Granite Digital will create 50 new jobs across its Dublin, Cork and Galway offices, as part of a €2.5m investment in its business.
The new jobs will bring the company's Irish workforce to over 100 people within the next three years.
Granite provides a wide range of digital solutions to businesses and has seen particularly strong growth in the fintech, healthcare, education and hospitality sectors.
Its clients include Enterprise Ireland, Dalata Hotel Group, UCC, UCD, University of Wolverhampton, Uniphar, St James Hospital, Bons Secours Health System, Dublin Bus, Davy, Fexco and Aon.
Conor Buckley, CEO of Granite Digital, said the company has a strong presence in Dublin, Cork and Galway, adding that it is "fantastic" to be able to create further quality employment opportunities in these regions.
"We have a highly ambitious growth strategy which we believe is achievable by bringing the right talent on board so we have the skills and capacity to capitalise on business opportunities," Mr Buckley added.
Noting that demand for customer-focused, engaging websites and applications has grown exponentially in recent years, Mr Buckley said that Granite experienced significant growth on the back of this.
