"The group is entering into discussions with employees and their representatives with a view to improving productivity by reducing by up to 2300, the number of managerial, professional and clerical staff working in the business," Rolls-Royce said in a statement.
It added: "These actions will also help the group to mitigate external headwinds such as increasing raw material costs and the weak US dollar."
The company takes a major hit from the falling US currency because its engines are priced in dollars.
Rolls-Royce gave no exact breakdown of the job losses, but said it would aim to shed jobs through voluntary redundancy.
Global impact"The impact of these proposed changes will extend to the UK, US, Germany, the Nordics and other countries where the relevant functions are located," Rolls-Royce added.
"In the UK, the group will seek to secure the headcount reductions, wherever possible, through voluntary redundancy."
Rolls-Royce manufactures engines for the civil and defence aerospace, marine and energy sectors.
The firm employed 39 500 people in 50 countries at the end of November last year, including 23 300 workers in Britain, 8 300 in North America, 2 300 in Germany, 3 400 in Scandinavia and about 680 in Asia.
"We are determined to create a leaner and more agile support structure, better suited to the global markets in which we operate," said group chief operating officer Mike Terrett in the statement.
"The investments we have already made in new management systems will help us deliver this simplified organisation.
"Rolls-Royce will continue to focus on ongoing cost reduction and productivity improvements as the business grows."
The restructuring would have no impact on the group's financial performance in 2007, the group said. Instead, costs would be balanced by savings achieved over 2008.
