Ocado technology have launched an aggressive recruitment drive to target the City‘s best technology employees.

Workers in the technology divisions of companies such as UBS, Skype and Amazon arrived at work this morning to see a series of targeted clean job advertisements on the doorsteps of their offices, inviting them to apply for a position at Ocado Technology.

Applied overnight using a high powered water jet and a series of stencils, the “clean” job adverts feature comments such as “Fed up of being a drone? Try programming one instead” and “Allowed to pitch ideas to your CEO? Then implement code in 2 hours? Thought not.”

The firm, who announced the appointment of retail veteran Sir Stuart Rose in January this year, has yet to post a profit since its foundation in 2002, but says it will ‘make hundreds of millions of pounds‘ in the future.
