Principal Network Engineer - Routing & Switching

Leidos is seeking a Principal Network Engineer specializing in routing and switching to serve as the senior technical authority for the routed and switched enterprise. The role is responsible for advancing network innovation through the execution of strategic design and implementation efforts that improve the security, scalability, resiliency, and performance of the enterprise network.

This position is responsible for overall network engineering support across a broad range of efforts, including planning, designing, and evaluating the various components of the network. Duties include providing specifications for network architecture, evaluating and recommending new technologies to enhance current capabilities, performing needs assessments, and directing the installation, modification, testing, and servicing of network infrastructure.

The successful candidate sets technical direction for routing and switching across the enterprise — defining standards, resolving the architecture questions no one else can, and directing the work of other engineers against designs they own.

Scope and Impact Impact: Influences development of solutions that impact strategic project and program goals and business results. Recommends and develops new technical solutions, products, and standards. Leads and manages the work of other technical staff that has significant impact on project results and outputs.

Complexity: Resolves highly complex problems through significant application of technical knowledge, conceptualization, reasoning, and interpretation. Develops solutions that are highly innovative and achieved through research and integration of best practices.

Communication: Communicates with executive and client leadership on matters of significant technical importance. Presents architecture recommendations, implementation plans, risks, dependencies, and status to technical leadership, stakeholders, and approval boards, and works to build consensus around new concepts, practices, and approaches.

Knowledge: In-depth understanding of network engineering principles, theories, and concepts and their application across a range of programs. Serves as a subject matter expert within the routing and switching domain.

Primary Responsibilities Architecture and Design Authority

• Own the enterprise routing and switching architecture, including core, distribution, access, WAN edge, and data center interconnect designs.

• Define routing architecture and policy standards across BGP, OSPF, EIGRP, and static routing, including addressing strategy, route filtering and summarization, path selection, redistribution boundaries, and convergence targets.

• Define Layer 2 and high-availability architecture, including VLAN and spanning-tree strategy, link aggregation, redundancy models, VRF and segmentation structure, multicast design, and QoS policy architecture.
