Quantum Twins, our simulation platform, provides unparalleled ability to model quantum systems, accelerating molecule and materials discovery.

This is SQC: building the future of computing while delivering quantum impact today.

About the role

We are hiring a Quantum Engineer to scale and advance SQC’s silicon multi-qubit processors. Working alongside quantum physicists, atomic fabrication engineers, software and hardware engineers, you’ll design, characterise, and optimise quantum processors based on atom spin qubits. You will operate advanced cryogenic and control systems to perform low-noise qubit measurements, validate device performance, refine qubit control and readout, and support the scale-up toward large error-corrected architectures. This role suits an experimentalist who is comfortable with coding, rigorous in data analysis, and motivated to translate quantum device physics into scalable processor performance.

Role responsibilities

• Operate and maintain cryogenic dilution refrigerator systems for advanced experiments on quantum processors

• Design and execute experiments to characterise the processor’s performance, from low-level device stability measurements to complex algorithmic benchmarking of scaled processors.

• Develop and maintain measurement and data analysis code.

• Analyse complex experimental datasets and extract clear performance metrics against defined requirements.

• 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.

• Maintain and support specialised laboratory and RF equipment

• Contribute to technical strategy and innovation by proposing and implementing new ideas and solutions.

• Stay abreast of industry trends and emerging technologies in quantum computing and quantum error correction.

Your experience

Essential:

• Bachelor’s, Honours, or Master’s degree in physics, quantum engineering, electrical engineering, or a related discipline.

• Demonstrated experience measuring multi-qubit or equivalent quantum devices in academic or industrial environments.

• Proficiency in coding using Python.

• Proven ability to conduct independent experimental research and drive projects to completion.

• Highly organised, detail-oriented, and able to maintain a strategic perspective in a dynamic start-up environment.

• 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, quantum engineering, electrical engineering, or a related discipline.

• Strong background in rf measurement techniques and microwave engineering.

• Hands on experience setting up and operating cryogenic dilution refrigerator systems

• Experience analysing and interpreting complex experimental datasets.

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.
