Senior Model-Based Systems Engineer

Location: Lexington Park, MD

Work Location: onsite

• Build and maintain SysML models using Dassault Systèmes Cameo Systems Modeler/MagicDraw and Teamwork Cloud.
• Translate engineering inputs—including requirements, physical parameters, interfaces, behaviors, and constraints—into standardized system models.
• Develop and maintain SysML block definition, internal block, activity, state machine, requirement, and parametric diagrams.
• Apply sound systems engineering and modeling principles to ensure the Systems Engineering Model (SEM) remains accurate, consistent, and useful as the program's authoritative technical baseline.
• Work within established MBSE modeling standards, architecture patterns, package structures, and configuration-management practices.
• Use JIRA-driven Developmental Change Management (DCM) processes to manage model updates, reviews, pull requests, and configuration changes.
• Collaborate with Digital Environment Leads and engineering teams to connect model elements with external engineering tools and applications, including CATIA, PLM, and simulation/analysis environments.
• Help establish and maintain digital threads between requirements, architecture, design, analysis, verification, validation, and sustainment data.
• Participate in Agile engineering sprints alongside Lead Systems Engineers, technical specialists, government stakeholders, and industry partners.
• Support continuous verification and validation (VV&A) by developing and linking digital test cases in Cameo to system requirements and model elements.
• Develop SysML parametric models that incorporate reliability, maintainability, and supportability calculations and enable automated lifecycle metrics such as MTBF and maintenance man-hours (MMH).
• Prepare and present models during technical working groups, engineering reviews, and digital design reviews.
• Maintain model configuration integrity within Teamwork Cloud, including model access, merges, branching, and conflict resolution.
• Help evolve the program's Digital Engineering Environment and modeling practices as mission and engineering needs mature.
• Work in a Linux-based environment as part of a collaborative Agile engineering team.

• Top Secret/SCI eligible security clearance.
• Master's degree in a technical or scientific discipline; or
• Bachelor's degree in a technical or scientific discipline from an accredited institution with an additional four years of recent, relevant experience.
• 4 years of recent, relevant systems engineering experience involving Model-Based Engineering, Model-Based Systems Engineering, or Digital Engineering.
• Hands-on experience with Dassault Systèmes Cameo Systems Modeler/MagicDraw and Teamwork Cloud.
• Strong understanding of SysML syntax, modeling concepts, and systems architecture/ontology development.
• Experience working in an Agile/Scrum/Kanban environment and familiarity with tools such as JIRA and Confluence.
• A solid foundation in one or more engineering disciplines, such as aerospace, mechanical, electrical, software, or systems engineering.
• Ability to translate real-world engineering requirements, interfaces, behaviors, and constraints into well-structured digital models.
• Strong written and verbal communication skills and the ability to collaborate effectively across multidisciplinary engineering teams.
• U.S. citizenship.

• Experience supporting U.S. Navy, Department of Defense, or aerospace/defense acquisition programs.
• Experience working in a Digital Engineering Environment (DEE) or model-centric acquisition environment.
• Experience developing or maintaining a Systems Engineering Model (SEM) or Technical Baseline Framework (TBF).
• Experience integrating MBSE models with PLM, CAD, simulation, analysis, or other engineering applications.
• Experience with requirements traceability, digital verification and validation, and digital test case development.
• Experience developing SysML parametric models for reliability, maintainability, logistics, or lifecycle analysis.
• Familiarity with configuration management, model governance, model reviews, and collaborative model development.
• Experience supporting complex aircraft or rotorcraft systems.
