Navigation functions include the statistical processing of measured data points and their substitution into algorithms simulating physical reality. Guidance functions include the formulation of specific equations and control laws to achieve a desired position in space. Control design and analyses processes consist of the development of the control requirements for aircraft, launch vehicles and/or spacecraft.\nAbout the Role:\nWe are seeking an experienced Guidance, Navigation, and Control (GNC) Engineer for the Space Based Interceptor (SBI) program. The role will perform technical execution scope associated with missile flight vehicle control system design, guidance and algorithm development, software integration, sensor/actuator system modeling, performance analysis, hardware integrated testing, and flight testing.\nBasic Qualifications\nB.S. or M.S. in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, or related field.\nStrong foundation in missile or satellite flight dynamics, stability, and control theory (e.g., classical, state space, optimal, robust, adaptive).\nProficient in MATLAB/Simulink for modeling, linearization, and/or Monte Carlo analysis.\nFamiliarity with high fidelity 6-DoF simulations and experience designing and/or maintaining control system models.\nKnowledge of software methods or standards including safety critical items and/or version control systems (e.g., Git, Gitlab).\nAbility to develop and execute unit, integration, and/or system level tests (e.g., HIL, SIL, flight test).\nStrong written and oral communication skills for cross functional teams and senior leadership.\nDesired Skills\nExperience with Missile or Satellite Attitude Control System (ACS) or Thrust Vector Control (TVC) hardware/software, regardless of actuation type (e.g., hydraulic, electromechanical, flexible nozzle, RCS, etc.).\nExperience with stability & control analysis and guidance law development.\nExperience modeling GNC interaction with solid propellant systems, including transients, and thrust misalignment.\nExperience in development and integration of a 6-DoF high-fidelity vehicle simulation that includes thrust vector control and bending structural dynamics.\nDemonstrated experience with test and tactical flight algorithm performance evaluation in the frequency and time domains.\nProven ability to implement and optimize control algorithms within embedded software or firmware applications for ACS or TVC. \nExperience translating control algorithms from MATLAB/Simulink into flight-ready embedded C/C++ software, including auto-code generation.\nFamiliar with agile development methodologies and processes.\nFamiliar with Hardware-in-the-Loop (HIL) test environments with models that accurately emulate actuator dynamics and sensor noise.\nExperience in planning and execution of hardware tests or flight tests, telemetry handling, and post-test analysis, or reconstruction.\nPay Information\nFull-Time Salary Range: $122600.00 - $227600.00\nAt Lockheed Martin, we know mission success starts with taking care of our people. Our Total Rewards program is designed to attract top talent, support your well-being, and help you grow-both professionally and personally.\nThe salary range for this position is as listed on the requisition.
