Applied Modelling Scientist

Job Description

Job Title: Applied Modelling Scientist, Quantum Sensing. Location: Sydney, Australia; Oxford, United Kingdom

You will join a team of specialists in atomic physics, signal processing, & quantum control, working to create sensing solutions with real-world applications in aerospace, defence, geophysics, and Earth observation.

Duties:

• Conduct research and modelling to develop new methods for noise reduction in quantum sensors caused by magnetic and vibrational interference.
• Perform time-series analysis and implement digital signal processing and machine learning techniques for environmental noise compensation.
• Use data analytics to transform sensor outputs into actionable insights for practical industry applications;
• Develop theoretical models and numerical simulations to assess sensor performance in real-world environments.
• Create and optimize control algorithms for optically-pumped atomic magnetometers to improve stability and precision;
• Work closely with engineering teams to deploy and validate models and algorithms on operational quantum sensing hardware.
• Write and review high-quality software in Python following modern development practices such as version control and CI/CD pipelines.
• Share findings through presentations, technical papers, and reports to internal teams and external partners.
• Collaborate with academic and industry partners to support R&D, product development, and customer needs.

Qualifications:

• PhD or equivalent experience in physics, electronic engineering, computer science, mathematics, or related field.
• Strong background in quantum atomic systems, magnetometry, or interferometry;
• Experience with signal processing, adaptive filtering, Kalman filtering, and time-frequency domain analysis.
• Skilled in numerical modelling, optimization, and algorithm development.
• Experience working with software architecture, version control (Git), and CI/CD pipelines;
• Excellent communication skills and ability to present results to both technical and non-technical audiences.
• Desire to work with a global leader in quantum control technology and contribute to real-world impact.

Preferred:

• Knowledge of Bayesian methods, particle filtering, or sequential Monte Carlo techniques.
• Experience in sensor signal processing and data fusion.
• Familiarity with geometric or Gaussian optics modelling;
• Experience working in multidisciplinary teams across physics, engineering, and software.

Benefits and Instructions:

• Full-time permanent hybrid role based in Sydney or Oxford.
• Competitive compensation with opportunities for research and industry collaboration;
• Work within a world-class team shaping the future of quantum sensing and quantum control infrastructure.
• To apply, submit your application through Q-CTRL’s careers portal with relevant academic or professional references.
