About us 

Silentium Defence (SD) is a growing deep tech business shaping the future of Australia’s ground and space surveillance capability. We specialise in the development of passive radar solutions for Defence and civilian customers. But what are passive radar solutions, you ask? 

Passive radar uses pre-existing sources of radio frequency energy (such as broadcast TV and radio waves), to track objects in an environment. It provides similar information to traditional radar systems but does not emit any RF signals. This means the user can maintain their situational awareness without advertising their presence. In essence, to ‘see without being seen’. 

Our technology is a game changer for Defence and we’re on a mission to create a new era in surveillance. We have a highly skilled, high-performing collaborative team and are looking for people as passionate as we are to grow our business and make impact on a global scale. What drives us every day is knowing we’re a small part of a bigger picture to protect our incredible country and its critical infrastructure assets for many generations to come. 

About the role 

We’re looking for an experienced Embedded Software Engineer (ESE) to support our Radar Algorithms Team Lead on a full-time, permanent basis. 

The ESE provides specialist software development skills, supporting the development and maintenance of SD’s back-end signal processing code, including interfaces to processing hardware. They play a critical role in ensuring that the code underpinning SD’s passive radar systems is efficient, tested, bug-free and maintained in accordance with best practice software development standards. 

Initially there will be a strong focus on refining the existing code base, ensuring that SD’s products are ready for market. This work will involve both new developments, taking design guidance from SD’s Radar Algorithms Team Lead, as well as optimisation of existing code.

The ESE will be developed into an authority on portions of SD’s signal processing code and become responsible for ensuring the quality and functionality in these areas. They will work closely with the Radar Algorithms Team Lead to determine how the back-end signal processing design is to be evolved as new features are added. 

What we’re looking for

Our ESE is confident and experienced in software development, capable of answering questions like: ‘how does this work?’, ‘why is this broken?’, and ‘how should we implement this new feature? They are a team player who is comfortable in mentoring junior engineers and providing code reviews of their peer’s work.
