Engineer Guidance Navigation Control 2

Job#: 3054107
Job Description:
Guidance Navigation Control Engineer 3
Location: Chandler, Arizona (Onsite)
Clearance: Secret Clearance
Role Overview
This organization invites you to bring your pioneering spirit and technical leadership to collaborative teams. As a Guidance, Navigation, and Control (GNC) Engineer, you will take a lead role in missions of national importance, with a strong emphasis on seeker modeling, target tracking, and advanced GNC algorithms for missile and launch vehicle systems. This position is 100% onsite and cannot accommodate telecommute work. This role will work a 9/80 schedule, with every other Friday off.
Key Responsibilities

• 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.
• 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.
• Architect and maintain six-degree-of-freedom (6-DOF) simulations, define performance metrics, integrate hardware and software components, and conduct rigorous performance assessments and trade studies.
• 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.
• Lead the design, development, implementation, verification, and test of high-quality flight and simulation software.
• Own the design and maintenance of 6-DOF simulations used to develop, analyze, and validate flight algorithms and code.
• Optimize flight and simulation software for performance, robustness, and maintainability.
• Define and execute analysis campaigns using trajectory optimization and evaluation tools and present technical results, risks, and recommendations to program leadership.

Required Qualifications
Education: A 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. The degree must be in electrical engineering, aerospace engineering, mechanical engineering, or a related engineering discipline.
Experience: 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.
Technical Skills: Proficiency with one or more of the following: MATLAB/Simulink, Python, C/C++, or similar technical software tools, with development in a Linux environment.
Must have an active DOD secret clearance or be willing and able to maintain a DOD Secret clearance prior to starting work on the program.
Preferred Qualifications

• Active DOD Secret clearance
• An advanced degree (MS or PhD) in electrical engineering, aerospace engineering, mechanical engineering, or a related engineering discipline.
• A 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.
