Job summary

QuantWare is seeking a Senior Quantum Measurement and Calibration Engineer to drive experimental characterization and performance optimization of its next-generation quantum processors. You will build advanced diagnostic routines to isolate loss mechanisms, quantify crosstalk, budget gate errors, and improve fidelities across QPUs and prototypes.

You will work in the Quantum Processor team, collaborating with QPU Design, Measurement and Software Engineers.

Qualifications

• 5+ years of hands-on experience in cryogenic measurement of multi-qubit superconducting quantum processors.
• Diagnosing performance-limiting mechanisms in superconducting quantum processors.
• Deep understanding of cQED and superconducting quantum device behaviour and signal integrity challenges.
• Proficiency in Python and data analysis for quantum experiments.
• A proactive, detail-oriented mindset with a strong drive to scale quantum technology.
• You thrive in a collaborative environment and are comfortable taking ownership from day one.

Responsibilities

• Advanced measurement protocols: Create and refine advanced protocols to improve quantum gate and readout fidelities and develop diagnostics tooling to identify performance bottlenecks.
• Design and execute experiments to validate, compare, and benchmark new design elements and layout optimisations.
• Data-Driven Feedback: Analyze measurement datasets, report findings with clarity, and lead discussions with the broader engineering teams to translate experimental learnings into device design upgrades.
• Ownership: Take complete ownership of measurement campaigns – from the initial hypothesis and experiment design through cooldown, data acquisition, analysis, and final reporting.
