Currie will oversee all digital work produced for Seven Squared clients including Waterstone's, RAC, the Lawn Tennis Association, Grant Thornton and Direct Line.
Part of his brief will also be to further champion Seven Squared's social media offering. He reports to Mike Burgess, director of digital.
At Bauer Currie worked on properties including mojo4music.com and kerrang.com, and he also worked on the team that won the best new launch from the AOP for Whatson.com.
Burgess said: "Will has been creating influential and market leading websites over two decades and we're really excited to welcome his vast experience and creative flair to our team.
"He brings a wealth of insight, knowledge and creative experience that will prove invaluable to us and our clients."
Seven Squared was established in 2007 following the acquisition of Square One Publishing by Seven Publishing Group.
