Quantum R&D Engineer – Processor Development

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 Senior Quantum R&D Engineer to join our Quantum Processor team and develop the next generation of Quantum Processing Units (QPU). This role is focused on improving processor performance by designing, validating and iterating on-chip architectures like inter-qubit couplers and readout architectures. You will take ownership of the end-to-end development cycle, creating designs, collaborating with our fabrication teams and performing cryogenic measurement to inform design iterations. You will directly contribute these improvements into our large-scale QPUs.

What you’ll be doing

• Design & Simulate: Conceive, model, and layout next-generation, large-scale superconducting quantum processor architectures. Design custom test vehicles and prototypes to compare and validate new component implementations (like inter-qubit couplers and readout architectures), before integrating them into full-scale processors.

• Measure & Validate: Close the feedback loop by designing and performing cryogenic measurements on your own designs to validate performance and inform design improvements.

• Ownership: Take complete ownership of device or component development – from the initial concept through design, simulation, experiment, data analysis, and iteration.

• Automate: Write and improve code to automate design, simulation, and measurement workflows.

• Collaborate: Collaborate closely with design and measurement engineers, teams to ensure rapid design-to-test cycles

Your Profile

• 5+ years of hands-on experience in multi-qubit superconducting quantum device development

• Deep understanding of cQED, quantum microwave circuits and superconducting qubits.

• Extensive experience in design and cryogenic measurement of superconducting qubit circuits

• Proficiency in Python and software tools for quantum design and experiments (e.g. HFSS, Comsol, pyEPR, scqubits, Quantum Metal, KLayout, etc.)

• 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! Research shows women often self-select out if they don't meet every requirement. Here's our take: nobody ticks every box. This is a description of our ideal candidate, not a filter. If most resonates and you're keen to learn the gaps, apply. We hire for trajectory, not perfection.

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 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.
