Mark Little is to step down as head of Twitter in Ireland just months after assuming the role.
The unexpected move comes as a result of an ongoing company-wide restructuring effort in Twitter as it seeks to turn a profit and grow its user base.
Little is a former RTE television anchor and founder of Storyful.
No replacement has been announced for the role.
“For several months, Twitter has been considering changes to its media partnerships team, which I led in Europe,” said Little today.
“In October, the decision was made to restructure the team and locate its leadership roles in the United States. I was asked to consider a possible return to the US, where I was living when I joined Twitter, or building on my role as Twitter’s managing director in Dublin. I decided that neither would be the right fit for me - or Twitter Dublin - and opted for a mutually agreed exit from the company.”
A spokesman for Twitter added: “Mark Little will step down in his dual role as MD of Twitter Dublin and vice president of media in Europe. We want to express our gratitude for his exemplary stewardship of Twitter Dublin and for leading our European media team over the past 12 months.
"From building his own company, to reporting on world events across the globe, Mark brought his wealth of professional experience to bear on our media partnerships efforts across the continent. We wish him all the best for the future.”
Twitter recently announced its intention to lay off 9pc of its workforce around the world, or roughly 350 people.
It is unclear how many Irish staff will be let go. Twitter employs over 200 people at its Dublin-based international headquarters.
“We announced a restructuring and reduction in force affecting approximately 9pc of Twitter’s positions globally,” said the company in its most recently quarterly earnings statement. “The restructuring, which focuses primarily on reorganising our sales, partnerships and marketing efforts, is intended to create greater efficiency as we move toward our goal of driving toward profitability in 2017.”
Twitter has endured a difficult period over the last 18 months with modest user growth compared to rivals such as Facebook and Snapchat.
The company recently had to abandon a sales process with potential bidders such as Google and Salesforce walking away from an acquisition of the social network.
“The restructuring allows us to continue to fully fund our highest priorities, while eliminating investment in non-core areas and driving greater efficiency. Over time, we will look to invest in additional areas, as justified by expected returns and business results. We expect to recognise most of the pre-tax workforce restructuring charges in Q4.”
Twitter has announced that Chief Operating Officer Adam Bain, widely credited with building a robust advertising business at the company even as it struggled with user growth, is leaving to explore other opportunities.
