Dijsselhof will begin his new role in January 2018, replacing Urs Rüegsegger who announced in May 2017 that he would be stepping down.
Prior to joining SIX, Dijsselhoff had been at Euronext, most recently as a COO. He also served as interim CEO for a spell in 2015. Before this he spent time working at ANZ Australia & New Zealand Banking Group, and was head of group operations for Asia Pacific for the Royal Bank of Scotland.
Romeo Lacher, chairman of the board of directors at SIX, said: "I am delighted to have found in Jos Dijsselhof an experienced manager for SIX with strong leadership qualities and an outstanding track record.”
“I would also like to thank Urs Rüegsegger for his service and dedication. Under his leadership, SIX was able to lay a solid foundation, and I am confident that Jos Dijsselhof will build on this and successfully lead SIX to further successes."
In addition, the board of directors has decided to simplify SIX’s organisational structure, in a bid to create a “strong, shared financial market infrastructure in Switzerland”.
As part of the reorganisation, SIX will bundle all activities in its securities business, merging its exchange trading and post-trading units into one and providing a single source for securities trading services.
Elsewhere, SIX will restructure is payments business, providing an infrastructure for interbank payments for connections to the single euro payments area.
SIX is also looking to capitalise on its data business, in response to demand from banks for higher-quality international reference data.
The group hope the measures will be fully implemented by Q2 2018.
Lacher saidd: "SIX has developed very successfully since its inception. What we are doing now is setting the course for SIX to continue to play a major part in assuring the quality and success of the Swiss financial centre."
