AOL Ireland has announced plans to create 40 new software engineering roles over the next 12 months at its Dublin Development Centre.
The company has been based in Dublin for 16 years and currently employs 170 people.
It said that potential candidates for the new jobs will need industry experience and will work with programming languages such as Java, Erlang and C++.
AOL's Aengus McClean said the new jobs will help the company expand its products in display advertising into "a comprehensive, world-class offering that extends across the whole digital ad ecosystem and will set a benchmark for others to follow".
IDA Ireland's Chief Executive Barry O'Leary said the AOL investment involves significant levels of innovation and will lead to the Dublin operation becoming a centre of excellence for a strategic growth segment for AOL.
"The research and development aspect of the investment will provide the basis for deeper engagement with research centres in Ireland and the successful completion of this project will result in the positioning of the Irish centre to drive the future direction of digital advertising at AOL," he added.
