After his first engagements at the Stadttheater Konstanz, Staatstheater Braunschweig and at the Residenztheater in Munich, he was discovered by Hans Peter Doll, the director of the Heidelberg Theater.

Under Doll, he next appeared at the State Theater in Stuttgart, where there was great discussion about the possible sympathies of director Claus Peymann [de] for members of the Red Army Faction.

He then moved to the Schauspielhaus Bochum with Peymann and in 1983 with the role of Hermann in Die Hermannsschlacht by Heinrich von Kleist was engaged at the 20th Berliner Theatertreffen.

[2] Over the next years, Voss collaborated with directors like Luc Bondy, George Tabori and Peter Zadek.

[5] Prior to his death, Voss was Bruno Ganz's original choice to succeed him as holder of the Iffland-Ring, which by tradition distinguishes "the most significant and most worthy actor of the German-speaking theatre".
