Senior Electronics Engineer

About us Founded in 2017, Q-CTRL has grown to become the global leader in quantum.  We're using control to solve the hardest problems facing quantum technology, improving hardware performance and accelerating pathways to useful quantum computers and other technologies. As a product-led company, we bring together diverse teams such as product, design, engineering and research to help achieve our mission of making quantum technology useful.  Join us to help shape the quantum future.
As one of the fastest growing companies in the quantum sector, we've had a number of key milestones:
- In November 2023, we announced an industry-first partnership with IBM Quantum Services, natively integrating our performance management software with all IBM quantum computers.  Building off of this relationship, in September 2024 we started offering two services via IBM's new Qiskit Functions Catalog as an inaugural partner. - Designed and moved our Global HQ offices and lab space into the first purpose-built (and award winning) commercial and research facility for a quantum technology company in Australia. - Continued to deliver real world outcomes across the quantum sectors, with our work with Australian Defence on software-ruggedized quantum sensing for navigation without GPS, as featured in the New York Times. - In October 2024, we announced our record breaking expansion of our Series B funding round to USD $113M, with $59M USD of new capital. - Grew our global presence to include Los Angeles, Berlin, and Oxford - as well as the recently announced office in San Francisco.
From educating the workforce on how quantum computing works, to building the next generation of quantum sensors, to delivering massive performance gains for end-users, it all starts with hiring the right talent. If you want to help us build the Quantum future, read on.
About the role We are seeking a Senior Electronics Engineers 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, through field trials, all the way to product certification. The ideal candidate will be an accomplished analogue/mixed signal design engineer. Experience with RF and optoelectronic devices is also highly 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 and eventual productisation.
• 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 at a Staff level. Note that as we have several open roles, we will also consider applicants at a Senior level.
• RF and optoelectronic experience is highly desirable, though not essential.
• R&D experience working concurrently with scientists and engineers.
• Experience taking designs from prototype to production, including design for manufacture and product certification.
• A strong desire to work with a world-leading team and a company that is fundamentally building the future of the quantum technology industry.
