Full Job Posting

About the role

Develop and validate cryogenic infrastructure connecting silicon quantum processors to classical systems.

Test wiring, interconnects, connectors, and quantum-classical interfaces inside dilution refrigerators.

The role suits an early-career engineer or physicist who enjoys careful, hands-on laboratory work.

Role responsibilities

  • Test and validate cryogenic wiring, attenuation stacks, interconnects, and connector solutions.
  • Develop and execute cross-talk testing protocols for high-density cryogenic signal delivery.
  • Assess noise, thermalisation, warming effects, and other impacts of cryogenic configurations on qubit performance.
  • Operate and maintain cryogenic dilution refrigerator systems and support monitoring and reliability.
  • Develop and maintain test and data-analysis code, documenting results against defined requirements.
  • Collaborate with hardware engineering and measurement teams on quantum-classical interfaces and refrigerator configurations.
  • Maintain and support specialised laboratory and RF equipment.

Essential experience

  • Bachelor’s, Honours, or Master’s degree in physics, electrical engineering, quantum engineering, or a related discipline.
  • Hands-on laboratory experience in cryogenics, RF or microwave test and measurement, or low-temperature physics.
  • Proficiency in Python coding.
  • Strong organisation, attention to detail, and rigour in testing and documentation.
  • Excellent communication skills for explaining complex technical concepts.
  • Ability to work effectively in multidisciplinary teams with shared ownership of outcomes.

Desirable experience

  • PhD in physics, electrical engineering, quantum engineering, or a related discipline.
  • Hands-on experience setting up and operating cryogenic dilution refrigerator systems.
  • Strong background in RF measurement techniques and signal integrity.
  • Experience measuring qubits or other cryogenic quantum devices.
  • Familiarity with cryogenic wiring, attenuation, and filtering design for quantum computing systems.

Recruitment and checks

  • The recruitment process is expected to include three to four interviews.
  • Successful candidates may undergo background, right-to-work, employment, and qualifications checks.
  • The position may involve access to export-controlled information or technology and may require eligibility assessment.
