Senior Digital Signal Processing Communications Engineer

Senior Digital Signal Processing Communications Engineer (AU)

Work with cutting edge technology, making the world a safer and more secure place. DroneShield (ASX:DRO) offers an opportunity to solve some of world’s most challenging technical problems in the Electronic Warfare, Artificial Intelligence and Machine Learning, RF sensing, Sensor Fusion and distributed systems. Working with high profile customers across militaries, government agencies, airports, critical infrastructure, law enforcement and many others.

With one of the largest listed defence company market capitalisations in Australia and having raised approximately $250m in 2024 alone, DroneShield is undergoing hypergrowth stage, fuelled by rapidly increasing use of drones for nefarious applications, from battlefield, to terrorism, to contraband delivery and commercial espionage.

This role will be based within a new DroneShield facility based in the Adelaide CBD. Droneshield has approximately 390 staff based within its Sydney headquarters and is scheduled to grow to 500 staff in Australia by end of 2026. Overseas on the ground presence includes Virginia (USA), Denmark, Germany and Dubai, as well as distributors in over 70 countries globally.

About the role

DroneShield is seeking a Senior DSP Communications Engineer with relevant experience to join the team in Adelaide, South Australia. The position will report to the principal Architect 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 primary focus of the role is to research and develop DroneShield’s next generation of Capabilities, working closely with ML/AI, Data Science, RF and infrastructure teams to innovate and enhance DroneShield’s world leading Anti-Drone technology.
