Accordingly, Job reached the zenith of his influence in the period starting with the death of Béla IV, when he also held temporal offices in addition to his bishopric.
King Béla IV of Hungary promoted Job to the provostship of the royal Székesfehérvár Chapter when the incumbent, Achilles from the kindred Hont-Pázmány was appointed bishop of Pécs in 1251.
Although the pope permitted a mortgage of 15 Venetian marks of gold, Bishop Job sent back his canons to achieve an increase.
According to a royal charter of 1331, Job was also involved into a conflict with the collegiate chapter of Požega where he attempted to fill the vacancies in order to strengthen his influence over the influential ecclesiastic institution of his diocese.
Job maintained a close relationship with Cardinal Stephen Báncsa whose relatives and followers one after another received prebends in the chapters of the diocese of Pécs.
Bishop Job joined the party of the "junior king" Stephen V against his father, Béla IV when a civil war broke out in the 1260s.
When Austrian troops invaded Hungary in the next year, he expelled his fellow bishop Denis from the castle of Győr and made himself the captain of the fortress.
The monarch also awarded Job with significant land grants, thus he became the owner of the villages Perlász, Rozsozsna, Somkút (in modern Pelsőc), Süvéte and the nearby Liponok by the end of his life.
