About The Role and Team

Quantum Motion is a fast-growing quantum computing scale-up based in London founded by internationally renowned researchers from UCL and Oxford University with over 40 years’ experience in developing qubits and quantum computing architectures. Bringing together state-of-the-art cryogenic facilities and an outstanding interdisciplinary team, we are developing quantum processors based on industrial-grade silicon chips, with the potential to radically transform computing power in areas such as materials modelling, medicine, artificial intelligence and more.

Our Team

Since 2021 our team has been listed every year in the “Top 100 Startups worth watching” in the EE Times in 2021 and 2022, and our technology breakthroughs have been featured in The Telegraph, BBC and the New Statesman. Our founders are internationally renowned researchers from UCL and Oxford University who have pioneered the development of qubits and quantum computing architectures. Our chairman is the co-founder of Cadence and Synopsys, the two leading companies in the area of Electronic Design Automation. We’re backed by a team of top-tier investors, and we have recently closed our Series C funding of $160 million.

We bring together the brightest quantum engineers, integrated circuit (IC) engineers, quantum computing theoreticians and software engineers to create a unique, world-leading team, working together closely to maximise our combined expertise. Our collaborative and interdisciplinary culture is an ideal fit for anyone who thrives in a cutting-edge research and development environment focused on tackling big challenges and contributing to the development of scalable quantum computers based on silicon technology.

This is a rare and exciting opportunity to be an employee at a scale-up shaping the future of quantum computing. There are vast opportunities for professional growth and to make an impact within the company.

Our team of 100+ is based across London, Oxford, San Sebastián and Sydney, with our primary hub in Islington (London).

Functions of the Role

We’re looking for a visionary and hands-on 3D Integration and Advanced Packaging lead to bridge the gap between cutting-edge silicon spin qubit devices and scalable quantum systems.

In this role, you will build and lead a team to drive the R&D of complex, multi-chip modules utilising TSVs and microbumps, optimised to operate at millikelvin temperatures. This is a rare and exciting opportunity to solve the industry’s toughest interconnect bottlenecks and shape the physical architecture of next-generation quantum processors.

  • Recruit, mentor, and lead a high-performing team of packaging, signal integrity, materials, and quantum integration engineers.
  • Drive the strategy, design, and rapid prototyping of 3D integrated circuits and multi-chip quantum modules.
  • Ensure all packaging architectures and interconnects can withstand thermal cycling down to millikelvin regimes without delamination or performance degradation.
  • Own relevant operations with external foundries, OSATs, and research partners. Seamlessly transfer novel packaging designs to external manufacturing lines.
  • Serve as the critical link between design, process integration, cryo R&D, and quantum hardware teams to co-optimise the electrical, thermal, and mechanical design.
  • Balance rapid R&D prototyping with a rigorous, parallel focus on yield improvement, failure analysis, and long-term reliability.

Experience - Essentials

  • Master’s or PhD in electrical engineering, materials science, physics, microelectronics, or related field.
  • 7+ years deep technical experience in 3D integration, specifically with TSVs, fine-pitch microbumps, flip-chip bonding, and/or multi-chip modules.
  • Proven track record or building, scaling, and managing engineering teams in high-tech, fast-paced environments.
  • Strong experience managing technical transfers and working closely with external semiconductor foundries or advanced packaging facilities.

Experience - Desirable

  • Proficiency with industry-standard simulation tools (e.g., Ansys HFSS/Q3D, Cadence) to model signal integrity, thermal stress, and mechanical behaviour.
  • Direct experience with cryogenic electronics.
  • Background or strong familiarity with solid-state quantum mechanics, silicon spin qubits, or semiconductor physics.
  • Knowledge of materials behaviour (superconductors, low loss dielectrics) at extreme temperatures.

Benefits

  • Be part of a creative, world-leading team
  • Competitive salary and share options scheme
  • Contributory pension scheme
  • Group private medical insurance scheme
  • Life Assurance
  • Cycle-to-work Scheme
  • Central London location

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
