Quantum Engineer, Measurement

Job Description

About Us

\n

Silicon Quantum Computing is pioneering the future of quantum technology. As the world's first company to manufacture qubits with atomic precision, we're delivering quantum advantage today, not decades from now. Founded by Professor Michelle Simmons, one of the world's leading materials scientists, SQC has achieved major breakthroughs including the first single-atom transistor and the first integrated circuit built with atomic precision.

\n

Our Chair, Simon Segars, former CEO of ARM, brings deep global experience as we scale our technology and commercial impact. Our quantum machine learning chip, Watermelon, is already accelerating AI in ways classical systems can't match, generating significant revenue and working closely with multinational partners to solve complex problems with quantum solutions. SQC is a fast‐paced, high‐accountability environment where people grow quickly and contribute meaningfully. If you're excited by deep tech, ambitious about your career, and ready to help shape the future of computing, we'd love to hear from you.

About The Role

\n

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.
