Rudwaleit began playing football for enterprise sports community BSG Einheit Woltersdorf.

Rudwaleit made his first appearance with the first team of BFC Dynamo as a 19-year-old against FC Carl Zeiss Jena in the eighth matchday of the 1976–77 DDR-Oberliga on 22 October 1976.

He became East German champion ten times in a row from 1979 to 1988 with BFC Dynamo.

in front of 26,000 spectators at the Friedrich-Ludwig-Jahn-Sportpark in the penalty shoot-out between BFC Dynamo and Aberdeen F.C.

BFC Dynamo then won the penalty shootout 5–4 after a decisive goal by Norbert Trieloff and advanced to the second round.

Rudwaleit was insulted as "Bodo Eierkopp" by supporters of opposing teams during the East German era.

Coach Helmut Jäschke then decided to give goalkeeper Oskar Kosche a chance in the next few matches.

Kosche made his debut in the cup match against HFC Chemie in the 1989–90 FDGB-Pokal on 11 November 1989.

[15][16] A process of great sociopolitical change had begun in East Germany and parts of the Berlin Wall were opened on 9 November 1989.

Rudwaleit eventually backed down from his decision to retire and instead joined BSG Stahl Eisenhüttenstadt on 1 January 1990.

[17] He quit the Volkspolizei and returned his membership card of the Socialist Unity Party at the same time.

[14] Rudwaleit became the first-choice goalkeeper of the successor club Eisenhüttenstädter FC Stahl in the 1990–91 NOFV-Oberliga.

Originally Rudwaleit had only signed up for a newly formed senior team at FV Erkner 1920.

BFC Dynamo had difficulties putting a team together, as the match was played in the middle of the week.

Only nine players from the reserve team were available, the rest were either tied to their military service or prevented from participating because of work.

During the match he also got to play together with his son Robert Rudwaleit, who had then made his third appearance for BFC Dynamo.

In such a case, Rudwaleit has never previously conceded more goals during a match for BFC Dynamo, his negative record until then was 0–5 against SV Werder Bremen in the 1987–88 European Cup.

Rudwaleit initially took over as interim coach in the first match after the resignation of Back, away against FC Schönberg 95 on 21 April 2005.

[29] Rudwaleit was appointed new sports director of BFC Dynamo at the general meeting on 6 June 2006.

Rudwaleit has since served as goalkeeping coach at SV Woltersdorf and FV Erkner 1920.

[41] He was the first-choice goalkeeper of the national football team, until René Müller became the undisputed number one in the middle of the 1980s.
