# Quantum Measurement Engineer – QPU Diagnostics & Calibration at QuantWare

- **Company:** QuantWare
- **Location:** Delft, Netherlands
- **Employment:** full-time
- **Work type:** onsite
- **Posted:** 2026-08-12
- **Last confirmed live:** 2026-09-07

## Job description

## ABOUT US

QuantWare is building the world’s most powerful quantum processors to solve humanity's greatest challenges. We do this with our unique VIO™ technology, the only QPU architecture that breaks the hardware barriers that have held quantum computing back, unlocking the path to MegaQubit quantum processors.

With VIO, we are paving the way for the hyper-scale quantum computers that will change the world. And delivering on that vision demands people who don’t shy away from tackling the hardest challenges of our time. That’s where you come in!

We are looking for a Senior Quantum Measurement and Calibration Engineer to drive the experimental characterization, diagnostic protocol development, and performance optimization of our next-generation quantum processors. You will be responsible for building advanced diagnostic routines that isolate loss mechanisms, quantify crosstalk, budget gate errors, and improve operational fidelities across our QPUs and development prototypes.

You will work in our Quantum Processor team at the core of our measurement efforts, collaborating closely with QPU Design, Measurement and Software Engineers. Your measurements will directly contribute to improving our quantum processor performance and push the edge of what is currently possible.

## What you’ll be doing

- 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.

## Your Profile

- 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.

Don't tick every box? Apply anyway. We know great candidates don't always follow a straight path, and we value diverse experience, perspectives, and ways of thinking. If this role excites you and you believe you can make an impact, we'd love to hear from you!

What We Offer:

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

Diversity & Inclusion at QuantWare

We’re an ambitious company, not only for our goals but also to become an even more diverse and inclusive team. We know this helps us with better decisions, more innovation, and strengthens our culture. In particular, we’d love to see more women in the quantum industry!

So if you’re a female talent, excited about this opportunity but don’t meet every single requirement, we still encourage you to apply.

As part of our recruitment process, candidates may be required to undergo pre-employment screening.
