Nanofabrication Engineer



At Oxford Quantum Circuits (OQC) we are building quantum computers to enable life-changing discoveries : from new drug modelisation to longer-lasting battery technology and portfolio optimisation. We are developing a cloud based quantum computer service – Quantum Computing as a Service (QCaaS) – to help our customers improve their operations and trailblaze new commercial and scientific approaches. 

Our team is composed of 12 people with various backgrounds in quantum physics, nanotechnologies, hardware, and software. We are all bound by the desire to put OQC at the forefront of the quantum revolution and build a technology with practical applications in mind. 


As a nanofabrication engineer, you will draw on your previous professional experience to develop and execute robust, precise process flows to build the superconducting circuits at the heart of our quantum processors. You’ll have the opportunity to build from our current technology that already produces devices with competitive quantum coherence, and you will have access to a network of state-of-the-art fabrication facilities in the area. You will be a vital member of a team of physicists and electrical engineers working to develop our device fabrication to produce quantum processors with world-leading performance.


  • Fabrication of superconducting devices for both R&D and product development 
  • Investigation and improvement of limiting factors to device coherence and fabrication precision 
  • Room-temperature test, characterisation and metrology of superconducting devices 
  • Design and implementation of procedures/tools to enhance throughput and precision
  • Work closely with device design teams to improve circuit performance
  • Help create, develop and maintain process documentation
  • Present work at internal meetings with clearly explained information



  • Masters or Ph-D in Physics, Applied Physics, material science or related field
  • 2+ years of experience in nanofabrication in a cleanroom environment, performing multi-step nanofabrication autonomously
  • Specific experience with the following processes:
    • Electron-beam lithography of precisely defined sub-micron features
    • Wafer-scale photolithography with micron-resolution
    • Deposition of uniform thin films
  • Proficiency in mask design and 2D CAD software
  • Experience with electrical probe measurements
  • Working knowledge of Python
  • Meticulous attention to detail
  • Highly adaptable, good communication and  interpersonal skills
  • Excellent collaborative problem-solving abilities that you are able to employ outside your own particular areas of expertise
  • Capability and eagerness to learn independently about new subject area(s) and underlying technologies


  • Experience in an R&D or industrial cleanroom
  • A good understanding of superconducting device physics
  • Electron-beam shadow evaporation of sub-micron Josephson junctions
  • Experience with thin film deposition and metrology of superconducting materials
  • Familiarity with advanced metrology techniques and equipment (SEM, AFM, FIB)
  • Experience with simulation software (ANSYS HFSS)


There will be a requirement for occasional travel throughout the UK and elsewhere abroad for meetings, conferences and engineering visits.


Attractive remuneration based on experience.
