Job Description:

Parsons is looking for a Systems Engineer (MBSE) to join our team in Dahlgren, VA! Parsons is providing support to the Gun Weapon System (GWS) program, specifically within the MK 160 Gun Computer System (GCS). 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.

* Work is on-site at NSWC Dahlgren in King George, VA.
* The Systems Engineer will support the modernization of a fielded Program of Record through the application of Model-Based Systems Engineering (MBSE) practices. Work is performed within a System-of-Systems (SoS) environment that integrates legacy software, existing operational capabilities, external platforms, sensors, and emerging mission requirements. Your primary focus 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 role will collaborate with engineers, software architects, developers, 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 Facilitate architecture reviews, model walkthroughs, and technical working groups.

Translate complex software architecture concepts into understandable model views for both technical and non-technical stakeholders.

Support requirements analysis, trade studies, modernization planning, and technical baseline reviews.

Provide MBSE guidance and support to software development teams and other engineering disciplines.
