Jobs advertised in the IT&T sector rose 2.86% in May with software development, desktop support and sales leading the way, according to the latest Olivier Job Index.
Multimedia, Internet and Graphics were also big winners rising 5.21%, perhaps as a legacy of the growth around Web 2.0, according to Group Director Robert Olivier.
Olivier said that companies were increasingly looking to recruit permanent staff.
"The skills shortage means that they need to corral people and keep them on the team as long as possible. Once they wanted to hire contractors because they could drop them if the market turned. But no-one's scared of a business downturn at the moment - the contraction of their labour forces is the last thing on their mind," Olivier said in a release.
Over the last year the IT&T job ad numbers have risen almost 40%.
