Bishop previously worked at Costcutter from 2000 to 2002, and was the brains behind a bargain sponsorship of Michel Kratochvil, Tim Henman's opponent in the excruciating fourth-round battle during Wimbledon in 2002.
The game lasted far longer than anticipated, yielding many more views than expected for the £900 outlay.
Bishop has also held a managerial position at Booker.
He said: "Taking the position as marketing director for Costcutter will enable me to shape the strategy and development of what is a leading brand in the convenience sector.
"2011 represents both exciting and challenging times for the sector, and never before has brand cut-through been more significant. Already though, we are beginning to make momentous changes as our new brand strategy – Proud to be Local – is revealed this week via our new-look TV commercial.
"Our attractive and recognisable brand proposition, combined with the plethora of new and high-profile brand developments on the horizon, allow me every confidence that we can now really cement Costcutter's rightful position as the leading symbol group operator."
Jenny Holmes also joins the company as retail marketing manager, from Leeds-based agency Banana Kick, where she was responsible for the creation and delivery of marketing campaigns for key clients including Punch Pub Company and Welcome to Yorkshire.
