About The Position

CACI is looking for a Sr. Network Engineer to work as part of a collaborative, multidiscipline team in support of U.S. Government and provide technical subject matter expertise in the field of network engineering and communications modeling. This role provides support in the translation of business requirements into telecommunications (e.g., LAN, MAN, WAN, Voice and Video) requirements, designs, and orders. The engineer will understand how overarching INFOSEC and COMSEC security requirements for the Customer network add to the complexity of this position. The role performs a full range of complex network designs encompassing multiple technologies and technology layers (LAN, WAN, OS, IOS, etc.) within a single, enterprise network. The engineer evaluates new network technologies and makes recommendations to project managers regarding the integration of these technologies into the existing network infrastructure. This includes planning new designs and configurations for integration into the enterprise network, using knowledge of performance characteristics and network interconnect points to ensure effective integration and optimal network performance. The position provides engineering and design support for the creation and deployment of communication systems. It involves researching existing technologies and applying COTS/GOTS systems to develop network infrastructure for voice and data systems, using best practice security methodologies, and integrating system design with network architecture to best meet customer requirements. Post-design support includes installation, configuration, and tier III/IV, O&M support for both enterprise and field-deployed systems, including local area network (LAN), wide area network (WAN), and system-level aspects. The role also involves creating simulated networks to test applications over low bandwidth links, troubleshooting network connectivity issues, and installing/configuring wide area links utilizing radio frequency (RF) communications (i.e., over satellite, cell, and microwave). The engineer will configure, test, and maintain network infrastructure that connects to the enterprise architecture and needs knowledge of network intrusion detection.
