Modeling & Simulation Systems Engineer III

The role

The Systems Engineer III – MSAD contributes to the design, development, and analysis of modeling, simulation, and control systems for propulsion and aerospace systems. The role involves algorithm development, system-level performance assessments, and multidisciplinary collaboration.

What you will do

• 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, and trade studies.
• Apply physics-based modeling to mechanical, thermal, and aerodynamic subsystems.
• Support modeling and simulation planning for new programs and R&D initiatives.
• Collaborate with multidisciplinary GNC, software, systems, and test teams.
• Author technical documentation and mentor less experienced engineers.

Required qualifications

• Bachelor’s or master’s degree in systems engineering, aerospace engineering, mechanical engineering, electrical engineering, or a related STEM field.
• 4–7 years of experience in modeling, simulation, control systems, or estimation algorithm development in the aerospace or defense industries.
• Strong background in dynamic system modeling, control system design, and simulation infrastructure.
• Proficiency in MATLAB/Simulink, Python, or equivalent modeling and control toolchains.
• Understanding of classical control techniques.
• Competency in verification and validation of models and their use within system architectures.
• Ability to apply physics-based modeling and multi-domain simulation development.
• Ability to generate SysML diagrams covering product structure, behavior, technical logic, engineering processes, and test execution.
• U.S. citizenship is required.
• Must have or be able to obtain and maintain an active DoD Secret Clearance.
• Must be a U.S. Person (US Citizen, lawful permanent resident, or protected individual).
• Must be eligible to obtain any required export authorizations from the U.S. Department of State or the U.S. Department of Commerce.

Nice to have

• Experience in propulsion modeling, including solid rocket motors and controllable solids.
• Prior experience supporting Department of Defense (DoD), Missile Defense Agency (MDA), or equivalent government programs.

Benefits

• Flexible Time Off (FTO)
• Comprehensive medical, dental, and vision coverage
• Flexible, affordable gym memberships
• 401(k) retirement plan with a 50% company match on contributions up to 8%
• Company wellness programs
• Additional voluntary benefits and employee support resources

Before you apply

• U.S. citizenship is required due to government program requirements.
• Must have or be able to obtain and maintain an active DoD Secret Clearance.
• Must be a U.S. Person to conform to U.S. Government export regulations.
