Job Description

Our customer, Defense Information Systems Agency (DISA), requires personnel to support the Defense Enclave Services (DES) contract. The DES team is responsible for developing and deploying operational capabilities into an integrated and modernized enterprise environment. Become a member of the team supporting an extensive modernization program critical to DISA and Fourth Estate Agencies. Fourth Estate entities include organizations within the DoD that are not in the military departments, IC agencies, or combatant commands.

The DES contract unifies the DOD Fourth Estate Defense Agencies and Field Activities (DAFA) common-use information technology systems, personnel, functions, and program elements under the direction of DISA’s Fourth Estate Network Optimization program office.

Our client 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.
