From the website:
We are currently recruiting and ask that prospective candidates have a minimum of 2500 hours total time - if coming from a commercial background this should also include at least 1500 hours commercial jet experience. You should also have either a UK ATPL or JAR licence, the right of abode in the UK and finally, you should be MCC qualified. Please note you must have access to a computer in order to receive company email notices and rosters.
If you meet these requirements, we would welcome an application from you. You can find our application form below. Please remember that we are interested in a wide variety of applicants and will continue to consider each CV on its individual merits. To make the most of the online application process, you need to fill in the form as fully as possible.
If suitable, your application will be added to our database. You will not need to update your details with us more than once a year (unless there are any major changes in your circumstances i.e. type conversion, command etc).
Please note that it is not necessary for you to call and confirm receipt of your application.
If you already have a current application with us you need not reapply - Your details will still be kept on our existing database and we will continue to look through this as and when interviews are set up.
Finally, thank you for applying and good luck!
My emphases.
