text: 1 Race engineer 
  A race engineer liaises between the driver and the mechanics. 
  Typical salary: New graduates start at £25,000 to £30,000 and quickly progress to junior engineer roles, earning more than £40,000 with just a few years’ experience. Senior race engineers earn £50,000 to £90,000 and promotion often leads to six-figure salaries. 
  What the job involves: “A race engineer acts as the interpreter between the race-car mechanics and the driver,” says race engineer Jamie Muir. “The engineer takes feedback from the driver, analyses the data available and makes decisions about the set-up needed for maximum performance, then relays this to the mechanics to instigate.” 
  Qualifications: A university degree, typically in automotive/mechanical engineering or motorsport technology. Hands-on experience is essential. 
  To succeed as a race engineer, you need … to be able to deal with pressure. 
  Worst thing about the job: The long hours. “Race engineers work 24/7,” says Chris Aylett, CEO of the Motorsport Industry Association. 
  2 Ethical hacker 
  Typical salary: £60,000 to £90,000 at team- leader level, while a newly qualified hacker can expect a minimum salary of £35,000 to £50,000. 
  What the job involves: A company will pay an ethical hacker to hack into its computer system to see how well it might stand up to a real attack. 
  Qualifications: You don’t necessarily need a degree in computer science. The industry accepts individuals with a very wide range of academic qualifications and skills. 
  To succeed as an ethical hacker, you need … a passion for technology and detail. You should also have a very good analytical mind and enjoy solving difficult problems. 
  Worst thing about the job: When you are called in to test the security of a new customer’s network only to discover that they have already been the victim of a data breach. 
  3 Bomb-disposal diver 
  Typical salary: In the private sector, you can earn up to £100,000 working just two months out of every three. 
  What the job involves: Descending to the sea bed and searching for unexploded ordnance (bombs, shells, grenades and landmines), then either safely recovering and collecting the weapons or securely disposing of them.

  To succeed as a bomb-disposal diver, you need … to stay calm in stressful situations. You work on your own at depth, with nil visibility and, if you don’t like living in small confined spaces with lots of other people, forget it. 
  Worst thing about the job: Expect to be away from home at least six months of the year. 
  4 Social engineer

  The job: A social engineer is paid by a company to try to trick its employees into divulging confidential information that allows the engineer to access sensitive company data or the company’s computer network. 
  Qualifications: Typically, social engineers have a degree in IT, although an understanding of psychology is useful, as is a background in marketing, teaching and customer service. 
  To succeed as a social engineer, you need … the confidence to lie convincingly and the ability to fit in almost anywhere without looking too out of place. You also need a strong sense of personal ethics and an understanding of the law.
