Join a culture where innovation thrives, curiosity is rewarded, and impact is real. The Level IV Modeling, Simulation, and Controls Engineer contributes to the design, development, and analysis of control systems and simulation architectures in support of propulsion and aerospace systems. This position supports program execution through high-fidelity modeling, algorithm development, and performance assessments. This role requires increasing independence and technical ownership, working closely with other engineering disciplines, project teams, and customers.

Support program performance engineering through requirement derivation, margin analysis, and performance trade studies

Conduct system-level performance assessments using Monte Carlo, sensitivity, and parametric studies

Apply physics-based modeling to develop representative simulations of mechanical, thermal, and aerodynamic systems

Contribute to ballistics modeling and propulsion system performance analysis for solid rocket motors

Develop and validate models of actuation systems for propulsion control systems and dynamic mechanisms, supporting integration into closed-loop control architectures and performance assessments.

Aid customers in developing mission CONOPS and requirements thru propulsion system modeling and controls design

Support simulation and analysis of flight vehicle control behavior for propulsion concept evaluation

Contribute to modeling and simulation planning for new programs and R&D initiatives

Collaborate with multidisciplinary teams (GNC, software, systems, test) to ensure integration of modeling products

Participate in customer engagements, technical reviews, and milestone events (SRR, PDR, CDR)

Author technical documents including model reports, simulation plans, interface definitions, and configuration records

Must have or be able to obtain and maintain an active DoD Secret Clearance

Demonstrated ability to lead engineering tasks across lifecycle phases—from requirements through verification and delivery

Solid technical foundation in modeling, control systems, and dynamic system behavior

Ability to interface with DoD customers and support team decision-making on complex technical problems

Commitment to technical rigor, quality execution, and continuous improvement

Skilled in stakeholder engagement, technical risk identification, and collaborative problem solving

Experience in propulsion modeling, including solid rocket motors and controllable solids performance

• Working knowledge of physics-based modeling for mechanical, thermal, and aerodynamic subsystems
• Bachelor’s degree in systems engineering, aerospace engineering, mechanical, electrical engineering, or related STEM field from an accredited college/university

Master’s degree in systems engineering or a related discipline is desirable and may substitute for 1 year of experience from an accredited college/university

Proficient in MATLAB/Simulink, Python, or equivalent modeling and control toolchains

Experience in propulsion system modeling and basic ballistics performance assessments

Ability to generate SysML diagrams of product structure, product behavior, technical logic, engineering process, and test execution

Ability to travel up to 10% for technical reviews, tests, or customer engagements
