Job summary

RTX in Pasadena seeks a Guidance, Navigation, and Control Analyst (Principal Systems Engineer) to lead high-fidelity modeling of electromechanical actuators and sensors, validate simulations against testbed data, and drive risk reduction and requirements for next-generation mechanisms.

The role requires 8+ years in engineering, MATLAB/Simulink and C, experience with high-bandwidth mechatronics, and active TS/SCI clearance.

Qualifications

Bachelor's in STEM and a minimum of 8 years of 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.
Active and transferable TS/SCI clearance and U.S. citizenship.

Responsibilities

High-Fidelity Modeling: Maintain, modify, and develop high-fidelity behavioral simulations of electromechanical actuators and sensors.
Model Validation: Tune and validate simulations against actual testbed data.
Risk Reduction & Requirements: Use high-fidelity models to conduct risk reduction and establish technical requirements for future versions of mechanisms.
System Integration: Create and maintain low-fidelity surrogate models for larger system simulations.
Study Support: Execute rapid-turnaround tasks (2--3-week cycles) to support sponsor-driven studies, delivering results via plots and presentations.
Simulation Maintenance: Provide ongoing maintenance and updates to the project's primary simulation environment to ensure stability for other project stakeholders.
Vendor Technical Integration: Participate in vendor meetings and technical reviews to absorb critical design information, ensuring models reflect external hardware/software specs.
Technical Versatility: Act as a flexible resource within a small team, providing overlap and support for other GNC functions.
Communication: Translate complex simulation data into clear plots and PowerPoint presentations for internal and external stakeholders.
