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‑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.

• 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
