Quantum R&D Engineer – Processor Development

About the role

We are seeking a Senior Quantum R&D Engineer to join our Quantum Processor team and develop the next generation of Quantum Processing Units (QPU). The role focuses on improving processor performance by designing, validating and iterating on‑chip architectures such as inter‑qubit couplers and readout systems.

Key responsibilities

• Conceive, model and layout next‑generation, large‑scale superconducting quantum processor architectures.
• Design custom test vehicles and prototypes to validate new components before full‑scale integration.
• Design and perform cryogenic measurements on your own designs to close the feedback loop.
• Take complete ownership of device or component development from concept through iteration.
• Write and improve code to automate design, simulation and measurement workflows.
• Collaborate closely with design and measurement engineers to ensure rapid design‑to‑test cycles.

Required profile

• 5+ years of hands‑on experience in multi‑qubit superconducting quantum device development.
• Deep understanding of cQED, quantum microwave circuits and superconducting qubits.
• Extensive experience in design and cryogenic measurement of superconducting qubit circuits.
• Proficiency in Python and quantum‑design software tools (e.g., HFSS, Comsol, pyEPR, scqubits, Quantum Metal, KLayout).
• Proactive, detail‑oriented mindset with a strong drive to scale quantum technology.
• Comfortable taking ownership from day one and thriving in a collaborative environment.

What we offer

• Competitive salary with an 8% holiday allowance.
• Generous pension plan covering partners and dependents.
• Hybrid work flexibility focused on outcomes, with an open vacation policy.
• Personal growth budget for learning and development.
• Team events, offsites and spontaneous moments to celebrate wins.
• Commitment to diversity and inclusion throughout the recruitment process.
