Hardware 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. 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.

• We are seeking a Hardware Integration Engineer to own the mechanical and electrical integration of Q-CTRL’s navigation and quantum sensing solutions onto UAS platforms, ensuring systems are correctly assembled, integrated, and ready for lab and field deployment
• You will collaborate with systems, software, hardware engineers across the US and HQ to integrate Q-CTRL sensors, controllers, auxiliary equipment, and other sensing systems onto operational platforms.
• You will bring up integrated hardware systems in laboratory environments and support field and flight testing
• The role involves hands-on build, debug, and modification work across mechanical and electrical domains
• As Q-CTRL’s sensing platforms mature, you will contribute to improving integration practices, documentation, and repeatability to support more efficient testing, field operations, and eventual scaling
• 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

• Own the mechanical and electrical integration of Q-CTRL sensors and auxiliary hardware onto UAS platforms, delivering reliable, flight-ready systems
• Develop and implement integration-specific mechanical and electrical components as required, including brackets, fixtures, cabling, and interface hardware
• Build and bring-up integrated hardware systems and execute bench, environmental, and functional testing
• Work closely with systems and software engineers to implement defined interfaces and ensure subsystems operate together reliably
• The role will involve intermittent domestic and international travel
• The role will involve regular liaison and communication across time zones, in particular with engineering teams at HQ in Sydney
• Plan and document integration builds, test configurations, results, and anomalies to support traceability and repeatability
• Liaise with suppliers and support procurement activities for prototype builds
• Assist maintaining equipment, consumables, and safe laboratory practices
• Contributing to continuous improvement of engineering practices, processes and tools
• Other duties within the Employee’s skills and experience, or with reasonable training

• A Bachelor’s degree in Mechanical Engineering, Electrical Engineering, Mechatronics, or related field
• Proven hands-on experience integrating complex electro-mechanical systems in aerospace, UAS, robotics, or advanced R&D environments
• Strong practical skills in prototype assembly, wiring, cable harness fabrication, and electro-mechanical build and rework
• Experience developing mechanical and electrical components using a variety of CAD tools; proficiency with tools, test and measurement equipment, basic fabrication, and experience with rapid prototyping
• Experience working closely with systems and software engineers to implement defined interfaces and integration requirements
• Exposure to low-level embedded software or driver development, and the ability to support or oversee minor driver modifications where required is advantageous but not essential
• Comfort operating autonomously in lab and field environments, including supporting time critical test and flight activities
• Experience supporting field trials or flight testing is highly desirable
• Familiarity with documentation, configuration management, and quality practices that support reproducible builds
