Coming up through the Westerlo youth ranks, Seigers helped the club to a European play-offs place in the 2022-23 Belgian Pro League under Jonas De Roeck. The following season, Seigers was one of many to leave on either a permanent or temporary basis, joining Zulte Waregem on loan on 5 August 2023.[2]
Zulte's bid to earn promotion back to the top flight saw them denied in the promotion play-offs, and Seigers returned to Westerlo for the 2024-25 campaign. Westerlo won their first three games of the season over Cercle Brugge, KV Mechelen and Union Saint-Gilloise to go top of the Pro League for the first time in their history, two of those against European qualifiers.
