Davies, who runs his own consultancy, the Open Intelligence Agency, has been hired on a six-month, two-day-a-week freelance contract.
His brief is to evaluate digital thinking in the agency and look at new ways in which it can offer its clients channel-neutral planning.
The appointment is part of the agency's wider integration effort. Earlier in the year, DLKW absorbed DLKW Dialogue, the agency's digital, DM and sales promotion arm, into the main agency.
DLKW already employs 35 digital specialists, with whom Davies will work on a range of accounts with heavy digital requirements. These accounts include Halifax, the AA and Capital FM.
Davies previously worked at Wieden & Kennedy before joining Nike as its global consumer planning director in 2005. He left a year later to set up his consultancy.
