He took employment in the Hague around 1422 when he was already a master painter with workshop assistants, and was employed as painter and valet de chambre with John III the Pitiless, ruler of Holland and Hainaut. After John's death in 1425, he was later appointed as court painter to Philip the Good, Duke of Burgundy, working in Lille until he moved to Bruges in 1429 where he lived until his death.
