Technology company Capgemini is to create more than 700 jobs across the West Midlands region.
The firm, which provides business and IT services to Her Majesty's Revenue and Customs (HMRC), hopes to recruit 500 employees in Telford, Shropshire.
It is also looking to find 220 people to work in Aston, Birmingham.
The firm, which also provides consulting and outsourcing services, already employs more than 2,800 people at its offices in Telford.
Capgemini said it is looking for a wide spectrum of skilled and experienced technical staff to work on the ASPIRE contract.
ASPIRE is the business unit within the company which was set up to deliver services to HMRC - which collects more than £430bn every year.
The company is holding two recruitment fairs over the next few weeks.
One will take place at the Whitehouse Hotel in Wellington, Shropshire, on Wednesday, 7 December.
The other will be at the Expression Suites at the NEC in Birmingham on Thursday, 1 December. Both will be held between 1600 and 2000 GMT.
