Job summary

QuantWare is seeking a Quantum R&D Engineer - TWPA to act as a domain expert on the physics and architecture of Travelling Wave Parametric Amplifiers, translating product specifications into TWPA layouts and on‑chip designs through simulations.

You will drive miniaturisation, integrate peripheral components, and explore bandwidth and noise improvements while presenting findings to stakeholders to influence roadmap and product decisions.

Qualifications

• PhD or equivalent industry experience in quantum-limited amplification or closely related superconducting microwave circuits.
• Deep expertise in non-linear metamaterials, Josephson circuits, and mixing processes.
• >3 years of hands-on experience with advanced microwave design and simulation (e.g., CST, HFSS) with a proven track record of matching simulations to cryogenic measurement data.
• Track record of independent, creative problem-solving in a research and development setting.
• Excellent communication skills, with the ability to clearly present technical findings and influence decisions across disciplines.
• Passionate about qubit readout amplification; pushing amplifier performance to the physical limits and thrive in a fast R&D environment.

Responsibilities

• Translate product specifications into TWPA layouts and circuit designs through simulations.
• Drive the miniaturisation of TWPA architectures and integrate critical peripheral components on-chip.
• Research directions include extending bandwidth, improving noise performance, and integration of peripheral functions like pump coupling and isolation.
• Present findings and technical proposals clearly to both technical and non-technical stakeholders, influencing roadmap and product decisions.
• Stay informed of relevant literature and state-of-the-art techniques in parametric amplification, actively contributing new ideas and approaches to the team.
