French firm Teleperformance says it is recruiting customer service advisers, trainers and team managers for call centres in Glasgow, Airdrie, Erskine and Kilmarnock.
The recruitment will take the company's Scottish workforce to more than 4,000.
Teleperformance provides customer care, technical support, call centre, debt collection and social media services to clients such as Traveline Scotland and the Students Loans Company.
First Minister Alex Salmond said: "This is a welcome boost for employment and further strengthens Scotland's position in outperforming the UK for securing inward investment."
Alistair Niederer, chief executive of Teleperformance UK, Ireland and South Africa, said: "The current growth plans for Teleperformance in Scotland reflect a confidence in the future, not just for Teleperformance but for the clients we serve.
"This reflects the level of growth and confidence we are seeing in our business across the UK."
