About the role
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.
Role responsibilities
Operate and maintain cryogenic dilution refrigerator systems for advanced experiments on quantum processorsDesign and execute experiments to characterise the processors, including device stability measurements, extraction of coupling strengths, performance benchmarksAnalyse complex experimental datasets and extract clear performance metrics against defined requirementsResearch, develop, and implement optimal characterisation and calibration protocolsDevelop and maintain measurement and data analysis codeDrive project-based development of new device designs and novel measurement capabilitiesCollaborate 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.
Your experience
Essential:Bachelor’s, Honours, or Master’s degree in physics, quantum or electrical engineering, or a related disciplineDemonstrated experience controlling and measuring qubits or other quantum devicesStrong data analysis skills and proficiency in coding using PythonSolid understanding of qubit control and readout conceptsExcellent communication skills, with the ability to explain complex technical concepts to diverse audiencesAbility to work effectively in multidisciplinary teams with shared ownership of outcomes
Desirable:PhD in physics, quantum engineering, or a related disciplineStrong background in RF measurement techniquesHands-on experience with dilution refrigerators and cryogenic measurement setups
