Northrop Grumman • Melbourne, FL

1d • $122,800 - $184,200 • Onsite

About The Position

Northrop Grumman Aeronautics Systems is hiring a Senior Principal Systems Engineer for its Systems Engineering organization in Melbourne, Florida. The role provides senior technical leadership in model-based systems engineering (MBSE), requirements development, and architecture definition for a complex aerospace system. It focuses on using CAMEO to capture and manage system requirements, functional and physical architectures, and interfaces throughout the program lifecycle.

The engineer leads requirements and architecture development in CAMEO, ensuring the digital system model coherently represents system requirements, behaviors, and interfaces. Under consultative direction, the engineer independently develops approaches to solutions and collaborates with chief engineers, integrated product teams, and specialty disciplines to support design decisions, mission effectiveness, and verification planning. The position requires an active U.S. Government Top Secret clearance. Travel is 10% of the time, and relocation assistance may be available.

Requirements

• Bachelor of Science degree in a STEM field and at least 8 years of relevant military or professional experience; or a master's degree in a STEM field and at least 6 years of relevant experience; or a Ph.D. and at least 4 years of relevant experience.
• Active U.S. Government Top Secret clearance, with a background investigation completed within the last 6 years or current enrollment in Continuous Evaluation.
• Extensive systems engineering experience emphasizing requirements development, decomposition, and architecture definition for complex systems.
• Direct experience using CAMEO, MagicDraw, or an equivalent MBSE tool for SysML-based modeling, including creating and maintaining system-level models.

Nice To Haves

• Ability to critically present technical approaches and findings to customers, engineers, and management across multiple disciplines.
• Experience supporting mission planning and ground systems, including operational concepts, workflows, and interfaces between air vehicles and ground mission systems.
• Experience defining and managing air vehicle performance, mission, avionics, and integration requirements and capturing them in an MBSE/CAMEO model.
• Experience with mission systems and communications architectures, including data links, networks, and interfaces among onboard systems, ground segments, and external assets.
• Proven use of MBSE/SysML to represent mission threads, mission planning workflows, or end-to-end operational scenarios spanning vehicles, mission systems, and ground systems.
• Prior experience as a systems engineering or MBSE lead on a defense or aerospace program involving air vehicles, mission planning, or communications systems.

Responsibilities

• Lead requirements development, decomposition, allocation, and traceability in CAMEO, translating customer and stakeholder needs into system, segment, and subsystem requirements.
• Develop and maintain operational, functional, and physical system architectures using SysML and MBSE methods, including use case, activity, sequence, block definition, and internal block diagrams.
• Integrate requirements, behaviors, interfaces, and constraints into a cohesive model supporting mission analysis, system design, and verification and validation strategies.
• Establish and apply modeling conventions and guidelines, and provide recommendations that influence major program and organizational objectives.
• Coordinate architecture and requirements updates with multidisciplinary teams, capturing cross-discipline impacts and dependencies.
• Generate model-based views and reports for technical reviews such as SRR, PDR, and CDR, communicating requirements coverage, interface definition, and design maturity.
• Provide MBSE and CAMEO guidance and mentorship to engineers and help grow modeling capability across the team.
