Systems Engineer for Advanced Battle Management System

SAIC is seeking a talented and mission-driven Senior Systems Engineer (ET1233) to support the Advanced Battle Management System (ABMS) Digital Infrastructure (DI) Network Designer & Deployer program in support of the Department of the Air Force (DAF) Program Executive Officer for Command, Control, Communications and Battle Management (PEO C3BM). 

The ABMS DI Network is the backbone of the DAF BATTLE NETWORK — the Air Force's contribution to the DoD's Combined Joint All-Domain Command and Control (CJADC2) warfighting concept. This program is delivering a secure, resilient, multi-enclave digital infrastructure spanning Unclassified through TS/SCI security domains, integrating cutting-edge commercial and government technologies including cloud computing, SD-WAN, Enterprise Cross Domain Solutions, Data Distribution Networks, Scalable Transport, and Data Link Integration Modules across global operational sites. 

As a Senior Systems Engineer, you will serve as a key technical contributor within the ABMS DI Network System of Systems engineering team — translating government requirements into actionable designs, supporting work package development, and ensuring the seamless integration of DI Network foundational features across all security enclaves and operational environments. Your engineering expertise will directly shape the network infrastructure that enables warfighters to make faster, better-informed decisions across every domain of modern conflict. 

Positions are available in Reston, VA and San Diego, CA.
