E+I Engineering is planning to expand its manufacturing facility in Donegal and add around 100 new jobs.
Founder and managing director Philip O'Doherty told the Sunday Independent that the company was also looking at potential acquisitions in the United States.
"We're certainly looking at opportunities in the USA over the next year to 18 months - acquisitions either of technology or of companies," he said.
"Depending on how large the cheque was, we could certainly do a medium-sized acquisition without any outside capital, but we'd have to look at outside capital if it was a larger acquisition."
The new hiring programme will include roles for engineers, sales staff and production operatives.
E+I Engineering is the largest electrical switchgear manufacturer in the UK & Ireland, with a highly experienced and qualified team of Chartered Engineers working across three manufacturing sites. It was founded in 1986 by managing director Philip O’Doherty.
