Jr. Modeling and Simulation Software Engineer

MTSI is seeking a highly motivated Modeling & Simulation SW Developer to support the Missile Defense Agency (MDA) in assessing the capabilities of the Missile Defense System (MDS). This critical role will involve working in a distributed Hardware-In-the-Loop (HWIL) simulation environment, contributing to Continuous Developmental Integration (CDI) activities, MDS Ground Test (GT) events, and MDS Flight Test support. Our team is at the forefront of software assurance and cloud modernization for Model & Simulation (M&S) systems.

• We partner closely with MDA Azure Cloud initiatives to containerize critical software while ensuring security, performance, and scalability.
• Code verification, development, & prototype development - ensuring software quality, security, and maintainability.
• Code reviews for framework and supporting M&S software.
• Baseline qualification testing - validating operating system patches, network updates, and hardware changes before enterprise deployment.
• Cloud and containerization leadership - enabling the transition of M&S frameworks and element software into modern, containerized environments.
• Supporting advanced development through a high-side AI server cluster for code development, analysis, and documentation.
  
  

Key Responsibilities
