About this job

We are expanding our team and are seeking a Senior Systems Modelling Consultant to lead the modelling and simulation activities on a range of defence and commercial satellite mission projects.

As the Senior Systems Modelling Consultant you will be responsible for modelling concept of operations, systems performance, and design reference missions in support of ground and space-based service-oriented architectures intended to service next generation space capabilities. Mission modelling is to be conducted in collaboration with design, development and study teams working on space-based systems and their ground support systems in Earth Observation, Communications, and Global and Regional Navigation system architectures.

As an experienced Model Based Systems Engineer (MBSE) you will have experience using multiple simulation tools including STK, Matlab etc.

This will give you the opportunity to work on multiple projects, experiencing the cutting edge of SatComs in both a commercial and Military environment.
