Northrop Grumman Aeronautics Systems has an opening for a Principal Systems Architect Engineer to join our team of qualified, diverse individuals within our Systems Engineering organization. This role is located in Melbourne, FL.

In this role, you will support model based systems engineering, requirements development, and architecture definition for a complex aerospace system. This role focuses on using Cameo to capture and manage system requirements, functional and physical architectures, and interfaces across the program lifecycle.

You will work under general direction to develop and maintain system models in Cameo, applying a complete understanding and wide application of systems engineering and MBSE principles. You'll also support project leadership in shaping the system architecture, ensuring requirements and interfaces are well defined, traceable, and aligned with program objectives.

Responsibilities

• Support requirements development, decomposition, allocation, and traceability within Cameo, translating customer and stakeholder needs into system, segment, and subsystem requirements.
• Develop and maintain system architectures (operational, functional, and physical) using SysML and MBSE methods (e.g., use case, activity, sequence, block definition, and internal block diagrams).
• Integrate requirements, behaviors, interfaces, and constraints into a coherent model that supports mission analysis, system design, and verification/validation planning.
• Apply established modeling conventions and guidelines; recommend improvements to enhance consistency and usability of the system model.
• Coordinate updates to requirements and architecture with multi disciplinary teams (mission systems, avionics, ground systems, communications, vehicle teams, etc.).
• Generate model based views and reports to support technical reviews (SRR, PDR, CDR, etc.), communicating requirements coverage and architecture status.
• Collaborate with requirements management and configuration management to help baseline the Cameo model and maintain alignment with tools such as DOORS/DOORS Next.
• Provide MBSE and Cameo support and informal mentoring to engineers contributing to the model.

Basic Qualifications

• Must have a Bachelors of Science degree in a STEM field and at least 5 years of relevant military / professional experience, OR a Master's Degree in a STEM field and at least 3 years of relevant military / professional experience, OR a PhD and at least 1 year of relevant military / professional / academic experience
• Must have an active US Government Secret or higher clearance (with a background investigation completed within the last 6 years or currently enrolled into Continuous Evaluation).
• Must have systems engineering experience with emphasis on requirements development, decomposition, and architecture definition for complex systems.
• Must have direct experience using Cameo/MagicDraw (or equivalent MBSE tool) for SysML based modeling at the system or subsystem level.
• Must have experience to providing technical solutions to a wide range of complex, difficult problems that are consistent with organizational objectives.

Preferred Qualifications

• Experience supporting mission planning or ground systems, including participation in defining operational concepts, workflows, or interfaces between air vehicle and ground mission systems.
• Experience with air vehicle or mission system requirements, including performance, avionics, mission, or integration requirements, and capturing those requirements in an MBSE/Cameo model.
• Exposure to mission systems and communications architectures, such as data links, networks, and interfaces between onboard systems, ground segments, and external assets.
• Experience applying MBSE/SysML to represent mission threads or operational scenarios that span vehicle, mission systems, and ground systems.
• Experience integrating Cameo models with requirements management tools (e.g., DOORS/DOORS Next) or generating basic traceability and coverage reports.
• Prior experience supporting design reviews with model based artifacts on defense or aerospace programs.
