Our products provide ultra-high performance, real-time detection, tracking, identification and targeting of dynamic aerial threats.

• A solid understanding of computer vision techniques and machine learning principles 

• A creative problem solver who knows when to ask questions and how to manage their time effectively 

• Reliable, adaptable, and self-aware - someone who fits naturally into a collaborative engineering team 

What you’ll get:  

• Work on seriously cool projects. From tracking rogue drones to developing world-first interception tech, our projects are anything but ordinary. You’ll work on cutting-edge systems that are making waves across global defence and security sectors. 
• Autonomy to make an impact. At OpenWorks, you won’t be a small cog in a big machine. We value initiative and trust our engineers to take ownership, solve problems creatively and drive their own work forward with real responsibility.
