[3] Her mother, Camelia Voinea, is a former artistic gymnast who competed at the 1988 Summer Olympics and won a silver medal with the Romanian team.

In March she competed at the Doha World Cup where she won gold on balance beam and floor exercise.

[8] In October Voinea competed at the 2023 World Championships alongside Ana Bărbosu, Lilia Cosman, Amalia Ghigoarta, and Andreea Preda.

Individually she won silver medals on balance beam and floor exercise, behind Manila Esposito on both.

[10] At the 2024 Olympic Games Voinea helped Romania finish seventh in the team competition.

As a result Chiles was initially awarded the bronze medal, with Bărbosu in fourth, and Voinea in fifth.

[14] Voinea's appeal was rejected as her coach did not submit an inquiry about the neutral deduction during the event final.

[15] Bărbosu's appeal, however, was accepted as the CAS found that Chiles' inquiry was submitted four seconds past the one minute deadline.
