Senior Quantum Algorithms Engineer
QuantWare
Designs, fabricates scalable superconducting QPUs
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 Senior Quantum Algorithms Engineer, you accelerate the discovery of practical applications for large VIO-powered QPUs. You identify which fault-tolerant algorithms can deliver real-world advantage, define what a problem must look like for that advantage to hold, and work with partners’ domain experts to find use cases that fit. Where advantage is expected but not yet proven, you lay out how to test it on real near-future systems. Your findings feed directly into our processor and VIO requirements, and into how we present QuantWare’s applications work to the outside world.
Algorithms for advantage: Identify the most promising algorithms for practical advantage, and the problem requirements for it to hold (like data structure, classical hardness and verifiability).
Use cases: Work with partners and their domain experts to identify practical use cases that meet those requirements.
Advantage roadmaps: Develop roadmaps to test expected-but-unproven advantage against classical baselines on real near-future quantum systems.
Hardware requirements: Translate findings into processor and VIO requirements, targets and priorities, together with our hardware and system engineering teams.
Architecture comparisons: Compare QPU architectures on compute efficiency, through resource estimates and benchmarks on real systems.
External voice: Publish, and represent QuantWare’s applications work at conferences and with partners.
Quantum algorithm PhD, with broad research experience across multiple fault-tolerant quantum algorithm families.
Track record of mapping algorithms to real-world problems together with domain experts.
A clear, critical view on what real-world quantum advantage requires.
Strong communicator who can bridge technical and non-technical audiences.
Typically 5+ years of post-PhD research or industry experience.
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.
QuantWare designs, fabricates, and sells superconducting quantum processors (QPUs) to a global customer base, serving as a specialized hardware supplier for the quantum ecosystem. Its QPUs use the VIO 3D integration architecture to route control signals vertically, enabling dense, modular processors like Soprano and Contralto and paving the way for large-scale chips such as the VIO-40K (up to 10,000 qubits). The company differentiates itself by focusing exclusively on QPUs and building high-volume fabrication capacity through initiatives like KiloFab, rather than delivering complete quantum systems. Its goal is to accelerate the advent of useful quantum computing by providing scalable, factory-ready quantum hardware to startups, research institutes, and tech giants.
