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 Senior Infoblox DDI Engineer to engineer, implement, migrate, and sustain enterprise DNS, DHCP, and IP address management (DDI) services in support of large-scale network operations. The engineer will provide hands‑on technical leadership for Infoblox grid infrastructure, DNS, DHCP, IPAM, and associated network services, including design, migration, troubleshooting, testing, security hardening, and production implementation. The position also requires strong routing and switching expertise because DDI services depend on the underlying network for reachability, DHCP relay, segmentation, routing, and high availability.

The engineer must be able to troubleshoot issues across both the Infoblox platform and the network infrastructure supporting it.
