Four hundred new jobs are to be created in Dublin by a US-based finance and human resources software developer.
It is understood that recruitment for the roles with Workday, which span a range of areas, is to begin right away.
The new positions will mostly be in product and technology development, as well as sales, customer operations, and other functions.
This will increase its number of Irish employees for Workday by 30 per cent.
The investment is supported by the Government through IDA Ireland and has been welcomed by An Taoiseach Micheál Martin and An Tánaiste and Minister for Enterprise, Trade and Employment Leo Varadkar, as well as the Minister for Finance, Paschal Donohoe.
The creation of these 400 additional jobs underlines the company's commitment to Ireland and is a real boost at time when so many people are out of work,' Mr. Varadkar said.
In addition, Chano Fernandez, co-CEO of Workday, said about the news: 'Since setting up operations in Ireland in 2008, we've attracted some of the industry's best talent to help develop our innovative products.'
'Our Irish team has helped to shape our technology and ultimately supported the success of our customers around the world.'
He added: 'With this added support, we'll be able to continue this great progress by expanding our efforts in the region and fostering a great culture in our Dublin office.'
Chris Byrne, senior vice president, technology customer operations, Workday, added that there are 'really dynamic career opportunities' available as part of the new hiring round.
Workday first came to Ireland in 2008 when it purchased Irish technology firm, Cape Clear.
The company employs 1,300 people, including 800 engineers, at its European headquarters in Smithfield in Dublin, which it has operated since 2015.
Overall, Workday has more than 12,000 employees around the world and its products are used by over 40 million people.
