Position Title: Senior Model-Based Systems Engineer (MBSE Missile Systems)
Location: Beavercreek, OH
Company: Cornerstone Signals & Cyber Technologies LLC

Position Overview


Cornerstone seeks a Senior Model-Based Systems Engineer (MBSE) to support a Digital Engineering (DE) transformation effort focused on missile performance modeling, simulation, and analysis (MS&A). This role supports government customers in migrating legacy tools, algorithms, and processes into a cloud-native digital engineering pipeline using a phased implementation approach.

The position focuses on developing and refining end-to-end missile system models using SysML, enabling improved analytical rigor, scalability, and decision support for advanced weapons systems.

Key Responsibilities


Scope and define requirements for representing missile systems within SysML-based MBSE environments using existing engineering data and analysis

Develop and maintain end-to-end missile system models, including:

Requirements (e.g., Circular Error Probable CEP)

Structural attributes (e.g., mass properties, moments of inertia)

Parametric characteristics (e.g., propulsion performance, specific impulse)

Create a scalable and repeatable workflow for generating new missile models within a digital engineering ecosystem

Apply, test, and refine MBSE workflows using real-world missile system use cases


Collaborate with government stakeholders and subject matter experts to optimize modeling approaches and workflows


Support the transition of legacy MS&A capabilities into a modernized, cloud-enabled digital engineering framework


Contribute to advancing MBSE adoption across missile performance analysis efforts


Basic Qualifications


Minimum 8 years of experience in systems engineering or a related technical field

Demonstrated experience applying Model-Based Systems Engineering (MBSE) to:

• Aerospace systems
• Mechanical systems
• or related engineering domains

Proven experience developing models using:

• SysML
• MBSE tools such as Cameo Systems Modeler, MagicDraw, or Enterprise Architect

Formal MBSE training or certification (e.g., INCOSE, OMG, or equivalent)

Ability to collaborate across multidisciplinary engineering teams to define and implement modeling requirements


Strong work ethic with demonstrated ability to support customer adoption of MBSE methodologies


Desired Qualifications


5+ years of experience applying SysML specifically within aerospace or missile system applications, including:

• Rocket propulsion systems
• Sensor systems (e.g., phased array radar)

Experience supporting missile performance analysis or weapons system modeling environments


Familiarity with Digital Engineering (DE) ecosystems and cloud-based modeling environments

Education Requirements


Bachelors degree in:

• Engineering
• Science
• Mathematics
• or a related technical discipline

Security Clearance

• Active Top Secret clearance with SCI eligibility is required
• U.S. Citizenship is required
