IT and communications service provider Paradyn is set to double its workforce from 40 to 80 employees by 2020, with positions in both its Dublin and Cork offices.
The new jobs are being created as part of a €4m investment that will fund company growth and acquisitions.
The new roles will mainly be in the areas of finance, network engineering, technical solutions architecture, technical sales and support, marketing and business development.
Paradyn was formed after the recent merger of Exigent Networks, Irish Telecom and Netforce.
It manages more than 30,000 users across 300 business and public sector customers from a range of industries.
The company's current turnover is €8m and it said it wants to double this to €16m in the next three years.
It also said it was looking to acquire "complementary businesses" in the Irish market.
