Principal Product Security Engineer

General Dynamics Mission Systems engineers a diverse portfolio of high technology solutions, products and services that enable customers to successfully execute missions across all domains of operation. With a global team of more than 13,000 top professionals, we partner with the best in industry to expand the bounds of innovation in the defence and scientific arenas. In the UK, we are leading the way in avionics and communication systems. Given the nature of our work and who we are, we value trust, honesty, alignment and transparency.

General Dynamics in St Leonards-on-Sea currently provide avionic mission computing systems for a wide range of military fast jets, helicopters, and UAVs. Recent success has resulted in General Dynamics developing the next generation of Advanced High Performance, Safety Critical Mission Computer Systems to meet the needs of latest platforms in development by several aircraft manufacturers. These Mission Computing Systems provide the functionality that integrates aircraft systems, sensor systems and stores management systems with the information and control systems required by the aircrew to meet the demanding operational needs of these aircraft.
