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 Quantum R&D Engineer - TWPA, you will act as a domain expert on the physics and architecture of our Josephson Travelling Wave Parametric Amplifiers and will translate product specifications into TWPA architectures. You will focus on pushing the fundamental limits of our microwave engineering, solving complex simulation-to-fabrication mismatches, and spearheading the integration of advanced on-chip components.
What you'll be doing
Translate product specifications & features into TWPA layouts and circuit designs through simulations.
Drive the miniaturisation of our TWPA architectures and successfully design and integrate critical peripheral components on-chip
Research directions include extending bandwidth, improving noise performance, and integration of peripheral functions like pump coupling and isolation.
Present findings and technical proposals clearly to both technical and non-technical stakeholders, influencing roadmap and product decisions.
Stay informed of relevant literature and state-of-the-art techniques in parametric amplification, actively contributing new ideas and approaches to the team.
Your Profile
PhD or equivalent industry experience in quantum-limited amplification, parametric amplifiers (e.g. TWPAs, JPAs), or closely related superconducting microwave circuits.
Deep expertise in non-linear metamaterials, Josephson circuits, and mixing processes.
>3 years of hands-on experience with advanced microwave design and simulation (e.g., CST, HFSS) with a proven track record of matching simulations to cryogenic measurement data.
Track record of independent, creative problem-solving in a research and development setting.
Excellent communication skills, with the ability to clearly present technical findings and influence decisions across disciplines.
Passionate about qubit readout amplification; pushing amplifier performance to the physical limits and thrive in a fast R&D environment.
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.
