Electronics Engineer

Diraq is redefining scalable quantum computing by enabling billions of qubits on a single chip-far beyond the hundreds available today-to unlock practical, commercial quantum applications. We are building a full-stack quantum computing company, delivering quantum hardware and software as a cloud-accessible service.

We are seeking an Electronics Engineer to support the development, integration and validation of advanced cryogenic test infrastructure used to evaluate next-generation quantum computing hardware.

This role combines electronic design, hardware integration, laboratory testing and systems engineering. You will design and maintain reliable, high-performance test platforms that enable the characterisation of quantum devices operating at cryogenic temperatures. Working within a multidisciplinary team of engineers, scientists and researchers, you will contribute to sophisticated measurement systems at the forefront of emerging quantum technologies.
