Trotsky,
With TWR/APR experience you'd probably be more suitable for Dubai. Not sure how busy Keflavik is but bear in mind that Dubai will have moved around 260,000 this year. If your interested send your CV to Eric Melvin, Manager Technical Services at :

If selected you'd probably be required to come for an assessment to determine whether you know what you're doing and if you are suitable to train to validation standard at Dubai.
Good luck.
