Leidos is seeking a Senior Network Engineer specializing in routing and switching to engineer, implement, and sustain enterprise network infrastructure across a large, distributed environment. The role carries hands-on responsibility for the routed and switched core — designing changes, implementing them cleanly, and resolving the complex problems that reach the senior engineering tier.
This position supports overall network engineering across a broad range of efforts, including planning, designing, and evaluating components of the network. Duties include developing specifications for routing and switching designs, evaluating and recommending technologies to enhance current capabilities, performing needs assessments, and performing installation, modification, testing, and servicing of network equipment.
The successful candidate operates independently on complex engineering work, translates requirements into implementable designs, and serves as an escalation point for routing, switching, and transport issues that others cannot resolve.
Impact: Contributes to the completion of significant project milestones and recommends technical solutions and improvements that affect program results. Work is performed under general direction, with latitude for independent judgment on technical approach.
Complexity: Resolves complex technical problems requiring in-depth analysis, evaluation of multiple factors, and application of established engineering principles and best practices.
Communication: Communicates technical information, design recommendations, risks, and status to engineering leadership, peer teams, and stakeholders. Explains complex technical concepts clearly to both technical and non-technical audiences.
Knowledge: Strong working knowledge of routing and switching principles, theories, and concepts, with demonstrated depth across enterprise network technologies.
Develop and maintain engineering and operational documentation, including:
This role is for an engineer who is genuinely hands-on. The expectation is not oversight of someone else's configuration work but direct ownership of the design, the change, the validation, and the outcome.
The successful engineer is the person others escalate to — comfortable reading a routing table and a packet capture under time pressure, and equally comfortable writing the implementation plan that keeps the change from becoming an incident.

We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 — and moving faster than anyone else dares.
