The creation of 150 jobs at a global online payments company boosts Ireland's reputation as the internet capital of Europe, the state development agency said.
PayPal has begun hiring for full-time and part-time positions in customer and merchant services at its base in Blanchardstown, Dublin.
Bosses said candidates must be fluent in English, and a second European language is desirable but not essential.
The company, which processes payments over the internet, had already expanded with a further 100 jobs last year.
Barry O'Leary, chief executive of IDA Ireland, said the latest announcement proved Ireland's continuing ability to attract high-calibre jobs.
"PayPal's investment represents a key endorsement from one of the world's leading online companies, and builds on Ireland's reputation as the internet capital of Europe," he said.
PayPal, which is owned by eBay, said it has more than 94 million active accounts in 190 countries around the world.
It already employs more than 1,100 people in Ireland.
