Hi there,
I work as a service engineer for a company called Mantis Deposition, I travel around the world installing and repairing scientific systems for universities and research facilities. We are trying to recruit another person to help, but it's proving to be a very hard role to fill, so I thought I would ask in here.
Have a look at the field engineer role in the link and if you or anyone you know may be interested, send your cv on. It is a great place to work for and its a great way to see the world without having to pay. Let me know if you have any questions.
