Around 1290, Job joined the allegiance of the powerful lord Amadeus Aba, becoming his "familiaris". By that time, Amadeus ruled "de facto" independently the northern and north-eastern counties of the Kingdom of Hungary, including Ung and Bereg counties, where Job's lands mostly laid. Amadeus Aba's political orientation also determined Job's affiliation and relationship to the monarchs. Ladislaus' successor, Andrew III of Hungary enjoyed the support of Amadeus Aba during his reign. Job fought in the royal military campaign against the Duchy of Austria in the summer of 1291. Therefore, Andrew III confirmed the former land donation of Komlós for Job in July 1291. At the end of his life, Job became vice-"ispán" of Bereg County with the title of "ispán" in 1308. The county was also administered by the "gens" (clan) Aba. Job Csicseri died soon, in 1309 or 1310. His sons already appeared individually during an act of domination in early 1311. They remained supporters of the Aba clan even after the assassination of Amadeus Aba in September 1311, and they had fought in the Battle of Rozgony against the royal army of Charles I in June 1312. After the defeat, Michael (Mokó) and Dominic swore loyalty to the Hungarian monarch and were elevated into administrative offices in Ung County, contributing to the survival of the Csicseri family and its future cadet branches.
