Systems Engineering

Our flexible systems approach to engineering allows us to quickly identify technology gaps and provide solutions that intelligently integrate state-of-the-art technologies with legacy systems.

Our Systems Engineering team leverages a breadth of technical tools to help customers achieve elegant solutions to complex problems. Our approach allows you to innovate within your transport system for critical applications, shifting execution risk away and allowing you to focus on your strategy. As systems and networks increasingly work together and tasks become more complex, the federal government faces daunting new systems engineering challenges. The increasing complexity of today’s defense and security systems and the tasks they must address requires ever more effective systems engineering to meet current and future needs.  Our robust systems engineering processes include the identification and analysis of requirements through the selection and assessment of technology and architecture, analysis and coordination of complex system design, development, execution, and delivery of rigorously tested production systems with a full complement of sustainable hardware and software capability.

We address the full systems engineering needs of the military services and various branches of the intelligence and national security community, including areas as diverse as mission assurance, joint network integration, intelligence, surveillance, and reconnaissance, data and services, operations and intelligence, and command and control. Our customers face unique systems engineering requirements. Their need to connect and integrate systems into a seamless whole has never been greater. We ensure their specific requirements are satisfied and they are positioned to succeed in an ever more complex future.


While innovation is a major focus at Expression Networks, our expertise is based upon recognized professional standards. Our numerous certifications include: The International Council on Systems Engineering (INCOSE) – Certified Systems Engineering Professional (CSEP).
