Job Title: Specialist, Control Systems Analysis Engineer (Systems Engineer)
Job Code: 38007
Job Location: Huntsville, AL
Job Schedule: 9/80:
Employees work 9 out of every 14 days – totaling 80 hours worked – and have every other Friday off
The Models, Simulations, and Controls department is seeking an engineer for a full-time position to support advanced missile propulsion development programs. This position focuses on the requirements, modeling, analysis, simulation, and control development of controllable solid rocket motor and throttling propulsion systems for current and future aerospace and defense applications. The role is ideal for engineers with experience in control systems, guidance/navigation/control (GNC), flight dynamics, actuation systems, dynamic modeling, and/or propulsion system analysis.
We are seeking candidates with a strong foundation in either aerospace control theory/GNC or propulsion system analysis. Because this is a specialized application area, the selected candidate will receive domain-specific training and will work closely with a multidisciplinary team of propulsion, avionics, software, and test engineers. You will work on a highly specialized and technically challenging class of aerospace control problems involving controllable solid propulsion systems.
This role offers the opportunity to apply core controls and GNC skills in a unique, high-impact area while partnering with a collaborative team across propulsion, avionics, software, and systems engineering.
- Perform control algorithm design, analysis, and evaluation for solid rocket motor throttling and related actuation systems.
- Support modeling and analysis of propulsion system dynamics, including steady-state and transient performance.
- Develop and apply dynamic models and simulations for aerospace control systems and controllable propulsion systems.
- Develop and use engineering tools in MATLAB/Simulink and C/C++ for simulation, analysis, and control development.
- Support development of system, subsystem, and component‑level requirements.
- Collaborate with avionics, software, systems, propulsion, and test engineering teams to support integrated system development.
- Support ground test and system test activities.
- Prepare and present technical work products for internal reviews, customer briefings, and program milestones.
- Support multiple ongoing and future development efforts in a cutting‑edge engineering environment.
- Travel: 10% Offsite testing as required.
- Ability to obtain a US Secret Security Clearance.
- Bachelor’s Degree and minimum 4 years of prior technical experience in controls, GNC, propulsion analysis, simulation, or related aerospace systems work experience. Graduate Degree and a minimum of 6 years of prior technical experience in controls, GNC, propulsion analysis, simulation, or related aerospace systems work experience. In lieu of a degree, a minimum of 8 years of prior technical experience in controls, GNC, propulsion analysis, simulation, or related aerospace systems work experience.
Additional Skills
- Experience in one or more of the following areas: control systems analysis or control theory
- guidance, navigation, and control (GNC)
- dynamic system modeling and simulation
- actuator/system response modeling
- vehicle dynamics, flight dynamics, or propulsion system analysis
- Experience working in a classified environment.
- Experience with MATLAB/Simulink…
