Microchip maker Advanced Micro Devices is to create up to 290 new jobs in Ireland over the next four years.
AMD will invest up to US$135 million (€123m) to fund several strategic R&D projects in Cork and Dublin.
The company says as well as the new jobs, there will be a "broad range of additional support roles."
Its chips are used in everything from Tesla cars to NASA's Mars Rover.
It first established Irish operations in 1994 with the first purpose-built site outside of the US, and began operations a year later.
There is a focus on manufacturing, operations support, engineering and administration services.
AMD says Ireland is now home to one of its largest R&D sites in Europe.
Ruth Cotter, senior vice president of marketing at AMD, told Newstalk Business Editor Joe Lynam there is a 'tight spot' in relation to housing workers.
"The technological infrastructure, we've obviously been partnering with the Government and others, the instructure has been very, very strong," she said.
"There is a bit of a tight spot at the moment as it relates to housing availability for several of the target groups we would have, in terms of new college graduates and even more experienced engineers and support professionals that we're trying to attract to the company.
"We believe the plans have been put in place to resolve that, and everybody's collectively working through that here over the next several years.
"We're looking forward to that being resolved over time, but certainly there is a pinch period at the moment".
Ms Cotter said its Irish operations cover several different areas.
"Our R&D teams in Ireland will design innovative high-performance and adaptive computing engines to accelerate data centre, networking, 6G communications and embedded solutions while taking a leadership position on artificial intelligence," she said.
"For nearly three decades, Ireland has been a flagship European R&D centre developing adaptive computing solutions, drawing from a strong and highly-skilled workforce.
"By further investing and expanding our presence in Dublin and Cork, we are committed to continuing to both drive innovation in Ireland and to support the European semiconductor ecosystem," she added.
