Up to a thousand new jobs are being created in County Galway.
Dexcom is building its global manufacturing facility in Athenry - the high-skilled roles are coming on stream over the next 5 years.
It'll provide about 500 construction jobs while it's being built and up to 1,000 high tech graduate and technician positions.
Executive Vice President of Global Operations at Dexcom, Barry Regan says it's a great location for the company:
"With the continued success of our Dexcom G7 in Europe, we're pursuing an ambitious growth strategy that requires increased manufacturing capacity to support a rapidly expanding European user-base."
"Ireland has an exceptional talent pool and an established med-tech sector, making Athenry the perfect location for us to establish a new, state of the art manufacturing facility."
