Tata Consultancy Services, the global IT, digital and business solutions company, is to expand its presence in Co Donegal, adding 200 new jobs.
The new roles will be across a range of specialties and will be filled over the coming months.
The company, which is part of the Indian industrial conglomerate Tata Group, already employs over 1,000 staff in Letterkenny.
"We are creating high-value employment opportunities across a variety of roles and disciplines, including cybersecurity, cloud services, project management, data analytics, customer service and IT helpdesk," said Andrea McBride, head of the TCS Global Delivery Centre in Letterkenny.
The business, which employs 592,195 staff made up of 153 nationalities across 46 countries, will be recruiting people at all stages of their careers, from graduates through to experienced professionals.
The company is holding a careers open evening in its office in Letterkenny on July 14th.
TCS first opened an office in Dublin in 2001 and added a Supply Chain Centre of Excellence here in 2012.
In 2015 it announced it was adding 80 more staff.
Five years later, it bought Pramerica Systems Ireland, a subsidiary of US based Prudential Financial Inc.
At the time Pramerica employed 1,500 people.
