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 seeking a Quantum Measurement and Calibration Engineer – Automated Calibration to join our Calibration Software team. In this role, you will sit at the intersection of Quantum Physics and Software Engineering. Your mission is to build scalable, automated QPU bring-up software. Rather than running manual measurement scripts, you will focus on developing production-grade Python software that automates device pre-screening, single- and two-qubit gate and readout calibrations, and continuous recalibration routines. You will work as a core individual contributor alongside Software Engineers, Experimental Physicists, and Production teams to make bringing up a QuantWare QPU fast, reliable, and repeatable.

What you’ll be doing

• Automated Calibration Software: Implement, improve, test, and maintain automated Python software to rapidly characterise and calibrate large-scale QPUs, including resonator spectroscopy, crosstalk matrices, single- and gates, 2-qubit gate calibration, and readout optimization.
• Code Architecture & Quality: Write, review and maintain modular Python code adhering to modern software practices (automated testing with PyTest, CI/CD, documentation, and version control).
• Ownership: Take complete ownership of software functionality – from the initial concept through coding, validation, review and integration.
• Collaborate: Collaborate closely with the internal users of the code base (including in Processor Development and Production) to gather needs, feedback and continuously improve features and calibration workflows.

Your Profile

Education & Background: PhD (or Master's degree with 2+ years of equivalent industry experience) in Physics, Quantum Information, Electrical Engineering, or Computer Science.

• Qubit Measurement: 2+ years of hands‑on experience in cryogenic measurement of multi‑qubit superconducting quantum processors, including 2‑qubit gate calibration.
• Python Programming: Strong proficiency in Python, with a proven track record of writing clean, modular, and maintainable code for data acquisition, automation, or scientific pipelines.
• Software Engineering: Working knowledge of software engineering best practices, including object-oriented design, version control (Git), code reviewing, and testing frameworks.
• Automation Mindset: Strong drive for eliminating manual measurement overhead, building robust automation scripts, and improving software quality for hardware bring‑up.
• Collaboration & Communication: Thrives in a multidisciplinary scale‑up environment, bridging experimental quantum physics cleanly with production software engineering.

What We Offer:

• 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 great candidates don't always follow a straight path, and we value diverse experience, perspectives, and ways of thinking. We know this helps us make better decisions, drives more innovation, and strengthens our culture.

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