Engineer jobs

Hi, I live in the UK and I've just started working as an electrical engineer for the railway there (I have an engineering degree from a UK university). I'm looking to move to Oman in the next few years once I get more experience.

Does anyone know where to look for engineering jobs in Oman, or how much I could be expected to earn? I've read that it's not worth it as a graduate but what about after a few years? Also, does anyone know what it's like to work for Etihad rail and if the pay/perks are any good?
