Job Description
Our Client is seeking a Guidance Navigation Control Engineer III for an opportunity with our client in the Aerospace and Defense Manufacturing industry.
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 direction on seeker and tracking approaches, and collaborate with cross‐functional teams to ensure system reliability and mission success.

Responsibilities:

• 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.

Required Qualifications:

• 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, missile, 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.

Preferred Qualifications:

• 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 and measurement models and integrating them into end‐to‐end 6‐DOF simulations.
• Experience with seeker measurements such as angle‐only measurements, line‐of‐sight (LOS) rate estimation, pixel/centroid‐based measurements for infrared seekers, and/or range, range‐rate (Doppler), azimuth/elevation, and angle‐only tracking for RF seekers.
• Experience with data association methods, track initiation and maintenance logic, and multi‐target tracking in the presence of false alarms and clutter.
• Proven ability to lead small technical teams or work packages, mentor junior engineers, and communicate complex technical concepts to diverse stakeholders.
• Strong proficiency in C/C++ and Python and experience with software development tools such as Jira, version control, and continuous integration workflows in a Linux environment.
