Norcross, 20, previously played in the NPL for Mickleover Sports and follows the arrivals of Bradley Fortnam-Tomlinson, Mason Holwell and Charlie Scanlon.
Manager Lee Attenborough said: “I’m really pleased to sign Will [Norcross]. Again a player who fits the mould - young and hungry.
“He has come in pre season having not really being given a chance to play at Mickleover last season and from what I’ve seen so far, I have nothing but positive things to say about him.
“He is a tidy and technically gifted player who’ll give us something we’re missing at the moment. He is just as excited to join as we are to have him as he knows that I’ll give him the platform to express himself and attempt to make things happen on the pitch.
“He has a top attitude and a very good work rate to go with his quality and he’ll settle right in at Dynamo.”
