An engineering business called Camlin is creating 298 jobs as part of a £28 million expansion at its Lisburn-based headquarters.
The company develops and supplies engineering solutions, predominantly for electricity and rail industries.
Invest Northern Ireland have offered £5 million to support the company and local engineering.
"The 298 new jobs, 98 of which are already in place, will generate over £9.5 million annually in salaries to the local economy," said Mr Hamilton.
The Camlin operation spans over 21 countries across the globe and currently employs 251 people at its Lisburn site.
John Cunningham, the company's chief executive, said: "This major investment is part of an ambitious and strategic growth plan designed to help us increase our global sales and market presence.
"This new building is giving us the scope to accommodate an increased workforce and fully implement our growth plans."
