RF Engineer (QRF)

Overview In this role you will own the RF and electromagnetics discipline for the QRF team, driving the design, testing, and calibration of broadband RF hardware for quantum sensing systems. You will work with cross-functional teams to translate laboratory concepts into repeatable, production-ready hardware and test environments. The focus is on field delivery, measurement accuracy, and reliable signal chains that connect RF design choices to atomic sensor performance. This is a hands-on role with a clear path to influence how quantum sensing hardware scales from lab to production.
