Quantum Engineer - Characterisation and Calibration

We are hiring a Quantum Engineer to push the performance of SQC’s atomic-precision quantum processors through world-class qubit calibration and control. Working closely with the full-stack team, you will characterise and calibrate atomically engineered multi-qubit processors to achieve the best possible stability and speed from our qubits. Using tailored dilution refrigerator measurement setups, you will design, execute, and automate protocols to efficiently extract the critical device parameters for each generation of quantum processors, directly contributing to the world’s fastest manufacturing pipeline of quantum processors. This role suits someone with a nano-device background who combines deep experimental intuition with strong engineering discipline.

• →Operate and maintain cryogenic dilution refrigerator systems for advanced experiments on quantum processors
• →Design and execute experiments to characterise the processors, including device stability measurements, extraction of coupling strengths, performance benchmarks
• →Analyse complex experimental datasets and extract clear performance metrics against defined requirements
• →Research, develop, and implement optimal characterisation and calibration protocols
• →Develop and maintain measurement and data analysis code
• →Drive project-based development of new device designs and novel measurement capabilities
• →Collaborate effectively with cross-functional teams (atomic fabrication, cleanroom, theory, hardware, software) to ensure alignment on project goals and deliverables.
• →Contribute to technical strategy and innovation by proposing and implementing new ideas and solutions.

• Bachelor’s, Honours, or Master’s degree in physics, quantum or electrical engineering, or a related discipline
• Demonstrated experience controlling and measuring qubits or other quantum devices
• Strong data analysis skills and proficiency in coding using Python
• Solid understanding of qubit control and readout concepts
• Excellent communication skills, with the ability to explain complex technical concepts to diverse audiences
• Ability to work effectively in multidisciplinary teams with shared ownership of outcomes

• PhD in physics, quantum engineering, or a related discipline
• Strong background in RF measurement techniques
• Hands-on experience with dilution refrigerators and cryogenic measurement setups

For roles at SQC, expect 3-4 interviews, meeting a few members of the team and focusing on your core eligibility for the role, your skills and how they align, and finally your values and how they align. We'll give you a more specific runthrough if you're successful in making it to the first interview.

SQC is an equal opportunity employer. We value diverse perspectives and experiences, and encourage applications from candidates who may not meet every listed requirement. If you’re excited about the role and believe you can contribute, we encourage you to apply.

This position may require access to export-controlled information or technology. Employment may be subject to applicable export control laws and may require eligibility assessment based on factors such as nationality, citizenship, or residency, and, where necessary, obtaining relevant export licenses or approvals.

SQC was founded by renowned physicist and materials scientist Michelle Simmons, who pioneered the field of atomic electronics, including the development of the world’s first single-atom transistor and the first integrated circuit built with atomic precision. Our Chair, Simon Segars, former CEO of Arm, is a leader in the semiconductor industry and was instrumental in developing the processors that powered the mobile computing revolution.
