Job Description:
Systems Engineer II - Model-Based Systems Engineering (MBSE)
Parsons is looking for a Systems Engineer (MBSE) to join our team in Dahlgren, VA! In this role you will join the fight at an exciting time when naval surface weapons are needed as much as ever. New and emerging threats continue to present challenges that we meet with novel approaches to combat adapting enemy tactics. At Dahlgren, we are working to bring new technology to the Warfighter, continuously improve system performance, and ensure the US Navy maintains the solutions required for ship self-defense while bringing the means to project force.
Project Background
Parsons is providing support to the Gun Weapon System (GWS) program, specifically within the MK 160 Gun Computer System (GCS). This USN Program of Record provides the fire control solution and gun mount control to accurately aim and fire the naval surface guns aboard multiple classes of ships in the fleet. GWS with GCS is integrated as a certified element of the AEGIS Combat System. Our system engineers bring critical skills to support the development, test, integration, and deployment of in-service systems.
Position Summary
We are seeking a motivated and technically capable Systems Engineer to support the modernization of a fielded Program of Record through the application of Model-Based Systems Engineering (MBSE) practices. The successful candidate will work within a System-of-Systems (SoS) environment that integrates legacy software, existing operational capabilities, external platforms, sensors, and emerging mission requirements.
A primary focus of this role is developing and maintaining MBSE artifacts that enable understanding, analysis, and modernization of a legacy Ada-based software architecture as it transitions toward a modular Java-based architecture. The engineer will use MBSE methods and tools to document system behavior, interfaces, dependencies, functional decomposition, and software architecture, providing a foundation for software refactoring, modularization, maintainability improvements, and rapid integration of new sensor capabilities.
The position requires close collaboration with systems engineers, software architects, software developers, test engineers, and platform engineering teams to ensure models accurately represent the current and future-state architecture and support engineering decision-making throughout the modernization effort.
MBSE and Architecture Development
Develop, maintain, and refine MBSE models representing system, subsystem, and software architecture within a System-of-Systems environment.
Create and manage architecture products using SysML and related modeling methodologies.
Use Cameo Systems Modeler to capture:
Operational concepts
System requirements
Functional architectures
Logical architectures
Interface definitions
Software component relationships
Data flows and dependencies
Establish traceability between requirements, functions, software components, interfaces, and verification activities.
Support development of digital engineering artifacts that communicate architecture and design intent across engineering disciplines.
Software Modernization Support
Analyze and model existing legacy software architectures and dependencies to support migration from Ada to Java.
Work with software architects and development teams to represent current-state ("as-is") and future-state ("to-be") software architectures.
Model software services, modules, interfaces, data exchanges, and architectural patterns that promote:
Increased modularity
Reduced coupling
Improved maintainability
Reuse of software components
Easier integration of new capabilities
Support identification of opportunities for service decomposition, abstraction layers, and interface standardization.
Develop architecture views that help software teams understand impacts of modernization decisions and code refactoring activities.
Support Platform Modeling and Digital Engineering
