Lead Cryogenic Engineer
About Us
QuantWare is the world's leading manufacturer of superconducting quantum hardware. As a hyper-growth scale-up with a global customer base, our mission is to accelerate the advent of the quantum computer. We push the boundaries of what's possible in our field. We work on making the world’s largest quantum processors as fast as possible.
At QuantWare, we’re not just producing quantum hardware for the hyperscalers of tomorrow; we’re working on technology that will change the world. To make that ambition a reality, we need exceptional people who drive real impact. 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.
What You’ll Be Doing
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
Your Profile
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.
