sector at Leidos has an opening for a Network Engineer (Campus Area Network/Local Area Network (CAN/LAN)) to support 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. This is a unique and rare opportunity to build and transition critical operations to a modern service provider network architecture.

The job duties are as follows:

• Interpret customer requirements and apply standard design approaches for service delivery. • Fully document designs with diagrams, bill of materials, cabling sheets, configurations, and other supporting documents. • Use our private test lab to evaluate new technologies and capabilities, test proposed changes to production networks, and recreate troubleshooting scenarios to support the production enterprise network. • Schedule maintenance windows for migrating user connections from legacy to the modern infrastructure transition services with little to no impact on critical data flows. • Provide technical expertise to Operations engineers and technicians, supporting fault isolation and resolution. • Solve tough problems with innovative and scalable solutions. • Develop secure network designs including configurations that align with Defense Information Security Agency (DISA) Security Technical Implementation Guides (STIGs) and enterprise policies. • Obtain Authority to Operate (ATO) for new devices, software, and capabilities. • Supervise (not manage) other network support specialists to plan, coordinate, and implement network services. • Develop and improve design products, processes, and systems for our team to work efficiently and effectively.

Experience specific to network engineering to include Tier III or higher network operations and/or network design and implementation.

Prior responsibility for production network hardware configurations for Cisco, Brocade, and/or Juniper.

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.

Desired 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.

Expert knowledge of routing and switching protocols and the ability to demonstrate knowledge through briefings and documentation.

Extensive BGP experience a plus.

Cisco Certified Network Professional (CCNP) or equivalent knowledge.

Initiative and disciplined to work unsupervised as part of a network engineering team. Experience establishing process, developing documents, and organizing repositories is a plus.

At Leidos, we outthink, outbuild, and outpace the status quo - because the mission demands it. Were not hiring followers. Were recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. Were already at step 30 - and moving faster than anyone else dares.
