Born in Caldes de Montbui, Barcelona, Catalonia, Walter finished his formation at FC Barcelona. He started his senior career in the lower leagues, being successively loaned to CF Sporting Mahonés and Antequera CF.
For 2009–10, Walter signed for four years with Segunda División club Gimnàstic de Tarragona, making his professional debut on 30 August 2009 by starting in a 1–0 away win against Real Murcia and finishing the season with 34 matches (21 starts). In late June 2011, however, both parties agreed to cancel his contract, and he was loaned to Hungarian side Videoton FC for two years.
Walter played his first match in top flight football on 24 July 2011, featuring the full 90 minutes in a 4–0 home success over Paksi SE. He had first appeared in the UEFA Europa League 11 days earlier, coming on as a second-half substitute in a 0–2 loss at SK Sturm Graz.
