Hanley Energy has announced plans to create 150 new jobs, split between the US and Ireland, as part of its global expansion.
It says 100 of the jobs will be created in the US this year, with the remainder in Ireland.
The Co Meath firm made the jobs announcement as it opened its $12m US headquarters in Ashburn, Virginia.
Hanley Energy specialises in critical power and energy management solutions and has operations in 32 countries.
Its clients include major cloud and data centre companies, including Amazon Web Services, as well as Largo Foods and CIE.
"Opening our North American headquarters and expanding our global workforce... is a pivotal milestone in Hanley Energy's global operations as we grow our global workforce to over 950 employees," said Clive Gilmore, CEO of Hanley Energy. "It also lays the foundation for future expansion as we deliver energy and power management solutions to our partners Amazon Web Services and other multinational technology providers in the U.S. and across the world."
Hanley Energy is one of a number of Enterprise Ireland-backed firms to announce further investment in the US this week.
"Ireland plays a vital role in supporting the global construction industry, designing, and delivering advanced infrastructure across the data, pharma, and energy sectors and improving resource efficiencies across the lifecycle," said Enterprise Ireland CEO Leo Clancy. "As a country, we have developed incredible capability in this area, and we are exporting this expertise across the world.
"Hanley Energy are at the heart of this, and their energy tracking software plays a vital role, helping industrial customers be more sustainable and efficient."
Enterprise Ireland is holding a number of overseas events this week to highlight the work of its clients.
Today it is hosting a sustainability event in Washington DC, at which the US special presidential envoy for climate, John Kerry, is a keynote speaker.
Speaking in Washington ahead of this year's St Patrick's Day celebrations, Taoiseach Leo Varadkar said Hanley's work "helping large industries to reduce emissions has never been more timely.
"Climate change is the greatest threat facing humanity today," he said. "I believe Irish businesses, and enterprise in general have a pivotal role to play in turning the tide on climate change and biodiversity loss so we can leave the planet to the next generation in a better condition than we inherited."
Neil Morris, Amazon Web Services (AWS) Country Lead, Ireland said; "Seeing Hanley's rapid expansion over the last few years is another reminder of the hugely positive effects that international investment is having on Enterprise Ireland clients in Ireland. Launching a US Headquarters is a significant moment for Hanley and I wish them continued success."
