In 1625 he became director of the Levantine trade. At some time Jan Bicker became the city's inspector of the ropes. Together with his brothers, he exerted a great influence on the economic climate in Holland. The Bicker family was Calvinist and focused on Amsterdam's economic boom.
From 1628 Jan Bicker lived at Keizersgracht 221 and invested specifically at Bickerseiland which he bought from the city in January 1631. Within twelve years he had ship wharfs, (ware)houses and a tower built so he could watch his project. In 1634 he invested in Cayenne as patroon. Around 1638 he and Abraham Boom supplied ships of war to France, ordered by Cardinal Richelieu. From the late 1630s they came into opposition to the stadtholders.
In 1647 and 1651 Jan was elected schepen in the city council. Jan Bicker was given the position of burgemeester in February 1653, but did not keep it for long due his death on 9 May; he was buried in Westerkerk. With a fortune of 717,000 guilders, Bicker was one of the richest people of the Golden Age. He owned various country estates outside Amsterdam:
Akerendam near Beverwijk, as well as De Eult and Hooge Vuursche in Baarn.

The Bicker family was one of the oldest families of Amsterdam and belonged to the leading regent-oligarchy. They were a major trading family involved in the VOC and WIC. The Bickers were the most powerful family in Amsterdam and decisively determined the fortunes of the city. The Bicker-De Graeff family-faction became the strongest competitor in the years after the Dutch uprising. Through their work on the Amsterdam City Council, the Dutch East India and West India Company, the schutterij and the Wisselbank, the Bickers gained enormous influence on politico-economic self-determination in the Dutch Republic. The Bicker brothers had a firm grip on world trade, trading on the East- and the West-Indies, the Baltic and the Mediterranean.
