Tánaiste Mary Coughlan said the investment would increase the reputation of the Swords base as a centre of excellence.
“A high-value transformation of this nature is characteristic of the Government’s ‘smart economy’ strategy and I look forward to working closely with Hertz as it continues to develop and expand its presence in Ireland,” she said.
The expansion will take the Hertz workforce in Swords to 930.
The jobs will be based at the Hertz European shared services centre offering back-room support for the company’s human resources, finance, sales and customer care teams.
Staff will also offer customer reservations and other support services for clients in Europe, the Middle East and Africa.
The investment was supported by the Government through IDA Ireland.
