Becker's first international medal came with the German 4×100 metres relay team, when she anchored home a quartet including Sandra Roos, Birgit Brodbeck, and Carmen Bertmaring to the bronze medal at the 1993 European Athletics Junior Championships. She also finished seventh individually in the 100 m at that competition. At the 1994 World Junior Championships in Athletics, she was again a 100 m semi-finalist, but secured a silver medal with the relay team of Roos, Sandra Görigk and Esther Möller, finishing behind Jamaica.
