Sorry guys, haven't heard of this operation at all. The photos on the weblink are for a Caravan (SXS) owned and operated by Southern Cross Safaris (know the boss well). One of other the photos on your Skylink website is taken at Wilson Airport, and features a Bosky caravan, a Safarilink Caravan and the spinner of the East African Air Charters C406. In other words a scenic shot of three of the local 'big' players' equipment. Not for an operation called Skylink.
If you have been offered a genuine job, you will first need to have a Kenyan licence and work permit if you are flying a 5Y registered aircraft in this region. Neither are cheap or easy or quick to get.
There are a lot of operators based/licenced in Kenya but who operate contracts in south Sudan or Somalia. It could be one of these, but there's not much info or detail on the website. I'd find out a lot more about exactly who they are, what they are flying and where before making any financial committment.
