Input Technology Solutions - Huntsville, AL, United States

Input Technology Solutions is seeking a Model-Based Systems Engineer (MBSE) to support an exciting program at Redstone Arsenal in Huntsville, AL.

Overview

The candidate will analyze, model, and document system architectures and requirements for a major DoD weapons system. This role requires integrating system engineering best practices with model-based methods and tools to ensure product performance, traceability, and compliance across the lifecycle. The engineer will support decision-making through trade studies, requirement validation, and architecture modeling to drive effective system design and sustainment.

Responsibilities

• Develop, manage, and allocate weapons system requirements using both traditional and model-based methods.
• Conduct requirement analysis, trade studies, and functional decomposition within an MBSE framework.
• Build, validate, and maintain system architecture models (SysML/UML) to represent system functions, behaviors, and interfaces.
• Implement digital thread concepts, ensuring traceability from requirements through design, test, and verification.
• Manage requirement traceability using DOORS and integrate requirement sets with MBSE models in Cameo.
• Support system-of-systems integration and interface definition for missile defense programs.
• Conduct model-based simulation and analysis to evaluate system performance and identify design gaps.
• Collaborate with cross-functional teams including software, hardware, and test engineers, as well as government and contractor stakeholders.
• Prepare and deliver technical briefings and documentation to program leadership.

Required Skills

• Bachelor’s degree in a STEM field with 7+ years of experience working on missile defense or other complex DoD programs/projects.
• Experience with requirements management tools (e.g., DOORS).
• Working knowledge of Model-Based Systems Engineering (MBSE) principles, methods, and tools.
• Experience in developing and maintaining system architecture models.
• Strong analytical, problem-solving, and communication skills.
• Self-starter with the ability to work independently and as part of a team.

Preferred Skills

• Experience with GMD and C2BMC programs.
• Hands-on experience with Cameo Systems Modeler or similar MBSE tools.
• Knowledge of DoDAF/UPDM/UAF frameworks.
• Experience with SysML modeling and simulation for complex systems.
• Familiarity with verification & validation (V&V) within an MBSE environment.
• Background in digital engineering initiatives and supporting DoD digital transformation goals
