Systems Engineer IV - MSAD

Voyager Technologies•Folsom, CA

About The Position

The Level IV Modeling, Simulation, and Controls Engineer contributes to the design, development, and analysis of control systems and simulation architectures supporting propulsion and aerospace systems. The role supports program execution through high-fidelity modeling, algorithm development, and performance assessment, applying expertise in solid rocket motors and controllable solids. It calls for increasing independence and technical ownership while working with engineering disciplines, project teams, and customers. The engineer develops propulsion and flight-control models and algorithms, supports simulation architecture and verification and validation, conducts controllability and performance studies, and contributes to requirements, trade studies, propulsion modeling, and mission concept development. The position also involves model integration, technical documentation, customer engagement, technical reviews, and mentoring junior engineers. Travel may be up to 10%, and work may take place in secure or classified environments. Applicants must meet U.S. Government export-control eligibility requirements and have or be able to obtain and maintain an active DoD Secret Clearance.
