Software Integration Engineer

About the team

The Sensing Engineering team at Q-CTRL transforms quantum research into deployable technologies that address real-world problems. We design, build, and field-validate an array of quantum sensors that support our key products, including Ironstone Opal - our solution for GPS-denied navigation.

About the role

We are seeking a Software Integration Engineer to own the deployment, configuration, and operational readiness of Q-CTRL’s navigation and quantum sensing software on UAS platforms. This role is hands-on and execution focused, ensuring rapidly evolving software developed at HQ is correctly integrated, configured, tested, and run on real platforms in lab and field environments.

What you'll be doing:

• Own software deployment and configuration on UAS platforms, ensuring alignment with fast-moving HQ software releases.
• Bring up and verify full sensor, driver, transport, and navigation stacks prior to lab tests and flight operations.
• Act as the on-site software authority during field trials, diagnosing and resolving software and system-level issues.
• Retrieve, validate, and organize test and flight data for delivery to HQ software and science teams.
• Work closely with systems, hardware, and HQ software engineers to close integration gaps.
• Contribute to improving deployment workflows, testing, and CI/CD processes for hardware-integrated software.
• Lead strategic communication with internal teams and external partners.
• Other duties within the Employee’s skills and experience, or with reasonable training.

Ideal qualifications:

• A Bachelor’s degree in Software Engineering or a related field
• Experience deploying and operating software on Linux based embedded, robotics, or UAS platforms.
• Experience with numerical software and/or algorithm development, with an emphasis on inertial navigation, state estimation, data fusion, or optimization.
• Proficiency with systems programming language such as C, C++, Rust and Python
• Experience setting up and maintaining continuous integration systems
• Familiarity with DevOps practices applied to hardware systems
• Experience working with sensor drivers, middleware, and data transport layers.
• Ability to work effectively across software, hardware, systems and research teams.
• Experience in defense, aerospace, autonomy, robotics, or navigation systems is highly desirable.

About Q-CTRL

Q-CTRL is the global leader in AI-powered quantum control infrastructure software. We build the tools that make quantum technology useful, solving the hardest challenges in quantum computing and quantum sensing to deliver real-world impact.

Founded in 2017, we operate globally with offices in Sydney, Los Angeles, San Francisco, Berlin, and Oxford. Our teams bring together technical and multi-disciplinary expertise across the product lifecycle, and we’re hiring talent to help scale every part of the business. We work quickly to turn cutting-edge science into deployable technology.

In 2024 we raised US$113 million in Series B funding, the largest aggregate investment for a quantum software company. Six months later we delivered the first commercial quantum advantage with Ironstone Opal, our field-validated quantum navigation solution for defense and industry.

At Q-CTRL, we prioritize outcomes over hours. We offer flexibility, equity potential, and competitive benefits that reflect our high-performance culture. If you’re ready to help shape the future of quantum, we’d love to hear from you!
