Key Responsibilities

• Lead the design, development, implementation, verification, and test of 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.
• Apply mathematical models, control theory, and state estimation techniques to process seeker measurements and drive guidance and control laws.
• Architect and maintain simulations, define performance metrics, integrate hardware and software components, and conduct performance assessments.
• Mentor early-career engineers and provide technical direction on seeker and tracking approaches.
• Present technical results, risks, and recommendations to program leadership.

Required Qualifications

Education: A Bachelor's degree with 8 years of professional experience, a Master's degree with 6 years of professional experience, or a PhD with 4 years of professional experience 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 contributing to development, modeling, simulation, test, integration, or analysis activities for aerospace, missile, spacecraft, or autonomous systems.

Candidates must be willing and able to obtain a DOD secret clearance within a reasonable timeframe as dictated by the program prior to starting program work.

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.

Preferred Qualifications

• Active DOD secret clearance
• Advanced degree (MS or PhD) in electrical engineering, aerospace engineering, mechanical engineering, or a related discipline.
• A 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).
• Domain knowledge in target tracking and seeker systems (infrared and/or radio frequency).
• 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, and/or range, range rate (Doppler), azimuth/elevation tracking.
• Experience with data association methods, track initiation and maintenance logic, and multi-target tracking.
• Ability to lead small technical teams or work packages and mentor junior engineers.
• 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.
