Amazon  will add more than 1,000 new jobs in Ireland over the next two years, the US online retail giant said on Monday, taking its workforce to more than 3,500 in a country that continues to be a magnet for major technology firms.

The move was the largest by a multinational company in Ireland this year and adds to the 11,300 announced by foreign companies in the first half of the year, a slight increase on the same period a year ago, according to Ireland's investment agency, IDA Ireland.

Ireland has a decades-old policy of attracting multinational jobs with a corporate tax rate of just 12.5 per cent, making it a hub for US companies - including heavyweights such as Apple, Google and Facebook - which account for one in 10 local jobs.

Amazon said the new Dublin-based roles will include software engineers, security specialists and big data specialists at both Amazon and Amazon Web Services, its cloud unit.

The Seattle-based announced earlier this month that it would add 2,500 jobs in neighbouring Britain, boosting its presence there to nearly 28,000.

"Amazon's decision to bring another 1,000 jobs to Ireland underpins our mission to make this country an innovative, digital economy and a global leader for the tech sector," Irish Prime Minister Leo Varadkar said in a statement.
