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

We're hiring a Senior Software Engineer to help build the software backbone of Australia’s first scalable quantum computer. Working alongside quantum physicists and hardware engineers, you’ll design and implement software systems that interface with cryogenic instrumentation and control hardware, enabling precision measurement and manipulation of atom-based qubits.

This role sits within the Software Engineering team and reports to the Head of Software Engineering. You’ll play a key part in developing scalable, high-performance software solutions that support SQC’s roadmap to 100 qubit architectures, contributing to both experimental control and quantum algorithm integration.

Role responsibilities

• Develop and test software toolkits for hardware control (e.g. DACs, ADCs, signal generators)
• Build and optimise FPGA-based data acquisition and analysis applications
• Integrate quantum software stacks with third-party toolkits like Qiskit and Cirq
• Design automated pipelines for data handling and analysis
• Collaborate with researchers to develop control software for quantum experiments
• Work with hardware engineers to optimise measurement and benchmarking software
• Review commercial and open-source software for integration or partnership opportunities
• Write and maintain software documentation and manage version control
• Implement software testing frameworks and ensure code quality
• Lead delivery of software outcomes independently

Your experience

• Bachelor’s degree in Computer Science, Engineering, Physics or related field
• Extensive experience as a software engineer, ideally in research or hardware-adjacent environments
• Advanced proficiency in Python; familiarity with Rust is a plus
• Strong background in hardware communications and real-time programming
• Experience with multi-threaded and multi-process programming
• Familiarity with FPGA development and digital signal processing
• Exposure to quantum computing or quantum mechanics (academic or practical)
• Skilled in software testing, documentation and version control
• Comfortable working across Windows and Linux environments
• Strong interpersonal and communication skills; thrives in collaborative teams

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.
