RF Engineer - Quantum Processor Design, Layout and Simulation

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!

Our Quantum Processor Team is seeking an RF Engineer to support the development of the next generation of processors. This role is focused on quantum chip design and the development of the design workflows that enable scalable processor development.

You will contribute to the design and optimisation of on-chip quantum components while also helping to build and maintain the underlying design infrastructure, including PDKs, DRC flows and tapeout generation tools. Working closely with experienced designers and fabrication teams, you will play an important role in supporting the development of our large-scale QPUs.

What you’ll be doing

• Contribute to the development of quantum chip design tools including PDKs, DRCs, tuners and tape-out generation tools.

• Own quantum chip design projects for R&D and product development, contributing to the design and optimisation of new quantum processors.

• Manage the full development loop for the chips you design, coordinating with fabrication and measurement teams to ensure successful transfer and execution.

• Support Foundry customers in designing chips that conform to QuantWare's PDK, providing guidance throughout the design process to meet technical and operational standards.

• Drive process improvement initiatives, identifying bottlenecks and recommending enhancements to tools, workflows, and design-to-tapeout processes for improved efficiency.

Your Profile

Core Requirements

• MSc or higher level understanding of circuit design and microwave / RF engineering.

• Hands-on experience with RF simulation tools (e.g., ANSYS HFSS, Sonnet, or equivalent), with a demonstrated ability to model and optimise microwave structures.

• 4+ years of experience in collaborative Python programming.

• A solid track record of delivering complex technical projects, demonstrating initiative, autonomy, and an eye for practical impact.

• Strong organisational and problem-solving skills. You thrive in a cross-disciplinary environment and are comfortable taking ownership from day one.

Bonus Points

• Direct experience working with superconducting and quantum circuits.

• Familiarity with quantum design and layout tools (such as Qiskit Metal, KLayout, or GDSFactory), as well as CI/CD pipelines.

• Knowledge of nanofabrication processes and cryogenic measurement techniques.

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.
