The company said the jobs will be rolled out as it helps banks and other businesses prepare for the change to the Single Euro Payments Area (SEPA) on 1 February 2014, which will provide a common payment processing system across the EU.
Sentenial said 30 of the jobs will be advertised before Christmas with the remaining 80 to be filled by the end of 2014.
Chief executive and founder Sean Fitzgerald said the jobs announcement was a positive step by the 1o-yea-old company.
“I am very proud to have built a successful indigenous Irish technology business from a start-up in 2003 into a rapidly growing business at the heart of the European payments system,” he said.
Sentenial currently employs 160 people. Its banking customers include AIB, Bank of Ireland, Bank of America and ING.
