Britain's biggest defence company, headquartered in London, with more than 50 UK sites. Its Digital Intelligence business works on cyber and intelligence, and it runs graduate, apprenticeship and placement routes.
BAE Systems is a British aerospace, defence and security company, and one of the biggest employers in UK engineering. It builds fighter jets such as the Eurofighter Typhoon and parts of the F-35, and warships and submarines, and it also works in cyber, digital and space. Many of its jobs are about protecting people and the systems a country relies on, so the work can feel very real.
BAE Systems was formed on 30 November 1999, when British Aerospace bought Marconi Electronic Systems and merged with it. Its headquarters is in London. BAE's UK careers pages describe more than 50 UK sites and a UK team of more than 35,000 people. Its cyber and data business has its own history. Digital Intelligence is headquartered in Guildford, Surrey, and began in 1971 as a small firm called Smith Associates doing defence research for the UK Government. It was renamed Detica in 2001, bought by BAE in 2008, renamed BAE Systems Applied Intelligence in 2014, and in 2022 BAE combined its digital, data and cyber units into the Digital Intelligence business.
We did not find a formal mission statement on the sources we read. The company's jobs site uses the line "Where purpose connects", but that is a recruitment slogan rather than a mission, so we have not treated it as one.
Digital Intelligence works in four areas: cyber security, data and digital solutions, space systems and battlespace integration (linking up the information that military forces use). Products named on Wikipedia include Azalea, DataRetain, DataBridge, Cross Domain and IntelligenceReveal. Cyber work sits alongside the better-known aircraft, ships and submarines.
For young people there are several routes. BAE's technology graduate pages (as at autumn 2026) list roles such as Software Engineer, Systems Engineer, Network Engineer, Data Engineer and Data Analyst for a September 2027 start. They ask for at least a 2:2 degree, the scheme is non-rotational and lasts 18 to 30 months, and the starting salary shown is £34,000 plus a £2,000 welcome payment. Its National Security Cyber Accelerator is a 12-month programme in Gloucester, Manchester or London with training from C++ to cryptography; it asks for aptitude in at least one programming language rather than particular qualifications, and applications were closed when we looked. There are also apprenticeships, including degree apprenticeships, and apprenticeship and early-careers open events run from 3 November to 11 December 2026. All applicants need at least Baseline security clearance, and many roles need higher vetting, which typically needs 5 to 10 years of continuous UK residency. Nationality, previous nationalities and place of birth can limit which roles you can do.
