The Reading-based staffing agency says it has been "inundated" with requests for legacy programmers, and attributes the demand to pressure on established multinationals and blue-chip companies to integrate their on-line systems with huge volumes of data held in their existing mainframe systems.
Consequently, legacy programmers, who understand the workings of a mainframe system, are being called in to manage the transfer of data to servers.
"Although in the past we have seen less of a requirement for the more mature employee, the 'e-legacy' movement is changing this trend," comments Chris Bartlett, co-founder of GCS.
"It's an older boys' game now and those with the legacy skills are expected to become highly sought-after individuals over the next few years. It also means that they can start to learn the newer skills needed in the industry - proof that you really can teach an old dog new tricks."
According to David Bloxham, operations manager at the agency, contract staff are most likely to benefit from this movement, as 'e-legacy' work is predominantly project based. He lists Cobol and Powerhouse on IBM, ICL or digital mainframes as the most frequently requested legacy skills, but adds that internet technologies such as Java are an added bonus.
