Job description

Job Title: Systems EngineerJob Description

We are seeking a Systems Engineer to support a family of Battle Management System (BMS) projects, with a primary focus on applying Model Based Systems Engineering (MBSE) principles and tools to the design, development, and delivery of tactical fire control systems. This role bridges systems-level architecture and software implementation, ensuring technical coherence across hardware and software boundaries. You will collaborate closely with customers, end-users, and cross-functional engineering teams to develop system models, define and decompose requirements, and support integration and verification activities throughout the system lifecycle. The ideal candidate combines strong MBSE tooling expertise with solid software engineering practices, and is comfortable developing rigorous SysML/UML models, participating in software architecture discussions, defining and analyzing message standards and interface control documents (ICDs), and supporting software integration from a systems engineering perspective. This position is based in Dahlgren, VA.

Responsibilities

• Develop requirements for weapon systems integrated with air, land, and sea platforms.

• Execute systems engineering best practices for requirements definition and decomposition, and for the design and implementation of customer and end-user requirements.

• Assess operational performance criteria and provide recommendations for improving system performance.

• Develop and communicate system plans, progress updates, and performance results clearly in both oral and written form.

• Develop Model Based Systems Engineering models for assigned projects and actively contribute to the BMS MBSE Community of Practice.

• Develop, maintain, and evolve system models using MBSE tools such as Cameo Systems Modeler and MagicDraw.

• Create system architecture models, including block definition diagrams (BDDs), internal block diagrams (IBDs), activity diagrams, sequence diagrams, and state machines.

• Trace system requirements, perform functional decompositions, and define logical and physical architectures within the model environment.

• Ensure end-to-end traceability from mission needs through system requirements, design artifacts, and verification evidence.

• Generate documentation and views from system models to support program milestones and systems engineering technical reviews.

• Develop solutions for software-centric projects, incorporating hardware considerations where necessary, including concepts and requirements for graphical user interfaces.

• Collaborate closely with software developers, hardware engineers, test teams, configuration management, training, and safety personnel to maintain technical coherence across the full system lifecycle.

Essential Skills

• Bachelor of Science (BS) degree in a STEM field from an accredited college or university in an engineering, scientific, or technical discipline, or equivalent experience such as direct hands-on experience with a weapon system application in a similar role.

• Minimum of three (3) years of full-time professional experience in systems engineering, including at least one (1) year of experience in software-centric systems engineering.

• Proficiency in Model Based Systems Engineering (MBSE) principles and tools, with a strong preference for candidates with approximately three (3) years of experience in an applied MBSE position.

• Demonstrated experience using MBSE tools such as Cameo Systems Modeler, MagicDraw, IBM Rhapsody, MATLAB/Simulink, or equivalent to create and maintain system models.

• Demonstrated experience developing SysML models, including requirements diagrams, block definition diagrams (BDDs), internal block diagrams (IBDs), activity diagrams, and sequence diagrams.

• Knowledge of weapon systems, command and control systems, and rapid acquisition processes is desired.

• Strong verbal and written communication skills, with the ability to present complex technical material to diverse audiences.

• Ability to work both independently and collaboratively in a fast-paced, dynamic environment.

• Technical proficiency in relevant languages and tools such as Python, C++, and Java.

• Ability to define and analyze message standards and interface control documents (ICDs) and support software integration from a systems engineering perspective.

Additional Skills & Qualifications

• Five (5)+ years of experience in systems engineering or closely related roles.

• Experience integrating artificial intelligence (AI) capabilities within MBSE environments.

• Master’s degree in Systems Engineering, Computer Science, or a related technical field.

• Familiarity with digital engineering concepts, including digital thread and digital twin.

• Experience with requirements management tools such as DOORS, JAMA, or Jira.

• Certification in a relevant Systems Modeling Language (SysML), such as OMG SysML Model User or Model Builder, is desired.

• Certification from INCOSE, such as Certified Systems Engineering Professional (CSEP) or Associate Systems Engineering Professional (ASEP), is a plus.

• Experience contributing to an MBSE community of practice or similar collaborative engineering forums.

• Interest in supporting long-term, growth-oriented programs with a strong track record of success and continuity.
