In the financial services sector, Gascoigne said that 70 percent of organisations in the sector have been forced to change their IT systems in light of new regulations within energy trading and risk management.

"Consequently, we're seeing an uplift in demand for IT professionals with experience of OpenLink, TriplePoint or SolArc," he said.

Meanwhile, the continued recovery of the asset management market means that there was an increase in demand for people with experience of Charles River and Fidessa LatentZero systems in March. Moreover, the return of bonuses in the investment banking sector is believed to be driving a growth in vacancies, with business analysts with CDO (collateralised debt obligation), CDS (credit default swap) or derivatives experience in particular demand.

Across all sectors, Gascoigne noted an efficiency drive that was boosting demand for Business Intelligence (BI) professionals.

"With many organisations seeking analysis on their spend and maximising existing infrastructure, we're seeing demand on the rise across the board for SAP BI roles," he said.
