Job summary

RTX is seeking an experienced engineer to support risk reduction and requirements-definition for electromechanical mechanisms. You will develop high-fidelity simulations, validate them against test data, and create surrogate models for system-wide analyses.

Ideal candidates have 8+ years in STEM fields, hands-on experience with Matlab/Simulink and C, and proven ability to present findings clearly to sponsors and stakeholders. Security clearance and US citizenship are required.

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.

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 for 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.
• Participate in vendor meetings and technical reviews to absorb critical design information.
• Act as a flexible resource within a small team, providing overlap and support for other GNC functions.
• Translate complex simulation data into clear, concise plots and PowerPoint presentations.

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.

What You Will Do

This role is critical for the risk reduction and requirement-definition phase of the project's mechanisms.

• 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 to ensure physical accuracy.
• Risk Reduction & Requirements: Utilize high-fidelity models to conduct risk reduction activities and establish technical requirements for future versions of mechanisms.
• System Integration: Create and maintain low-fidelity "surrogate" models that approximate actuator behavior for use in larger, integrated 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 that behavioral models accurately reflect external hardware and software specifications.
• Technical Versatility: Act as a flexible resource within a small team, providing overlap and support for other GNC functions as bandwidth requires.
• Communication: 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.
• Work in a complex multi-task, schedule-driven environment.
• Perform effectively with minimal day-to-day oversight.
• Advanced degree.
