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.\nWe 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.\nYou 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.\nEssential Functions:\nPerform control algorithm design, analysis, and evaluation for solid rocket motor throttling and related actuation systems.\nSupport modeling and analysis of propulsion system dynamics, including steady-state and transient performance.\nDevelop and apply dynamic models and simulations for aerospace control systems and controllable propulsion systems.\nDevelop and use engineering tools in MATLAB/Simulink and C/C++ for simulation, analysis, and control development.\nSupport development of system, subsystem, and component-level requirements.\nCollaborate with avionics, software, systems, propulsion, and test engineering teams to support integrated system development.\nSupport ground test and system test activities. \nPrepare and present technical work products for internal reviews, customer briefings, and program milestones.\nSupport multiple ongoing and future development efforts in a cutting-edge engineering environment.\nTravel: 10% Offsite testing as required.\nAbility to obtain a US secret security clearance.\nQualifications:\nBachelor’s Degree and minimum 4 years of prior technical experience in controls, GNC, propulsion analysis, simulation, or related aerospace systems workexperience. Graduate Degree and a minimum of 6 years of prior technical experience in controls, GNC, propulsion analysis, simulation, or related aerospace systems workexperience. In lieu of a degree, a minimum of 8 years of prior technical experience in controls, GNC, propulsion analysis, simulation, or related aerospace systems workexperience.\nPreferred Additional Skills:\nBachelor’s degree in Aerospace, Electrical, Mechanical, Systems Engineering or related technical discipline is preferred.\nActive US Secret security clearance is preferred.\nExperience in one or more of the following areas:control systems analysis or control theory\nguidance, navigation, and control (GNC)\ndynamic system modeling and simulation\nactuator/system response modeling\nvehicle dynamics, flight dynamics, or propulsion system analysis\n\nExperience working in a classified environment.\nExperience with MATLAB/Simulink and at least one programming language such as C, C++, or Python.\nExperience with aerospace controls, GN&C, missile/munition control systems, flight simulation, or vehicle performance analysis.\n\nExperience with propulsion systems, especially propulsion controls, throttling systems, integrated propulsion/vehicle modeling, or propulsion test support.\n\nExperience with high-fidelity simulation, time-domain analysis, and control system performance assessment.\n\nFamiliarity with 6-DoF or reduced-order dynamic simulations, actuator models, or hardware/software integration.\n\nExperience supporting test planning, test execution, hardware-in-the-loop/software-in-the-loop activities, or post-test data analysis.\n\nExperience developing or evaluating embedded or real-time control-related software.\n\nTest and evaluation of dynamic aerospace
