Description

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.

- Strong documentation discipline and attention to detail.

Desirable Experience

- Electronics or test infrastructure for cryogenic, quantum computing, semiconductor, RF, microwave or low-noise measurement applications.
- Signal integrity, impedance-controlled PCB design, RF transmission lines, grounding, shielding, filtering and electromagnetic compatibility.
- Cryogenic design constraints, including thermal loading, material selection, thermal contraction, connector reliability and temperature-dependent electrical behaviour.
- Automated test, data acquisition or data analysis using Python, MATLAB or similar tools.
- Design for manufacture, component selection, supplier engagement and prototype production.
- Engineering change control, document management and laboratory safety practices.

Personal Attributes

- Practical and comfortable working directly with hardware in a laboratory setting.
- Methodical and evidence-based when diagnosing technical issues.
- Able to manage competing priorities and progress work with a high degree of ownership.
- Strong written and verbal communication skills.
- Collaborative and comfortable working within a multidisciplinary engineering and scientific team.
- Curious, adaptable and motivated to develop knowledge of cryogenic and quantum computing technologies.
