After working for the BFV (Berlin Football Association) and the DFB (German Football Association), the experienced coach returned to Köpenick in 2022, when she took over the role of the first full-time head coach and head of the women's and girls' department, before Jennifer Zietz took over the management of the department in January 2023 allowing Poese to focus exclusively on her duties as head coach.

We will support her in the best possible way with the strength of the club.”

“Union is my footballing home, I have spent a large part of my career here as a player and was able to take my first steps here as a coach,” said Poese, meanwhile. “Continuing to follow the path of professionalisation is a great task and an honour. I am looking forward to it and, together with the team, we will do everything we can to achieve our goals."

“We have made great strides in the development of professional women's football over the last two years and have been able to quickly translate the significantly improved conditions and structures into sporting success,” said Union’s director of women’s and girl’s football, Jennifer Zietz. “As head coach, Ailien has played a major role in this. It is therefore only logical to continue our cooperation and tackle the next goals. I look forward to continuing our work.”
