About the role

We are hiring a Quantum Engineer to support the rapid prototyping loop behind SQC’s atomic-precision quantum processing units (QPUs). Working closely with the QPU fabrication team, you will perform rapid characterisation and quality control of QPUs at cryogenic temperatures (4K). You will also help optimise and automate the screening setups and methods to improve throughput across the prototyping pipeline. This role suits someone with a materials/device characterisation background or process engineering background who enjoys rigorous, systematic work and wants to contribute to the world’s fastest manufacturing pipeline of quantum processors.

Role responsibilities:

• Perform characterisation of quantum devices at cryogenic temperatures
• Develop, standardise, and automate protocols for efficient device screening
• Develop and maintain the relevant characterisation code
• Produce and analyse high-quality measurement data
• Work closely with atomic fabrication, cleanroom, and measurement teams to continually improve the QPU prototyping loop
• Contribute to technical strategy and innovation by proposing and implementing new ideas and solutions.

Your experience:

Essential:

• Bachelor’s, Honours, or Master’s degree in physics, materials science, nanotechnology, quantum engineering, electrical engineering or a related discipline.
• Hands-on experience with materials characterisation or device characterisation in academic or industrial environments.
• Strong data analysis skills and proficiency in coding using Python.
• Highly organised, detail-oriented, and rigorous in documentation and process.
• 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.

Desirable:

• PhD in physics, materials science, nanotechnology, or a related discipline.
• Experience with cryogenic measurements of semiconductor or quantum devices.
• Familiarity with quality-control and yield methodologies from semiconductor manufacturing.

The recruitment process:

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. As part of our obligations to our clients, we require that successful candidates submit to background checks, including a National Police Check, Right to Work checks, as well as employment and qualifications verification.

Equal opportunity:

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.

Export controls:

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.

About SQC:

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. SQC is a high-accountability environment built on a simple principle: Every Atom Counts. If you’re looking to play a meaningful role in building the next frontier of computing, we’d love to hear from you.
