Guidance, Navigation, and Control Analyst (Systems Engineer) (Onsite)

About the role

Raytheon is seeking a Guidance, Navigation, and Control Analyst (Systems Engineer) to join their team in Pasadena, California.

Responsibilities

• Maintain, modify, and develop high-fidelity behavioral simulations of electromechanical actuators and sensors.
• Tune and validate simulations against actual testbed data to ensure physical accuracy.
• Utilize high-fidelity models to conduct risk reduction activities and establish technical requirements for future versions of mechanisms.
• Create and maintain low-fidelity "surrogate" models that approximate actuator behavior for use in larger, integrated system simulations.
• Execute rapid-turnaround tasks (2–3-week cycles) to support sponsor-driven studies, delivering results via plots and presentations.
• Provide ongoing maintenance and updates to the project’s primary simulation environment to ensure stability for other project stakeholders.
• Participate in vendor meetings and technical reviews to absorb critical design information, ensuring that behavioral models accurately reflect external hardware and software specifications.
• Act as a flexible resource within a small team, providing overlap and support for other GNC functions as bandwidth requires.
• Translate complex simulation data into clear, concise plots and PowerPoint presentations for internal and external stakeholders.

Qualifications

• Typically requires a Bachelor’s in Science, Technology, Engineering, or Mathematics (STEM preferred) and a minimum of 8 years of prior engineering experience.
• Experience in Matlab, Simulink, and the C programming language.
• Experience in signal processing.
• Experience developing clear and adaptable models of complex electromechanical systems.
• Experience delivering professional presentations.
• Experience with high-bandwidth mechatronics and dynamics.
• Experience in the research and development of precision pointing systems.
• Experience working directly with external vendors and hardware suppliers.
• An active and transferable TS/SCI CI Poly U.S. government issued is required prior to start date. U.S. citizenship is required, as only U.S. citizens are eligible for the required security clearance.

What We Offer

• Medical, dental, vision, life insurance, short-term disability, long-term disability, 401(k) match, flexible spending accounts, flexible work schedules, employee assistance program, Employee Scholar Program, parental leave, paid time off, and holidays.
