A US internet company is to create 100 jobs in Dublin, doubling its workforce by the end of the year.

The positions will be in the customer experience and hospitality teams at property rental website Airbnb’s Dublin office.

Airbnb announced last September that it was establishing its European HQ in Ringsend, with the promise of around 100 jobs.

However, the firm now plans to double its workforce by the end of the year.

It also officially opened its new offices in Dublin today.

Established in California seven years ago, Airbnb is a website which enables people to rent out part or all of their property while they are away or at home.

The investment is supported by the Department of Jobs through the IDA, both of whom have welcomed the announcement.

Airbnb is reportedly in the process of raising up to $500m (€365m) to expand its business, a move which would value it at $10bn.

Elsewhere, 27 new high-tech jobs are to be created at a research and development centre in Co Cork.

The Nimbus Centre for Embedded Systems Research at the Cork Institute of Technology plans to fill the positions this year.

Recruitment has already begun.

The roles are all related to the centre's research into the "Internet of Things", energy and water management technologies.
