Senior Quantum Control Engineer - Quantum Sensing at Q-CTRL

Pyrmont, NSW

Apply to Q-CTRL

Quantum technology is likely to be as transformational in the 21st century as harnessing electricity was in the 19th. Quantum computing in particular promises to completely disrupt the way we process information - transforming previously uncomputable problems into manageable ones.

If you build or use quantum hardware, Q-CTRL provides the critical enabling software and professional services to help you achieve maximum performance.  We empower our customers to realise the true potential of quantum tech, combining modern product design and engineering with state-of-the-art quantum control techniques.

Backed by globally renowned investors including Square Peg, Sierra Ventures, and Sequoia Capital, we recently completed our Series A funding round, securing an additional AU$22M to advance our work.

We are seeking a senior quantum control engineer with experience in quantum sensing. Specific areas of interest include optical magnetometry, atomic Gravimetry, and inertial navigation. Preference will be given to candidates with experience in sensor operation, automation, and data fusion. An understanding of dominant performance limits in fieldable systems is desirable.

You will join a growing team focused on quantum sensing for defence and aerospace. Our projects will leverage the deep expertise of the Q-CTRL quantum control engineers and will involve collaboration with hardware development teams.

What you'll do

  • Develop control solutions for quantum sensors based on cutting edge hardware (including atomic interferometers and magnetometers)
  • Interact with hardware partners in quantum sensing for the deployment of control techniques for sensor operation and data fusion
  • Analyse sensor performance in realistic environments and apply optimisation and machine learning techniques for both performance enhancement
  • Develop publicly available and high quality software using Python
  • Collaborate with your colleagues in the Quantum Control Engineering and Software Engineering teams
  • Explain and document sophisticated control solutions in accessible language
  • Consult with the Lead Quantum Control Engineer, stakeholders and the broader team on decisions for all new products and features
  • Interact with customers as needed to deliver solutions which help them achieve their goals

We would love to hear from you if

  • You have a PhD in Physics, Engineering or a closely related discipline.
  • You have experience in sensor operation, automation, and data fusion.
  • You have an understanding of dominant performance limits in fieldable systems (desirable)


At Q-CTRL, you can make a difference from day one - you won't be just a cog in the machine. You will work in a fascinating industry where you get to be a part of the 21st century’s most disruptive technology transformation. 

You'll get to live the startup life without the startup wages: we offer competitive salaries and potential equity options. We also embrace flexible work hours - worry about your global impact, not a rigid work schedule. Headquartered in WeWork, our team gets to enjoy the perks of this vibrant startup hub (private and communal work spaces, lunch and learns, workshops, yoga classes, run club, community gatherings, weekly breakfast, free flowing coffee/beer and much more). We are looking for people as excited as we are about building the quantum future. Join us!
