Senior Applied Modelling Scientist, Quantum Sensing

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 new Senior Modelling Scientist to help develop next-generation small-form-factor quantum magnetometers that are exquisitely sensitive, ultrastable, and able to operate reliably in harsh fielded environments. You will work closely with experts in quantum sensing to develop quantum magnetometry technology that will solve pressing challenges in aeronautical positioning and navigation, geophysical surveying, and magnetic anomaly detection.

A key focus of the role will be developing and implementing methods for removing magnetic and/or vibrational noise induced by the platform on which the quantum sensor is mounted. The algorithms, signal processing, automation, and data analytics you develop will inform the design, build, and operation of our quantum sensors for a given end-user application. The role will also involve developing novel software-layer control protocols and operating modes for optically-pumped atomic magnetometers that deliver step-change performance improvements in noisy operating conditions.

What you\\\’ll be doing

• Be part of an established and growing team focused on quantum sensing for a variety of industry sectors such as aerospace, defence, geophysical exploration and Earth observation;
• Perform time series analysis and develop platform and environmental noise compensation techniques using state-of-the-art digital signal processing and machine learning methods;
• Use data analytics to translate quantum sensor data streams into capabilities that solve pressing challenges for current and prospective end-users and customers;
• Perform essential research and development into novel quantum control solutions to enhance the performance of real-world quantum magnetometers;
• Develop novel theoretical models and numerical simulation tools suitable for assessing the performance of quantum sensors in real-world environments;
• Work closely with other Research and Engineering teams to deploy and validate your developed algorithms and sensing solutions on real quantum sensing hardware;
• Develop, document, and review high-quality software using Python;
• Share your insights and results with the broader Quantum Sensing Division, company, external stakeholders and customers through verbal presentations and written outlets (e.g. academic publications, technical reports, blog posts); and
• Liaise as needed with our academic and industry partners in order to perform the above duties and support new business and product development.
• Other duties within the Employee\\\’s skills and experience, or with reasonable training.

Ideally you\\\’ll have

• A PhD (or equivalent industry experience) in physics, electronic engineering, computer science, mathematics, or a closely related discipline.
• Experience in the theory, numerical modelling, and/or optimization of one or more of the following: optically-pumped magnetometry in warm atomic vapour cells; quantum atomic physical systems; atom interferometry; pulse-level optimisation and quantum control techniques, digital signal processing (e.g. adaptive filtering, phase-sensitive detection).
• Experience in time and frequency digital signal processing, e.g. adaptive filtering, Kalman filtering
• Contributing to a software system architecture with multiple components developed by different teams, adhering to best-practice software development precepts.
• Experience communicating technical results to a wide and varied audience.
• Experience with version control e.g. Git with CI/CD pipelines.
• Finally, you will have a strong desire to work with a world leading team and a company that is fundamentally building the future of the quantum technology industry

Desirable but not essential

• Experience in modern signal processing methods (e.g. Bayesian methods, particle filtering, sequential Monte Carlo methods);
• Experience with modelling geometric / gaussian optics
• Experience in sensor modelling and sensor signal processing, including data fusion
• Familiarity with the Python programming language for scientific computing.
• Familiarity with quantum and/or atomic physics at an undergraduate level.
• Experience working in a multidisciplinary team of physicists, engineers, software developers
