Northern Ireland medical firm The Almac Group said it has created more than 300 jobs in Northern Ireland in the last 12 months and an additional 414 employees across its operations in the UK and in the US.
Almac in Craigavon, which was founded by former pharmacist Sir Allen McClay, is in the process of transferring operations into its new $120m (£76m) US headquarters in Pennsylvania and said it was recruiting 100 additional employees in the UK.
The new jobs have been created in research and pharmaceutical development.
Almac chief executive Alan Armstrong said he was confident that 2011 would see further expansion of employee numbers as Almac continued to expand its customer base and product range.
"In the 12 months between October 2009 and October 2010 we grew our employee numbers by 16% across our UK and American operations. We are still recruiting at the moment and we currently have 100 vacancies across the group. This week 23 new staff have gone through our induction process and typically we run an induction once every two weeks."
He said the growth of Almac in 2010 was a tribute to the legacy of Sir Allen McClay, who died in January.
