About Serco

Serco is one of the world’s largest providers of public services to Governments, employing over 50,000 people in over 20 countries. The services we provide are often of critical importance to the communities and nations we serve. Providing public services is one of the most satisfying and rewarding careers you can have. You have an ability to make a real positive difference to people’s lives and to the safety and security of your community and country. Serco operates in five sectors of public-service provision: Health, Transport, Justice & Immigration, Defence and Citizens Services. Sometimes we are supporting people at troubled times in their lives, be they unemployed, refugees fleeing persecution, or in prison. In other parts of our business we are running some of the most advanced train services in the world, delivering essential support to armed forces, keeping hospitals safe and running 24x7, and providing environmental services. Serco is a business where people and values matter. We have a strong public service ethos, and we employ people who want to make a positive difference to other people’s lives. We operate in North America, UK, Europe, Middle East, Hong Kong, Australia and New Zealand, and we encourage people to develop their careers moving both between different businesses and countries. And as a business which delivers “front-line” public services, employing tens of thousands of people, we are constantly developing and promoting people; our need for skilled leaders is insatiable, and few companies can offer as many opportunities for people to grow their careers. We are looking for people to join Serco who share our desire to make a positive difference, the confidence to work as part of a team, the insight to spot the opportunity to do things better, and, importantly, the ability to take the initiative and put great ideas into practice wherever they are needed.
