Quantum Engineer - Hybrid Circuit-QED Measurement

As a Quantum Engineer at EeroQ, you will use your skills and experience in experimental quantum physics and ultra-low-temperature measurement to develop circuit QED-based devices and measurement protocols for the control and manipulation of single-electron spin qubits on the surface of liquid helium. As well as developing and maintaining state-of-the‑art quantum measurement schemes, instrumentation solutions and laboratory infrastructure, Quantum Engineers will contribute to the design of new devices and nanofabrication process flows.

You will collaborate with a team of engineers and scientists, using the results of your measurements and data analysis to guide the development of a new and exciting platform for quantum computing.
