About the Team:

The Modeling & Simulation team builds the simulation capabilities used to design integrate test and validate advanced aerospace and defense systems. We develop physics-based models simulation environments and analysis tools that help engineering teams evaluate system behavior improve designs and reduce risk before hardware design integration test and fielding.

About the Role:

As a Modeling & Simulation Engineer for Radars you will develop integrate and validate models of radar and RF sensing systems. You will work across analytical behavioral measurement-level signal/IQ-level and closed-loop system models selecting the fidelity appropriate to the design decision software integration activity test event or verification objective. You will partner with radar architecture RF and antenna signal processing tracking embedded software systems engineering test and product teams.
