"They have a well balanced squad and I am looking forward to getting stuck into preparing them for the World T20 in our training camp in Colombo.
"I see this as another opportunity for me to work with another international team and to further my coaching career."
Cricket Ireland performance director David Holdsworth revealed the International Cricket Council had helped finance the move.
"Craig's enthusiasm, experience and knowledge will add further strength to our coach support staff and we thank the ICC high-performance programme for their financial support towards achieving this," said Holdsworth.

McDermott's son Alister won a first call-up for Australia's current tour of the United Arab Emirates.
