Born in Ludvika, Söderström started his professional career with lowly IK Brage. In January 1997 he moved to Vitória de Guimarães in Portugal, where his stellar performances attracted the attention of fellow Primeira Liga club FC Porto.
Söderström played 24 matches in his first season, but went on to serve consecutive loans for the remainder of his contract, mainly in that nation, as the northerners achieved consecutive European competition accolades. In January 2005, at 32 and having appeared in more than 200 overall games in Portugal, he left for Spain where he represented Córdoba CF and UD Lanzarote, in the second and third levels. He returned to his country in 2008 after 11 years, signing with Hammarby IF.
Söderström announced his retirement from football on 20 February 2011 at the age of nearly 38, after being released by Hammarby on a free transfer.
Söderström played five games for the Swedish national team over a period of four years, but never appeared in any major international tournament. He gained his first cap on 2 June 1998, starting and featuring 62 minutes in a 1–0 friendly win against Italy in Gothenburg.
