The cuts will come across sales, technology, engineering and support functions.
Google is to cut 240 jobs from its Irish-based workforce as part of global layoffs announced last month.
Staff were informed by email today and a collective consultation process will begin tomorrow.
Some 85 of the layoffs will be in sales, 80 jobs will go in technology and engineering, and the remaining 75 job cuts will impact support functions.
The 240 job losses represent around 4% of Google's 5,500 Irish-based headcount.
Last month, Google's parent Alphabet announced plans to cut around 12,000 jobs, or 6% of its global workforce.
