Systems / Mission Systems Engineer (C5ISR), Network

D9Tech Resources is hiring a network-focused Systems / Mission Systems Engineer (C5ISR) to support cleared Federal and Department of Defense missions, working fully remote within the continental United States. The selected engineer owns outcomes from initial design through long-term sustainment, moving fluidly across systems integration, configuration management, and enterprise network architecture while helping build, secure, and authorize mission systems on AWS and across the broader enterprise. Security and compliance are built in from day one, so RMF and ATO discipline, least privilege, and documented, repeatable delivery all matter here. This billet is filled from D9Tech’s vetted, cleared engineering bench.
