Sandomierski's career began atJagiellonia Białystok, starting in the reserve side from 2006. He played in four games and then was loaned out toLech Poznań. He made two appearances in the fourth division, after which he returned to Jagiellonia. In the 2007–08 season, due to an injury to Jacek Banaszyński, Sandomierski made hisEkstraklasa debut againstCracovia in which he conceded two goals. By the end of the competition, he appeared in four other matches. Sandomierski then sustained a serious injury which excluded him from play for half a year. In January 2009, he was loaned toRuch Wysokie Mazowieckie, where he played as a first choice goalkeeper. Prior to the 2009–10 season, he returned to Białystok. Sandomierski got his chance for Jagiellonia afterRafał Gikiewicz suffered a poor run of form.[3] During his time at Jagiellonia, for six matches in a row, Sandomierski kept a clean sheet. His streak lasted 564 minutes, a club record, and ended in a clash withRuch Chorzów.[3]
