About Us 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. 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. We’re 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 SQC is embarking on an ambitious journey to develop Cryo-CMOS chips that will enable the miniaturisation of electronic hardware within our quantum computers. This advancement is crucial for building larger and more complex quantum systems, ultimately supporting our vision of achieving a utility-scale quantum computer.

As a Senior RF IC Design Engineer, you will be instrumental in this pioneering effort, contributing your expertise to the design, simulation, and validation of integrated circuits at cryogenic temperatures that will drive the next generation of quantum computing hardware.

Strong analog and RF IC design skills are essential to address the challenges of Cryo-CMOS design, such as working with early, less-defined models and designing experiments to improve understanding of cryogenic temperature effects.

Role Responsibilities

• Design, simulate, and validate analog and mixed-signal circuits tailored for quantum computing systems.
• Develop and optimise low-temperature RF/microwave circuits – including LNAs, mixers, PLLs, LOs, and PAs – using CMOS technology.
• Perform advanced simulations, including Monte Carlo and corner case analyses, to ensure robust circuit operation.
• Participate in IC design planning, risk assessment, and performance benchmarking.
• Operate measurement equipment and resolve issues related to circuit evaluation and testing.
• Prepare comprehensive documentation of designs, simulation outcomes, and measurement data for internal and external stakeholders.
• Collaborate closely with internal teams and external partners, ensuring seamless integration between IC and module design efforts.

Your experience Essential Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Microelectronics, or a related discipline.
• Significant hands-on experience with Cadence Virtuoso, Spectre/SpectreRF, Calibre DRC/LVS/PEX.
• In-depth expertise in IC design across various silicon technologies, including SOI.
• Strong foundation in transistor-level circuit design.
• Proven ability to design RF building blocks such as LNAs, mixers, PLLs, LOs, PAs, and RF switches in the 1-10GHz regime.
• Proficiency in refining simulations to closely match silicon performance.

Desirable Familiarity with:

• ANSYS EM tools such as HFSS or RaptorX.
• RF-oriented processes (e.g., SiGe, GaAs, MMIC) and GF 22FDX
• Optoelectronic drive circuits
• Hands-on experience with cryogenic testing and measurement techniques.
• Understanding of semiconductor device physics and low-temperature circuit operation.

The recruitment process For roles at SQC, expect 3-4 interviews, meeting a few members of the team and focusing on your core eligibility for the role, your skills and how they align, and finally your values and how they align. We'll give you a more specific runthrough if you're successful in making it to the first interview.

As part of our obligations to our clients, we require that successful candidates submit to background checks, including a National Police Check, Right to Work checks, as well as employment and qualifications verification. We won't contact anyone until we're confident there's a fit between SQC and yourself.

How To Apply The best and simplest way is to apply directly here, rather than messaging anyone on the SQC team directly. If you have any questions that you'd like answered before committing to applying, please feel free to email us at careers@sqc.com.au.

Please note This position may require access to export-controlled information (ECI) subject to EAR and ITAR. Final employment decision is contingent upon satisfactory completion of export control screenings and obtaining any necessary export licenses or approvals, based on nationality, citizenship, and other factors considered by applicable export control regulations.
