Quantum Hardware Engineer – Superconducting Hardware (SPC)
About the Role
Quantum Hardware Engineer specialising in superconducting hardware (SPC) to help develop, characterise, and optimise next-generation superconducting quantum devices and cryogenic systems.
You will work at the intersection of superconducting circuit design, microwave engineering, nanofabrication, and low-temperature measurement, contributing directly to the performance and stability of a cutting-edge quantum hardware platform.
Responsibilities
- Design, build, and characterise superconducting quantum devices, including resonators, qubits & parametric quantum amplifiers.
- Set up and operate cryogenic measurement platforms (dilution refrigerators, ADRs), enabling high-fidelity microwave characterisation at mK temperatures.
- Optimise device performance through loss analysis, materials improvements, packaging refinement, and electromagnetic modelling.
- Develop and maintain microwave signal chains, biasing networks, and low-noise readout paths suitable for quantum-sensitive hardware.
- Perform time-domain and frequency-domain measurements to evaluate coherence, noise contributions, and device-level stability.
- Collaborate with nanofabrication teams to iterate device designs and implement new process flows.
- Create automated measurement routines, data pipelines, and documentation for reproducible device characterisation.
- Work cross-functionally with quantum control, theory, and systems teams to inform architecture and scaling decisions.
Requirements
- Hands-on experience with superconducting quantum devices such as resonators, qubits, SQUIDs, Parametric Quantum Amplifiers or other cryogenic microwave components.
- Practical proficiency operating dilution refrigerators or cryostats, including wiring, calibration, and low-noise measurement.
- Strong grounding in microwave engineering, S-parameters, cryogenic RF components, and impedance-matched signal chains.
- Familiarity with nanofabrication (thin films, etching, liftoff, deposition) for superconducting or semiconductor quantum devices.
- Experience conducting low-temperature coherence, loss, noise, or material-dependent performance studies.
- Competence in automation and data analysis (Python, LabVIEW, MATLAB, or equivalent).
- Clear communication skills and ability to work across multidisciplinary hardware teams.
- Educational background in physics, electrical engineering, quantum engineering, or related fields.
