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 Lead Cryogenic Engineer, you will play a key role in scaling and optimising the cryogenic infrastructure that powers our quantum hardware. From achieving near state-of-the-art coherence performance to ensuring high uptime and throughput across our cryostat fleet, your work will directly influence the success of our R&D and product development efforts. You’ll lead the commissioning and continuous optimisation of cryogenic systems and infrastructure, enabling the next generation of quantum processors.
Core Responsibilities
Define, build, ramp-up, and operate a large-scale cryogenic test facility, including dilution refrigerators and supporting infrastructure
Lead the commissioning of new cryogenic systems, achieving full operational readiness within four weeks of delivery
Own and continuously improve Operational Equipment Effectiveness (OEE) across a growing fleet of cryostats: Quality, Performance, Availability
Improve cryogenic setup performance, including base temperature stability, coherence, ground loops, and dephasing, targeting near state-of-the-art results
Develop operational procedures, monitoring, and preventative maintenance strategies to ensure reliable 24/7 operation
Collaborate closely with hardware, RF, and measurement engineers to support demanding measurement campaigns
Deep, hands-on experience with cryogenic systems (dilution refrigerators) and their common failure modes
Strong practical background in RF measurements and cryogenic RF optimisation
Demonstrated experience scaling and operating complex technical infrastructure, ideally in an industrial, scale-up, or high-throughput R&D environment
Comfortable working under performance, uptime, and schedule pressure, making pragmatic engineering trade-offs
Proactive, detail-oriented, and motivated by turning advanced physics into reliable, repeatable engineering systems
We particularly welcome candidates with experience in industrial cryogenics, quantum hardware scale-ups, semiconductor test environments, or large experimental facilities.
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 competitive monthly salary, plus an 8% annual holiday bonus paid out each May
Pension that’s built to last - A future-proof pension plan that includes partner and dependent coverage. QuantWare covers 63% of the premium
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
Relocation support - If you’re moving to the Netherlands, we’ll make the transition seamless. We cover visa support, temporary housing in most cases, andhelp securing the 30% tax benefit for eligible candidates.
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 focus on well-being - We support your physical and mental energy through wellness initiatives that help you recharge and stay sharp
A connected team - We make space to celebrate wins together, with team events, offsites, and spontaneous moments that bring us closer
Financial clarity - Through our partnership with Equip, you’ll get tools and expert guidance to help you understand and optimise your total compensation
We’re an ambitious company, not only for our goals but also to become an even more diverse and inclusive team. We know this helps us with better decisions, more innovation, and strengthens our culture. In particular, we’d love to see more women in the quantum industry!
So if you’re a female talent, excited about this opportunity but don’t meet every single requirement, we still encourage you to apply.
As part of our recruitment process, candidates may be required to undergo pre-employment screening.
QuantWare is building the world’s most powerful quantum processors, and is today the highest-volume supplier of quantum processing units (QPUs) worldwide, with customers in more than 20 countries. Its unique VIO 3D scaling architecture is the only technology that unlocks MegaQubit-scale, ultra-high-speed quantum processors, delivering exponentially more performance per Watt per dollar invested. VIO paves the way for the hyper-scale quantum computers that will solve humanity's greatest challenges. The company was founded in 2021 by quantum computing experts Matt Rijlaarsdam and Alessandro Bruno as a spin-out from QuTech, a globally-leading quantum computing research institute, part of TU Delft in the Netherlands. The company has won multiple awards, including the Deloitte Technology Fast 50 Rising Star award in 2024. For more information, visit www.quantware.com and follow us on LinkedIn.
