Model- Systems Engineer; MBSE in Dayton

Job Description

Position Title: Senior Model-Based Systems Engineer (MBSE – Missile Systems)

Location: Beavercreek, OH

Company: Cornerstone Signals & Cyber Technologies LLC

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‑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.

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
.

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, Magic Draw, 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
.

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.

Bachelor’s degree in:

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

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