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 Senior Systems Engineer to join the growing Sensing division at our laboratories in Sydney, Australia. This role supports the development of new quantum sensor prototypes and products, contributing to our growing efforts to deliver software-ruggedised quantum gravimeters, accelerometers, and magnetometers for GPS-denied navigation applications.
As a Senior Systems Engineer, you will provide technical leadership across the system design, integration, and validation lifecycle, ensuring that complex hardware and software subsystems operate together as a reliable, deployable system. You’ll apply structured systems engineering methods to transform cutting-edge scientific concepts into field-ready technology.
You will work closely with engineers and scientists to manage integration of subsystems spanning electronics, optics, mechanics, and software, and help validate complete systems in both lab and field environments. The ideal candidate will be an accomplished engineer with extensive experience in R&D environments, as well as aerospace or other mission-critical industries, and a passion for building technology that delivers real-world capability.
What you’ll be doing:
- Leading the systems development, integration, and validation of quantum navigation products for Aerospace, Defence, and other applications.
- Developing and maintaining system-level requirements, architecture, and interface definitions across multiple disciplines.
- Engaging with internal and external stakeholders to capture and refine system, product and user requirements, ensuring alignment and technical feasibility, and translate these into technical and functional requirements for cross-disciplinary teams to implement.
- Supporting business development and sales activities from a technical solutions perspective
- Collaborating with engineers and scientists across disciplines to integrate components into complex quantum sensor systems, resolving issues and ensuring subsystems work together reliably.
- Planning and executing integration, environmental and functional testing using a variety of tools and equipment
- Responsible for planning and executing 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.
- Documenting system configurations, results, and anomalies for reproducibility, root cause analysis, and quality assurance.
- Producing high-quality technical documentation including requirements, test plans & reports, interface diagrams, work instructions, operating manuals and other external documentation.
- Maintaining clear communication channels with project, product, engineering and research teams to report progress, assist in planning, and identify risks
- Contributing to continuous improvement of systems engineering practices, processes and tools
- Other duties within the Employee’s skills and experience, or with reasonable training.
Ideally you’ll have:
- A Bachelor’s degree or higher in a relevant field of engineering. Aerospace industry experience and recognised qualifications will be highly regarded.
- Formal systems engineering training and recognition (e.g. INCOSE certification or equivalent) will be highly regarded.
- R&D experience working concurrently with scientists and engineers from low to high TRL maturity.
- Proven experience in systems engineering, integration, and validation of complex hardware/software systems, ideally within aerospace, defence, or advanced sensing domains.
- Strong experience in requirements management, stakeholder engagement, and technical documentation.
- 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.
- Significant experience 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.
- Experience supporting field trials and flight testing autonomously, and readiness to travel for short deployments as needed.
- Experience supporting the transition from lab prototypes toward manufacturable designs is desirable, though not essential.
- Knowledge of aerospace quality systems, certification and qualification processes.
- Knowledge of documentation and configuration management practices, and experience using collaboration tools such as Jira and Confluence
- A strong desire to work with a world-leading team and a company that is fundamentally building the future of the quantum technology industry.
