Design Engineer, Integration & Access

SQC Silicon Quatum Computing; Sydney; On-site; AUD 120,000 - 180,000; Full time

Job summary

SQC Silicon Quantum Computing is hiring a Design Engineer for Integration & Access at our Sydney facility. You will own the user experience across the developer-facing surface—UI, SDKs, documentation and notebooks—balancing external and internal needs with depth in design and code.

You will collaborate with API/SDK engineers and researchers to create a clear interface atop a novel quantum system, and to ship production-grade frontends with accessible, scalable design.

Qualifications

• 4+ years designing and building web interfaces with depth in both design and code.
• Strong frontend engineering: TypeScript, a modern framework such as React, Vue or Svelte, CSS, and the browser platform.
• A portfolio of interfaces built for technical or specialist users.
• Interaction and interface design skills, including information architecture, prototyping and design systems.
• Data visualization in the browser, with D3, SVG, Canvas or WebGL.
• User research practice: choosing the right method, running it, and implementing the outcomes.
• Accessibility as a working habit, and awareness of the standards and legislation behind it.
• Comfort reading and writing Python well enough to work in notebooks and follow SDK code.
• Version control, testing and code review as part of your normal workflow.
• The ability to make a clear interface atop complex systems.

Responsibilities

• Own the user experience across the developer-facing surface: the Quantum Circuit UI, the SDKs, the documentation and the exploration notebooks.
• Design and build the web frontends, taking the work from research and wireframes through to production code.
• Design the visual language for quantum concepts that need it: circuits, device topology and qubit layouts, job state and queueing, calibration and qubit health, and the quantum results.
• Work with the engineers who own the API and SDK components to design a UI that is compelling and simple to use.
• Design the onboarding path that takes a developer from first contact to a running program, including the worked examples and execution documentation.
• Build and maintain a component library and design system so all interfaces stay consistent as the stack grows.
• Make the interfaces accessible and usable, including keyboard paths, contrast and screen reader support.
• Handle the visualisation and performance problems that come with large circuits, long job histories and dense result sets.
• Document design decisions and the reasoning behind them for team consistency and product quality.

Job description

2d ago , from SQC Silicon Quatum Computing

Silicon Quantum Computing (SQC) is at the forefront of global efforts to build the world’s first commercial-scale quantum computer, while delivering quantum-enhanced AI and simulation products to customers today.

Backed by over 25 years of technological excellence, SQC is a full-stack quantum computing company that leverages its proprietary manufacturing process to engineer atomic qubits in silicon with 0.13 nanometer precision. It is the most precise semiconductor manufacturing in the world, enabling systems with world-leading algorithmic fidelity, and a decisive advantage in the global quantum computing race.

Our products are commercially deployed and generating revenue. Watermelon, our quantum-enhanced AI system, is delivering superior results on real-world problems across energy, telecom and finance. Quantum Twins, our simulation platform, provides unparalleled ability to model quantum systems, accelerating molecule and materials discovery.

This is SQC: building the future of computing while delivering quantum impact today.

About the role

We are hiring a Design Engineer into Integration & Access, the team that owns everything a person or system touches on the way to our quantum computers: the frontend and its APIs, the SDKs for qubit and QML workloads, the worked examples, the documentation, and the exploration notebooks our researchers use. You will own how that feels to use, and you do both the design and the build.

The design problem is hard for reasons unrelated to visual craft. A user needs to see what their circuit will do, what the device can run, where their job sits in a queue, which qubits were healthy when it ran, and what a result with shot noise means. Most of that has no established design language.

Two audiences want different things. External developers want a program down and results back with as little quantum physics as the problem allows. Our own physicists want depth, control and the raw numbers. Serving both without building two products is much of the job.

Based at our Sydney facility, you will work closely with the engineers who own the API and SDK components, and with the researchers and customers who use what you build. This is a role for someone with real depth in both design and code, who can put a clear interface on top of a system that has never had one before.

Role responsibilities

• Own the user experience across the developer-facing surface: the Quantum Circuit UI, the SDKs, the documentation and the exploration notebooks
• Design and build the web frontends, taking the work from research and wireframes through to production code
• Design the visual language for quantum concepts that need it: circuits, device topology and qubit layouts, job state and queueing, calibration and qubit health, and the quantum results
