Job description

Quantum Measurement Engineer – QPU Diagnostics & Calibration at QuantWare, Delft. A mid-level full time position in the Product Development team, listed under hardware engineering.

At QuantWare, you’ll be part of a high-performing team of world-class experts in an ambitious, fast-moving environment. From day one, you’ll have the trust, tools, and support to do your best work. Here’s what you can expect: Competitive salary - A salary that reflects the impact and importance of the role (and of course 8% holiday allowance) Pension that’s built to last - A generous and future‑proof pension plan that includes partner and dependent coverage.

Flexibility built on trust - We focus on outcomes. Work flexibly, in a hybrid setup, with an open vacation policy that lets you manage your time Personal growth - We invest in your L&D, with a budget available to each team member, dependent on their individual ambitions, development needs, and performance A connected team - We make space to celebrate wins together, with team events, offsites, and spontaneous moments that bring us closer

Responsibilities

• Advanced measurement protocols: Create and refine advanced protocols to improve quantum gate and readout fidelities and develop diagnostics tooling to identify performance bottlenecks (e.g. noise and TLS spectroscopy, gate error budgeting).
• Design and execution of experiments: Design and execute experiments to validate, compare, and benchmark new design elements and layout optimisations (e.g. coupling schemes, filtering, crosstalk mitigations).
• 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.

Requirements

• 5+ years of hands‑on experience in cryogenic measurement of multi‑qubit superconducting quantum processors.
• Extensive experience in 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.
