A financial services firm has announced plans to take on 200 new staff in Galway and Dublin.
Fidelity Investments is to hire workers to fill roles in technology, back office operations and enterprise services over the next few years, the IDA said.
Minister for Jobs Richard Bruton said the development was further good news for the financial services sector in Ireland.
“Government will continue to work hard on implementing the necessary changes to ensure that we can see further announcements like this,” he said.
Fidelity Investments had managed assets of $1.7 trillion at the end of September.
"Ireland is a proven market in which Fidelity can continue to develop a vital part of our increasingly global
organisation," said Travis Carpico, president of Fidelity Investments Ireland.
The investment is supported by the Department of Jobs, Enterprise and Innovation through IDA Ireland.
Meanwhile, gaming company Swrve has announced plans to add 100 jobs to its workforce over the next two years.
The firm, one of the world's leading mobile gaming businesses, will create the jobs on the back of funding worth
$6.25 million (€4.92 million) led by Atlantic Bridge Partners and Intel Capital.
Swrve is already used by some of the world's largest games publishers — handling the data of more than five
million players every day.
Swrve chief executive Hugh Reynolds said: "This funding round puts us in an outstanding position for growth".
"Our team in Dublin already consists of the brightest and best — we just need more of them. A lot more."
