Senior Software Engineer, Skyral Modelling & Development


Join our defence and national security business and you’ll be helping users plan and train to meet the most complex security threats in the world. Working alongside experts in AI and Machine Learning, computational modelling and distributed systems, you’ll be putting multiplayer technology to life-saving use.
We believe that the grand scale adoption of synthetic environments by governments and international institutions will give rise to a powerful capability for global good.  New levels of whole force preparedness and the harnessing of previously unattainable foresight will ultimately prevent states from stumbling into war; contributing to a more secure and prosperous world and bringing about the end of unnecessary human conflict.
Improbable Defence develops a software platform that enables the creation of these synthetic environments, with the aim of providing truly full spectrum synthetic training and planning platforms.  This will ultimately make defence users more effective when deployed on modern, multi-domain operations and plummet the cost of military preparedness.
