Quantum RF Design Engineer: Superconducting Amplifiers

Entangled Future; Reading; On-site; GBP 70,000 - 90,000; Full time

Job summary

Oxford Quantum Circuits in Reading, England, invites a mid-level Quantum Engineer to join the Device Scaling team. You\'ll own development, modelling and optimisation of superconducting amplifier technologies and their integration into our quantum processor readout systems, spanning circuit simulation through cryogenic testing.

This hands-on role emphasizes evidence-based engineering, cross-disciplinary collaboration, and building reusable tools to accelerate future quantum hardware development.

Qualifications

• Strong practical experience in RF and microwave circuit design, analysis and experimental characterisation.
• Experience with superconducting amplifier technologies or related low-noise microwave systems.
• Proven experience with circuit and EM simulations, understanding modelling assumptions and limitations.
• Experience designing or characterising electronic or microwave devices with fabrication, packaging and integration constraints.
• Strong scientific programming skills, preferably Python.
• Experience developing or improving scientific simulation, measurement or optimisation workflows.
• Hands-on experience using RF and microwave instrumentation to validate designs and resolve issues.
• Knowledge of microwave networks, impedance matching and device layout for fabrication.
• Track record delivering complex technical projects with sound engineering judgement.
• Strong communication and collaboration across disciplines.

Responsibilities

• Design, simulate and optimise superconducting amplifier circuits and microwave environments.
• Develop and characterise amplifier devices, investigating gain, bandwidth, noise, saturation and stability.
• Design RF and microwave networks for impedance matching, coupling, filtering, pumping and signal routing.
• Develop physical device layouts and collaborate with fabrication and packaging teams to optimise manufacturability and performance.
