Senior Electronics Engineer

About the team
The Sensing Engineering team at Q-CTRL transforms quantum research into deployable technologies that address real-world problems. We design, build, and field-validate an array of quantum sensors that support our key products, including Ironestone Opal - our solution for GPS-denied navigation.

You don’t need a background in quantum to make an impact here. We value strong engineering fundamentals, a product mindset, and a drive to solve the hardest engineering problems in quantum sensing today.

About the role

We are seeking a Senior Electronics Engineer to join the growing Quantum Sensing division at our laboratories in Sydney, Australia. This role will support the development of new quantum sensor prototypes designed for magnetic and inertial navigation.

As a Senior Electronics Engineer, you will provide technical leadership over hardware projects, taking responsibility for technical deliverables from the initial architecture to fieldable prototypes. The ideal candidate will be an accomplished analogue/mixed signal design engineer. Experience with optoelectronic devices is also desirable, though not essential. As a senior member of the hardware team, you will be expected to mentor engineers and technicians and drive continuous improvement of our hardware development practices.

Reporting to the Lead Engineer (Hardware), the Senior Electronics Engineer will contribute to our rapidly growing efforts to deploy software-ruggedised quantum gravimeters, accelerometers, and magnetometers.

What you'll be doing: :
•
Your role will focus on demonstrating quantum sensing for Aerospace, Defence, geophysical exploration and Earth observation.

•
Your primary goal will be architecting, miniaturising, and ruggedising bench-top prototypes for operation in the field.

•
You will manage the delivery of complex hardware prototypes, taking responsibility for the technical quality, performance, and reliability of the hardware.

•
As an individual contributor, you will be a domain expert in analogue and mixed signal design.

•
As a senior member of the sensing hardware team, you will be leading and mentoring hardware engineers and technicians.

•
Other duties within the Employee's skills and experience, or with reasonable training.

Ideally you'll have::
•
A Bachelors, Masters or PhD in Physics, Engineering or equivalent industry experience.

•
A demonstrated track-record of delivering high-quality analogue and mixed signal designs.

•
Optoelectronic experience is highly desirable, though not essential.

•
R&D experience working concurrently with scientists and engineers.

•
A strong desire to work with a world-leading team and a company that is fundamentally building the future of the quantum technology industry

About Q-CTRL
Q-CTRL is the global leader in AI-powered quantum control infrastructure software. We build the tools that make quantum technology useful, solving the hardest challenges in quantum computing and quantum sensing to deliver real-world impact.

Founded in 2017, we operate globally with offices in Sydney, Los Angeles, San Francisco, Berlin, and Oxford. Our teams bring together technical and multi-disciplinary expertise across the product lifecycle, and we’re hiring talent to help scale every part of the business. We work quickly to turn cutting-edge science into deployable technology.

In 2024 we raised US$113 million in Series B funding, the largest aggregate investment for a quantum software company. Six months later we delivered the first commercial quantum advantage with Ironstone Opal, our field-validated quantum navigation solution for defense and industry.

At Q-CTRL, we prioritize outcomes over hours. We offer flexibility, equity potential, and competitive benefits that reflect our high-performance culture. If you’re ready to help shape the future of quantum, we’d love to hear from you!
