RF/Microwave Researcher

IBM Quantum is seeking talented researchers to contribute to the development of advanced high-performance circuits and subsystems for quantum computing systems. We focus on the design and system integration of microwave components such as quantum limited and low-noise amplifiers and isolators in superconducting qubit readout chains. The successful candidate will contribute to the development of novel superconducting qubit measurement systems. We are looking for a team player with strong writing and presentation skills, who is able to create and communicate technical ideas, and collaborate with a multi-disciplinary team. The candidate must be able to work successfully with a diverse and dynamic team of both operational and technical personnel, collaborate with team members, work independently, and take their own initiative. Demonstrated RF/microwave filter design knowledge: notch filters, bandpass filters, diplexers Mastery of EM modeling, circuit design and layout tools e.g. Keysight ADS, EMPro tools, Ansys HFSS, Cadence/Clarity tools, COMSOL
