Experimental Quantum Engineer - R&D

About the role

As an Experimental Quantum Engineer - R&D at QuantWare, you will sit at the center of our experimental hardware efforts, operating and elevating our state‑of‑the‑art cryogenic measurement infrastructure. You will characterise novel R&D prototypes, analyse performance data, and drive cross‑functional root‑cause analysis alongside Design, Fabrication, and Measurement disciplines.

Key responsibilities

• Cryogenic Infrastructure Management: drive day‑to‑day operation, maintenance and strategic upgrades of cryostats and measurement setups.
• Measurement & Code Development: build, refine and automate Python‑based routines for high‑throughput device characterisation and hardware control.
• Prototype Characterisation & Analysis: perform precision measurements on novel prototypes, analyse data, formulate hypotheses and collaborate with cross‑disciplinary teams.
• Reliability & Scaling: design and execute cryogenic reliability studies and optimise setups for increasing throughput demands.
• Reporting & Process Standardisation: streamline experiment documentation, data pipelines and technical reporting for seamless knowledge sharing.

Required profile

• Education: MSc in Physics, Applied Physics, Electrical Engineering or related field (PhD a plus).
• Cryogenic Expertise: hands‑on experience with dilution refrigerators, pulse‑tube or 4 K cryostats and wet helium/nitrogen systems.
• RF & Superconducting Hardware: strong background in microwave/RF measurement techniques for superconducting qubits and solid‑state systems.
• Software Skills: proficiency in Python for data analysis, instrumentation control and test automation, and experience using Git.
