Around 260 jobs are set to be created in Co Tyrone by a multinational manufacturing company.
US corporation Terex is investing almost £22m (€26m) in its operations in Northern Ireland.
The New York Stock Exchange-listed company manufactures a range of materials processing equipment at factories in Omagh and Dungannon.
The Terex GB jobs in Tyrone will be created over the next four years with £2.6m of support from Invest Northern Ireland.
"This significant reinvestment in Northern Ireland marks an exciting chapter in Terex Corporation's 13-year history in Co Tyrone and will be a major step in our long-term growth plans," said Terex Materials Processing President Kieran Hegarty.
He added: "We expect our turnover to increase further over the coming years and we will need to expand our factory space and workforce to cope with projected demand.
"The assistance offered by Invest NI has been instrumental in our decision to expand here and this project will help to strengthen Northern Ireland's position as a centre of excellence for mobile crushing and screening, from design through to manufacture and to global sales.
"Our talented and committed workforce has already made a valued contribution to our success to date, and we are confident the local workforce will continue to help drive our company's growth in global markets."
Northern Ireland's enterprise minister Arlene Foster welcomed the jobs announcement.
"Terex GB is one of Northern Ireland's top engineering companies and this decision to expand is a boost for Northern Ireland's vibrant materials-handling sector," she said.
"It also acknowledges the value which the Terex Corporation places on the skilled and educated workforce available here.
"As well as providing skilled employment opportunities in the local area, there is also the potential that this investment will create further skilled jobs in the Terex manufacturing supply chain."
The investment will see the construction of new factory space and purchase of new equipment, as well as research and development activities to support growth plans.
