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 Ironestone Opal - our solution for GPS-denied navigation.
You don’t need a background in quantum to make an impact here. We value strong engineering fundamentals, a product mindset, and a drive to solve the hardest engineering problems in quantum sensing today.
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.
You will work closely with systems and hardware engineers, and HQ software teams to bring up full sensor and navigation stacks, verify correct operation prior to flight, and manage data flow for analysis. As Q-CTRL’s quantum sensing technology matures, you will help establish robust deployment, testing, and release practices for hardware-in-the-loop and fielded systems.
You will join a growing global engineering team, working as part of a small US-based group supporting defense and aerospace programs, and operating at the intersection of software, hardware, and field operations.

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!
