Position Summary:

• In this role, you will lead the development and evaluation of guidance, navigation, and control systems for advanced aerospace applications, focusing on seeker-based missile engagements and precision intercept performance.
• You will own key algorithm design and analysis tasks, applying mathematical models, control theory, and state estimation techniques to process complex seeker measurements and drive guidance and control laws.
• Your work will include architecting and maintaining six-degree-of-freedom (6-DOF) simulations, defining performance metrics, integrating hardware and software components, and conducting rigorous performance assessments and trade studies.
• You will mentor early-career engineers, provide technical directions on seeker and tracking approaches, and collaborate with cross-functional teams to ensure system reliability and mission success.

• Leading the design, development, implementation, verification, and test of high-quality flight and simulation software; owning the design and maintenance of 6-DOF simulations used to develop, analyze, and validate flight algorithms and code; optimizing flight and simulation software for performance, robustness, and maintainability; defining and executing analysis campaigns using trajectory optimization and evaluation tools; and presenting technical results, risks, and recommendations to program leadership.
• This position is contingent upon obtaining and maintaining required program access(es), within a reasonable period of time, as determined by the company.

• Bachelor’s degree with 5 years of professional experience, or a Master’s degree with 3 years of professional experience, or a PhD with 0 years of professional experience, in electrical engineering, aerospace engineering, mechanical engineering, or a related engineering discipline.
• Must have an existing U.S. Government security clearance at the Secret level.
• Demonstrated experience with guidance, navigation, and control (GNC) concepts, algorithms, or analysis for aerospace or missile systems.
• Experience leading or significantly contributing to development, modeling, simulation, test, integration, or analysis activities for aerospace, missiles, spacecraft, or autonomous systems.
• Proficiency with one or more of the following: MATLAB/Simulink, Python, C/C++, or similar technical software tools, with development in a Linux environment.

• Advanced degree (MS or PhD) in electrical engineering, aerospace engineering, mechanical engineering, or a related engineering discipline.
• Strong foundation in control systems theory, guidance law development, and flight software implementation.
• Experience with state estimation and nonlinear filtering (e.g., Kalman Filter, Extended Kalman Filter, Unscented Kalman Filter), including tuning and performance assessment in realistic scenarios.
• Deep domain knowledge in target tracking and seeker systems (infrared and/or radio frequency), including requirements definition and algorithm design.
• Experience developing and validating target dynamics…
