Quantum R&D Engineer – Traveling Wave Parametric Amplifier (TWPA)

About the role

As a Quantum R&D Engineer – TWPA you will be the domain expert on the physics and architecture of Josephson Travelling Wave Parametric Amplifiers. You will translate product specifications into TWPA layouts and circuit designs, pushing the limits of microwave engineering and cryogenic performance. The role combines advanced simulation, fabrication, and integration of on‑chip components in a fast‑moving research environment.

Key responsibilities

• Translate product specifications and features into TWPA layouts and circuit designs through detailed simulations.
• Drive miniaturisation of TWPA architectures and integrate critical peripheral components on‑chip.
• Research and develop extensions of bandwidth, improve noise performance, and implement functions such as pump coupling and isolation.
• Present findings and technical proposals clearly to both technical and non‑technical stakeholders, influencing roadmap and product decisions.
• Stay up‑to‑date with state‑of‑the‑art parametric amplification literature and contribute new ideas to the team.

Required profile

• PhD or equivalent industry experience in quantum‑limited amplification, parametric amplifiers, or related superconducting microwave circuits.
• Deep expertise in non‑linear metamaterials, Josephson circuits, and mixing processes.
• More than three years of hands‑on experience with advanced microwave design and simulation, with a proven track record of matching simulations to cryogenic measurements.
• Strong independent, creative problem‑solving ability in an R&D setting.
• Excellent communication skills to present technical findings and influence cross‑disciplinary decisions.

Required skills

• CST
• HFSS

What we offer

• Competitive salary with 8 % holiday allowance.
• Generous pension plan covering partners and dependents.
• Hybrid work flexibility with an open vacation policy.
• Personal development budget for learning and growth.
• Team events, off‑sites, and a collaborative culture.
• Commitment to diversity and inclusion throughout the recruitment process.
