About the role

Cornerstone Signals & Cyber Technologies LLC is a certified Small Business, Service-Disabled Veteran-Owned Small Business (SDVOSB), Woman-Owned Small Business (WOSB), and Economically Disadvantaged Woman-Owned Small Business (EDWOSB) providing engineering, technical, advisory, intelligence, and program management services to Federal Government customers.

The Senior Model-Based Systems Engineer (MBSE) will support a Digital Engineering (DE) modernization effort focused on migrating legacy Modeling, Simulation, and Analysis (MS&A) tools, algorithms, applications, and engineering processes into a cloud-native Digital Engineering pipeline.

Responsibilities

• Scope the effort required to represent existing missile engineering data within a SysML-based MBSE environment.
• Develop, update, and maintain complete end-to-end missile system models using SysML.
• Create reusable SysML model libraries supporting Digital Engineering initiatives.
• Develop scalable and repeatable workflows for generating new missile system models.
• Apply, test, validate, and refine MBSE workflows using representative missile system use cases.
• Collaborate closely with Government engineers and subject matter experts to optimize SysML model development processes.
• Support migration of legacy Modeling, Simulation, and Analysis (MS&A) capabilities into a cloud-native Digital Engineering environment.
• Define and maintain system requirements including performance characteristics such as Circular Error Probable (CEP).
• Develop structural models including mass properties, center of gravity, and moments of inertia.
• Model parametric characteristics including propulsion performance, thrust, specific impulse, and related system attributes.
• Support Digital Engineering transformation initiatives that improve engineering efficiency, model reuse, and analytical consistency.
• Participate in technical reviews, design discussions, and engineering trade studies supporting advanced missile system development.

Requirements

• Bachelor's degree in Engineering, Science, Mathematics, or a related technical discipline.
• Minimum 3 years of experience in Systems Engineering or a related engineering discipline.
• Demonstrated experience applying Model-Based Systems Engineering (MBSE) to aerospace, mechanical, defense, or comparable engineering systems.
• Experience developing models using Systems Modeling Language (SysML).
• Experience with one or more MBSE tools including: Cameo Systems Modeler MagicDraw Enterprise Architect Formal MBSE training or certification (INCOSE, OMG, or equivalent).
• Ability to collaborate effectively with multidisciplinary engineering teams to define modeling requirements.
• Strong communication skills and demonstrated ability to support Government adoption of MBSE methodologies.

Qualifications

• 8 or more years of Systems Engineering experience supporting Department of Defense programs.
• 3 or more years developing SysML models for aerospace or missile system applications.
• Experience supporting: Missile Performance Analysis Rocket propulsion systems Solid rocket motors Guidance, Navigation, and Control (GNC) Sensor systems including phased-array radar
• Experience creating reusable SysML model libraries.
• Experience migrating legacy engineering tools into Digital Engineering environments.
• Experience supporting cloud-native Digital Engineering ecosystems.
• Experience supporting advanced weapons system modeling, simulation, and analysis (MS&A).
• Familiarity with Digital Engineering implementation across the DoD acquisition lifecycle.
