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

Bachelor’s 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
