Principal Systems Engineer – Software Simulation

I offer a competitive salary of up to £75,900, dependent on my skills and experience. Joining our Simulation and Training sector at Broad Oak Works Portsmouth, I will work on our MIMESIS product, which provides a battlespace simulation of the maritime world, accurately modelling the movement and behaviour of ships, submarines, and other platforms. As a System Technical Lead within the MIMESIS team, I will have technical responsibility for designing and developing new modules/content for the product, reviewing and approving documentation. I will also provide technical guidance to the engineering team and work closely with the System Design Authority to develop and support MIMESIS for our customers. This is a unique opportunity to join a growing team of approximately 30 systems and software engineers, shaping the next generation of maritime simulation through emerging technologies. At BAE Systems, I will be part of an inclusive culture that values diversity of thought and rewards integrity and merit. I will have the opportunity to fulfil my potential, and reasonable adjustments will be considered for candidates with disabilities or health conditions.
