200 jobs have been announced in Ireland by recruitment website Indeed and energy provider Energia.
100 of the positions are at Indeed's Dublin-based Europe, Middle East and Africa headquarters and will be filled over the next 12 months.
Established nine years ago in the US, Indeed.com now claims to be the world's most popular online job search service, with sites in more than 50 countries and 28 languages.
In March last year, it opened an office in Dublin, and since then it has taken on more than 100 employees here.
Recruitment at Indeed for positions in sales, client services, business development, marketing, finance and operations, has already begun.
David Rudick, vice president international at Indeed, said Ireland had proven itself the ideal location for a high-growth technology company.
The expansion has been supported by the Department of Jobs through the IDA.
The other 100 jobs are to be created by independent energy provider Energia within the next 12 months as part of its planned entry into the residential electricity and gas market.
Energia currently supplies energy to 65,000 business customers and now wants to roll out its products to residential customers.
Through its parent group Viridian, the company has invested €1.2bn in power plants in Ireland in recent years.
The news of the 200 jobs has been welcomed by both Tánaiste Eamon Gilmore and Minister for Jobs Richard Bruton.
