BAE Systems Digital Intelligence is home to 4,500 digital, cyber and intelligence experts. We work collaboratively across 10 countries to collect, connect and understand complex data, so that governments, nation states, armed forces and commercial businesses can unlock digital advantage in the most demanding environments.

WHAT YOU’LL BE DOING

BAE Systems have been contracted to provide Security Operations services to support the cyber defence of a number of UK CNI organisations. BAE Systems provides these services through either the stand up and delivery of a dedicated security operations centre to the that organisation, or through the integration of our own staff, team and expertise into the organisations existing Security Operations capabilities and teams.
The networks we protect may be a combination of on-premises and/or Azure and AWS cloud hosted platforms, in some cases with many hundred systems within these environments that must be protected. In addition there may be scope for the monitoring non-enterprise IT environments, such as safety critical operational technology systems.
The SOCs may be staffed by a blend of customer and BAE Systems staff, based in multiple locations, but day to day operations will be mixed between delivery from our offices, with working from customer site locations within the UK. Whilst there may be the opportunity for hybrid working for this role – typically up to 2-3 days per week from home, some face-to-face on site working is essential to this role.
The SOC Analyst roles are ‘hands-on’ shift-based roles, working as part of a 24/7 operation with four shift teams working in a standard rotation.
