Max started his career at Queens Park Rangers and his six years with the club included loan periods with Yeovil Town, Preston North End, Stevenage, Carlisle United and Gillingham. 

After playing 27 times in the league and scoring once during his time at Priestfield in 2014-15, the German signed for the Gills permanently in July 2015, signing a three-year contract, and went on to captain the club.

 The defender opted to join Bristol Rovers on a two-year deal in July 2020, but the contract was terminated in June 2021 and he returned for a second spell at Priestfield on the same day.

In 2023 that deal was extended by a further two seasons and, on the final day of the 2023-24 season, racked  up an impressive 400th appearance for the club. Only six other players in the history of the club have achieved the same feat.
