|Amec, which works closely with the UK's Nuclear Decommissioning Authority, currently employs around 400 people at its Darlington facility - although it also has bases in Brazil, China, the United Arab Emirates and the US.
Speaking about the new employment prospects in the North East, Darlington MP Jenny Chapman said: "I've always been proud to have Amec in Darlington and their presence, coupled with this job creation, are a real feather in the cap.
"To be creating 700 jobs is tremendous and it's a real boost to the local economy, adding to the confidence already generated by the firm having its head office here. It just proves Darlington and the region are good places to do business."
The news of the recruitment drive comes as Amec looks to increase its expansion efforts. According to telegraph.co.uk, the firm agreed a £2 billion deal to acquire US-based rival Foster Wheeler earlier this week.
