Mission Systems Engineer

MANTECH seeks a motivated, career and customer-oriented Mission Systems Architect to join our team in Stafford, VA . In this role, you will play a key part in supporting Marine Corps mission engineering initiatives by aligning Modeling, Simulation, Analysis, and Wargaming (MS&A) activities with warfighting experimentation and joint interoperability efforts. You will work closely with stakeholders to plan, coordinate, and execute high-impact projects that directly influence operational readiness and decision-making.

Responsibilities include but are not limited to:

• Define and translate mission objectives into system architectures, requirements, and design specifications in alignment with DoDAF/UAF standards.
• Develop mission concepts of operations (CONOPS), operational scenarios, and performance models to ensure comprehensive mission planning and execution.
• Apply Model-Based Systems Engineering (MBSE) methods and tools to generate, maintain, and interpret mission architecture views, ensuring traceability between mission needs and technical solutions.
• Lead integration, verification, and validation efforts to confirm system readiness and mission success across the program lifecycle.
• Collaborate with cross-functional teams and stakeholders-including analysts, warfighters, developers, and subject matter experts-to align mission objectives with system capabilities and drive continuous improvement.

Minimum Qualifications:

• Minimum of 3 years of experience in systems engineering, software development, or related engineering discipline, with exposure to complex military systems and architectures.
• Bachelor's degree in Computer Engineering, Electrical Engineering, Systems Engineering, or a related technical field. Additional 2 years of experience may be substituted in lieu of degree.
• Hands-on experience applying DoDAF and/or UAF for system architecture definition, visualization, and documentation.
• Proficiency with requirements management tools (e.g., DOORS, Jama, Cameo) and model-based systems engineering (MBSE) methodologies, including modeling and simulation tools (e.g., SysML, MATLAB, Simulink).
• Strong communication skills with the ability to convey complex technical concepts clearly across multi-disciplinary teams and stakeholders

Preferred Qualifications:

• Proficiency in one or more programming languages such as C++, Python, or Java.
• Experience with hardware/software integration and familiarity with network architectures and protocols.
• Advanced expertise with modeling and simulation tools and technologies (e.g., Cameo & SysML, MATLAB, Simulink, ExtendSim).
• Demonstrated success operating in fast-paced, multi-disciplinary environments supporting mission-driven objectives

Clearance Requirements:

• This role requires an active DoD TS/SCI Clearance with SAP eligibly.

Physical Requirements:

• The person in this position must be able to remain in a stationary position 50% of the time.
