Chicago-based, Citadel Securities is the largest trader of equity and derivative equity products in the US.
It established an operation in Dublin’s Docklands earlier this year, currently employing about 15 traders, analysts and programmers.
The firm’s Global Head of fixed income, currencies and commodities, Paul Hamill has said that Citadel plans to treble that workforce with two years, according to The Irish Times.
He added that its decision to come and grow here preceded Brexit and was based on the talent available here and on the city’s strong business environment.
"The strength of the Dublin environment creates competitive forces, where you get good people and growing businesses," he told the newspaper.
"We need to wait and see. There’s simply not enough information at this stage" he added, commenting on the potential impact that Brexit will have on its Irish operation.
The company has signed a 15-years lease on the top floor of 1 Grand Canal Square at Grand Canal Dock in Dublin.
