Senior Systems Technician at Q-CTRL, Sydney. A senior-level full time position in the Sensing R&D; team, listed under research.

About the team

The Sensing R&D; 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.

Responsibilities

- Supporting the development, integration, assembly and testing of quantum sensing prototypes for Aerospace, Defence, and other applications.
- Assembling, wiring, and troubleshooting prototype systems, including PCBAs, cable harnesses, opto-mechanical components and laboratory test rigs.
- Performing integration, environmental and functional testing using oscilloscopes, spectrum analyzers, dataloggers, power supplies, and other equipment.
- Collaborating with engineers and scientists across disciplines to integrate electronic and mechanical components into complex quantum sensor systems, resolving integration issues and ensuring subsystems work together reliably.
- Supporting flight and field trials, including equipment preparation, logistics, and on-site setup, operation, and troubleshooting.
- The role will involve intermittent domestic and international travel,



which may amount to several months per year to support field activities.
- Assisting with test planning and data collection, documenting configurations, results, and anomalies for reproducibility and traceability.
- Documenting builds, testing, wiring diagrams, and lab test procedures to ensure reproducibility and quality.
- Supplier liaison and procurement for prototype builds.
- Maintaining equipment, consumables, and secure laboratory practices.

Nice to Have

- A diploma, associate degree, or equivalent industry qualification in electronics, mechatronics, avionics, or a related field. Aerospace/Avionics industry recognised qualifications will be highly regarded.
- A demonstrated track-record of hands-on electro-mechanical assembly and test at a Senior level.
- Aerospace R&D; experience working concurrently with scientists and engineers.
- Strong practical skills in soldering (through-hole and fine-pitch SMT), cable harness fabrication, and prototype assembly. Industry recognised standards such as IPC will be highly regarded.
- Excellent written and verbal communications skills and experience working with a variety of stakeholders including technical, commercial, and operational staff including external partners and customers.
- Familiarity with system integration, instrumentation, and environmental testing
- Ability to interpret schematics, mechanical drawings, and wiring diagrams, and to identify and resolve system-level issues.
- Proficiency with test and measurement tools such as multimeters, oscilloscopes, spectrum analysers, and data acquisition systems.
