Sr. Systems Engineer (MBSE)

CACI International•Aberdeen Proving Ground, MD

7d•$126,100 - $277,300•Onsite

About The Position

Lead systems engineering efforts for Department of Defense intelligence, electronic warfare, and cyber systems. As a Senior Systems Engineer, you will lead Model-Based Systems Engineering (MBSE) initiatives to establish and maintain digital engineering baselines for intelligence, EW, and cyber systems. You will develop and manage Department of Defense Architecture Framework (DoDAF) artifacts and system views to support program architecture decisions, and ensure Modular Open Systems Approach (MOSA) compliance across defense systems and programs. Additionally, you will develop product roadmaps and technology insertion strategies for next-generation C5ISR capabilities, and provide System-of-Systems (SoS) engineering leadership to establish technical baselines and architectural direction. You will interface with government program offices and other defense contractors on complex system integration efforts.
