About The Position

At RTX, the world largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world’s most complex problems. With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can. Together, we push the boundaries of known science and find new ways to connect and protect our world. Raytheon brings the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. We deliver solutions that help our nation and allies defend freedom and deter aggression, creating a safer, more secure world. Join us and help shape the future of aerospace and defense. Raytheon is seeking a Senior Systems Engineer- Guidance, Navigation, and Control Analyst (GNC) : Location: Pasadena, California. This role is critical for the risk reduction and requirement-definition phase of the project's mechanisms. High-fidelity modeling of electromechanical actuators and sensors is required to validate designs against testbed data and to inform the specifications of future hardware iterations. Distill complex models into low-fidelity versions for integration into larger system-level simulations. Provide rapid-turnaround study results for sponsors and maintaining long-term, high-fidelity simulation infrastructure.

Requirements

Bachelor’s in Science, Technology, Engineering, or Mathematics (STEM preferred)
Minimum of 5 years of prior engineering experience.
Experience in Matlab, Simulink and the C programming language.
Experience developing clear and adaptable models of complex electromechanical systems.
Experience delivering professional presentations.
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.

Nice To Haves

Experience in signal Processing.
Experience with high-bandwidth mechatronics and dynamics.

Work in a complex multi-task, schedule-driven environment.
Perform effectively with minimal day-to-day oversight
Advanced degree

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.
