They're big players in the IT and digital communications business around the world: designing, building and managing big computer systems that run many of the things we do in our day-to-day lives, such as transferring money electronically around the corner, and around the world.
They're behind the IT system that runs the UK's Crown Prosecution Service, and much of the background hardware and software that enables us to send texts.
At the end of last year, Logica employed 21,000 people across 34 countries, and turned over £1.66bn, making a profit of nearly £70m. More than 6,000 people work for Logica in the UK.
The headquarters are in North London, between Euston Station and Regent's Park, but at any one time, 50 per cent of UK staff are spread around the company's regional bases, from Staines to Glasgow, and in clients' offices.
Is this you?
Up to 200 recruits are taken on every year, including those on mid-course work placements. For graduate jobs, most will have at least a 2-2 in a computer science or other degree with a heavy numeracy and logic content, and a strong flair for IT generally.
The recruitment process:
All applications start online, at www.logicacmg.com/ukgraduates and, for next year, open in November. Your application is screened for evidence of some commercial work experience, team working and communications skills, and determination, maybe as a result of recovering from a setback somewhere in your life.
These areas may be explored more thoroughly in a visit to an assessment centre, which sounds like a full day, as it includes an interview, a group exercise, a written exercise and two aptitude tests.
If you're picked, you're invited back to the office to meet staff and learn more about the company before deciding whether you want to join. Graduate training lasts 12 months, but you'll start by working on a real project, rather then spend weeks in a classroom.
Salaries for 2006 haven't been set yet, but this year the range was £17,500 to £21,750, depending on location.
Beam me up Scotty?
There are numerous examples of graduate recruits who've gone on to fill senior managerial and technical roles within the company. Mobility is essential, with clients based all around the UK, and many graduates will work away, sometimes for weeks or months at a time.
Who's the boss?
Dr Martin Read became the group chief executive in 2002. His CV, since he graduated in natural sciences at Cambridge in 1971, is dotted with household names, including GEC, Marconi, Courtaulds and P&O.
Little known fact:
Logica process two out of every three text messages sent in the world, which, as we know, corresponds to a large amount of thumb movement.
