A US cyber security firm is to create 400 jobs as it dramatically expands its operations here.
Symantec said it will hire 200 staff in Dublin this year and the same number again by 2015.
The jobs are being created as the company sets up a "European Customer Management Centre" at its offices in Blanchardstown.
The company is looking for employees with varying skill levels, but many will require at least one foreign language. Staff will also need a mixture of technical and IT skills. Around 32 languages are spoken in the Dublin office as it is.
The expansion will bring to 1,000 the number of people Symantec employs in Dublin.
One of the biggest IT security firms on the planet, Symantec set up offices in Dublin in 1991. The $16bn (€12bn) company has since expanded steadily to become one of the biggest employers in west Dublin.
It uses the site for a security operations centre, as well as for software development and testing.
Taoiseach Enda Kenny hailed the "significant" announcement by Symantec.
"Symantec's establishment is a signal of its continuing commitment to Ireland and contribution to our economic recovery. It is also a testament to our talented and flexible workforce," he said, adding that the Government was "committed to working" with companies like Symantec to bring more jobs here.
Symantec's senior vice president for its operations in Europe, the Middle East and Africa, Matthew Ellard meanwhile said his firm was "eager" to enhance the business's place in Ireland.
"These new jobs offer the opportunity for talented and driven individuals to join a high-performing company . . . and enhance their career.
