Staff Software 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 Staff Software Engineer to join our quantum sensing team, working on our next-generation inertial quantum sensors. Working closely with our team of engineers and physicists, you will use your traditional software development skills (a quantum background is not necessary) to architect, design and test new sensing technologies. Specifically, you will be responsible for the software used in a quantum inertial sensor, implementing physics-based control strategies that optimise sensor robustness and performance.

You will support continuous miniaturisation and improvement of the technology for deployment in mobile applications. You will join a growing team focused on quantum sensing for defence and aerospace, and work with experts in cold-atom interferometry, magnetometry, and inertial navigation to develop state-of-the-art technology.

• Work with a team of engineers and scientists to architect and develop software solutions to unique quantum sensing and quantum control problems.
• Work with hardware engineers to bring-up and improve hardware designs by providing software expertiseWork with the broader quantum sensing team to identify and resolve issues that arise during the development of lab-based and field-deployable prototypes.
• Support quantum sensing field trials with key industry partners.
• With the support of our infrastructure experts, own continuous integration and testing of the firmware, including hardware-in-the-loop test fixtures.
• Work with other software engineers to continuously refine and improve development practices and processes.
• As needed, lead and coordinate project teams and contribute to project management activities.
• Other duties within the Employee's skills and experience, or with reasonable training.

• Proficiency writing firmware for embedded real-time control systems using a systems programming languages such as C, C , or Rust.
• Experience working in an R&D environment, collaborating with established engineering teams and research scientists.
• Experience using Python to interface with embedded systems.
• Preference will be given to candidates who have deployed systems in aircraft/defence applications.
