## 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!

As a Junior Quantum Design Engineer, you will take on a vital, hands-on responsibility in creating our next-generation quantum processors. Your core focus will be centred on the layout, simulation, and verification of quantum processor components and superconducting circuits. Collaborating directly with other design engineers alongside cross-functional R&D teams spanning fabrication, measurement, and system integration, you will transform conceptual device architectures into production-ready designs while closing the feedback loop between theoretical design intent and empirical performance. Your work will be essential as we scale to increasingly complex systems and deliver on the promise of quantum computing.

## What you'll be doing

- Design and lay out superconducting circuit components and test structures, such as resonators, qubits, and control lines.
- Perform electromagnetic and circuit simulations to predict device parameters and optimise designs.
- Contribute to design verification, including design-rule checks and review of layouts against fabrication process constraints.
- Compare simulation results with measurement data to validate design models and feed learnings back into future design iterations.
- Help develop and maintain design tooling, automated layout scripts, and documentation to make our design flow faster and more robust.

## Your Profile

- MSc in Physics, Applied Physics, Electrical Engineering, or a related field, ideally with a concentration in Quantum Computing or Quantum Technology (PhD is a plus).
- Understanding of microwave engineering, circuit theory, or superconducting devices, gained through coursework, a thesis project, or an internship.
- Experience with EM simulation tools (e.g. HFSS, Q3D, Sonnet) and layout tools (e.g. KLayout, Qiskit Metal).
- Python skills for design automation, simulation workflows, or data analysis.
- Detail-oriented mindset with a structured approach to design, verification, and documentation.
- Eagerness to learn, take ownership, and grow within a fast-moving, multidisciplinary team.
- Familiarity with superconducting qubits, circuit quantisation, or cleanroom fabrication processes is a plus.

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.
