If you want to put your skills to work where the stakes
The Systems Engineer III – MSAD is responsible for contributing to the design, development, and analysis of modeling, simulation, and control systems supporting propulsion and aerospace systems. The role supports program execution through modeling, algorithm development, system-level performance assessments, and multidisciplinary collaboration, with increasing technical independence and ownership under the guidance of senior engineers.
The position reports to the Engineering Department Manager and is part of the Strategic Systems department based in Folsom, CA. This role is hybrid and is located in Folsom, CA.
In this role, the essential functions are:
Develop models and control algorithms for propulsion, flight control, and guidance subsystems.
Support development of system simulation architectures for design iteration, verification, and validation.
Perform dynamic system studies and data analysis to assess system behavior, validate models against test data, and improve simulation fidelity and reliability.
Support control system topology definition, gain-tuning methodologies, and model anchoring techniques.
Contribute to program performance engineering through requirement derivation, margin analysis, performance trade studies, and Monte Carlo, sensitivity, and parametric analyses.
Apply physics-based modeling to mechanical, thermal, and aerodynamic subsystems and support modeling and simulation planning for new programs and R&D initiatives.
Collaborate with multidisciplinary GNC, software, systems, and test teams and participate in technical reviews and milestone events.
Author technical documentation, support technical trade studies and concept maturation, and mentor less experienced engineers as needed.
