Professional services firm KPMG is to create 800 new jobs in 2020.
The positions will be based across its offices in Dublin, Cork, Galway and Belfast.
It says increased client needs in all areas - including access to technology and digital related expertise - were among the drivers of growth.
Some 400 of the positions will be filled by experienced professionals with a wide range of skills, the company says.
A further 400 graduate opportunities are available across all areas - including audit and assurance, tax consulting, deal advisory and consulting.
There are also additional opportunities in traditional parts of the business including tax consulting, corporate finance, transaction services and regulatory advisory.
Managing partner of KPMG in Ireland, Seamus Hand, said: "The challenges of rapid technological change and greater regulation are among the key drivers for success in Irish business and are reflected in the increased demand for our services and the roles we're looking to fill.
"Increased focus on technology including areas such as cybersecurity, digital and data analytics is resulting in strong growth in these services, as well as continued demand for our expertise in the audit, tax and advisory areas."
"As a result of the increased focus on climate change, we’re investing to build on our existing expertise and capabilities to help our clients assess and implement their own sustainability and decarbonisation strategies.
"This is good news for those seeking work in KPMG as we expand the range of career opportunities available to both graduates and experienced professionals," he added.
Commenting on KPMG's plans to hire 400 graduates, Mr Hand said: "Talented and ambitious graduates have more choice than ever before.
"We're basing our appeal to graduates on the opportunity to work with a diverse range of clients, across a wide spectrum of disciplines spanning technology and digital transformation, international tax and deal advisory to name just some of the opportunities."
KPMG employs over 3,400 people in Ireland, which saw revenues for 2018 at €414m.
