How do people get into jobs that they travel with?

[Pig benis]

Hello all

Currently I work in IT, and have done for the past 4 years. I enjoy it very much and have done a fair few qualifications (CCNA, OSX certified to name a few).

The part I love about my job is being called out onsite to resolve a fault. Currently I work 2nd/3rd line and I would like to progress into a 3rd support job, but one with a lot more travelling whether that be in the UK, or outside.

Here is my question, where do people find these jobs that take them abroad, or just around the UK?

Thanks
P.B
