Software Engineer

About us

Founded in 2017, Q-CTRL has grown to become the global leader in quantum control infrastructure software. 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. We believe that working in deep tech domains like quantum provides an opportunity to upskill whilst applying existing knowledge and practices to new markets.

As one of the fastest growing companies in the quantum sector, we’ve had a number of key milestones:

- In October 2024, we announced our record breaking expansion of our Series B funding round to USD $113M, with $59M USD of new capital.

- 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.

- Grew our global presence in Los Angeles and Berlin, and expansion into the UK, recently opening up a new office in Oxford.

- 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.

From educating the workforce on how quantum computing works, and 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 Software Engineer to develop applications on our Linux control platform for our quantum accelerometers and magnetometers in order to optimize sensor performance online, execute navigation and map-matching algorithms, efficiently log and process operational data, interface with Q-CTRL’s cloud services, and generally assist with scientific exploration in the field of quantum sensing. You’ll work closely with research scientists who are developing sensing and navigation algorithms to produce robust and computationally efficient implementations suitable for deployment on mobile platforms (e.g. ships, planes, drones) operating in real-world environments.

As the maturity of our quantum sensing technology increases you’ll drive a culture of software development best practices, testing, and release management to ensure Q-CTRL’s quantum sensing teams are delivering the highest quality software possible.

You will join a growing team focused on quantum sensing for defence and aerospace, and work with experts in fields such as cold-atom interferometry, magnetometry, and inertial navigation to develop state-of-the-art technology.

• Own the development, integration, and support of software applications employed in Q-CTRL’s quantum sensors and auxiliary hardware.
• Be responsible for the design, implementation, and testing of software applications used in the optimization of next generation quantum sensing, navigation, and map-matching technology.
• Integrate our quantum sensing solutions with Q-CTRL’s cloud services.
• Liaise with scientists to develop solutions to issues that arise during research and development in the lab.
• Work on critical quantum sensing field trials with key industry partners.
• Own and improve continuous integration systems and software testing infrastructure.

• Experience working in a research environment whilst collaborating with established engineering teams and research scientists.
• Experience in writing numerical software or algorithm development, with an emphasis on inertial navigation, state estimation, data fusion, or optimization.
• Proficiency with a systems programming language such as C, C++, or Rust.
• Proficiency in using Python tools and packages for data processing.
• Experience setting up and maintaining continuous integration systems.
• Demonstrated leadership in driving software development best practices in engineering teams.
