Amazon.com is searching for office space in Dublin that could hold as many as 800 people, according to two people with knowledge of the matter.
A report from the Bloomberg financial news service said the e-commerce giant is looking for as much as 80,000 square feet of office space in the city.
Amazon declined to comment on the issue.
Last year, the company said it would bring another 500 jobs to Ireland, adding to its more than 1,400 workforce in Dublin.
Amazon's search may add to a squeeze in the Dublin office market, as companies including JPMorgan Chase & Co and Barclays Bank, expand in Dublin after the UK voted to leave the European Union.
While the office vacancy rate in Dublin stands at about 9%, the figure falls to less than 1% for top quality buildings in prime areas of the city, Savills said last week.
A number of older office buildings were demolished this year adding to the shortage, it added.
"Demand for office space across Dublin remains robust," Andrew Cunningham, Head of Offices at Savills said in the report.
"With Dublin city centre having become so built up over the past two decades, older properties are having to make way to allow for new development to take place," he added.
