▷ 3 Days Left Principal RF Engineer

About the role

DroneShield is seeking a Principal RF Engineer with relevant experience to join the team in Adelaide, South Australia. The position will report to the Embedded Hardware Manager within the Sensors and Effectors Team.

The Sensors and Effectors team at DroneShield is focused on providing fully operational and qualified modular devices to enable new product development of high-end RF based sensors and effectors. These modules are re-used across various product configurations including man-portable, vehicle mounted and fixed site. Key technical challenges for the electronics aspect of these modules include the design of complex wide-band RF circuitry, high speed digital interface and high-power radio frequency output. DroneShield designs and builds the full signal chain from signal generation to antenna.

The expectations of this role will be focussed on the architecture of the system and detailed design, working with other teams to ensure the next generation product remain class leading. This will include inputs to the next generation electronics architecture, guiding engineers on SCH/PCB design implementation, reviewing validation test plan development, troubleshooting existing design problems and hardware issue root-case analysis and resolution.

Responsibilities

- Self-management of workload, methods and workflow to meet key business objectives.
- Schematic and PCB design using Altium, including contribution to component database and document templates.
- Expert knowledge with test equipment for validation of high-speed digital and RF interfaces, including training younger engineers for correct usage.
- Manufacturing test specification design and support for production setup & debugging.
- Hardware design validation planning and execution on both a modular and system level.
- Employing and developing sound industry practices for documentation and QC.
- Mentoring and training of junior engineers
- Design and develop RF jamming systems specifically tailored for countering unmanned aerial system (UAS) threats.
- Optimise RF system performance by analyzing and resolving interference issues, improving signal quality, and increasing range and reliability.
- Work closely with the product development team to integrate jamming technology into portable, vehicle-mounted, and stationary anti-drone systems.
- Stay up-to-date with the latest RF technologies and industry trends to ensure that designs are innovative and competitive.
- Stay current with the evolving landscape of drone technology and counter-drone measures to ensure that jamming systems remain effective against new threats.
- Collaborate with cross-functional teams, including hardware engineers, software engineers, and project managers, to ensure that RF design considerations are integrated into the overall system design from the outset.

Qualifications, Experience and Skills
