Lead Systems Engineer - LO Calculations & Supplier Parts

As Lead Engineer for Low Observability Calculations, you steer high-fidelity RCS simulations to inform low-observable design choices for airframes and payloads. You’ll oversee supplier activities and ensure correlation between simulation and measurement data to deliver robust, decision-ready results. Working with cross-functional teams, you shape signature analyses and trade studies that influence system-level design. This role offers the chance to push advanced EM methods on HPC platforms while contributing to ethically-conscious defence technology. You will engage with world-leading experts and help drive meaningful impact in national security.
