Van Biljon graduated from the University of Cape Town with a degree in Computer Science. He held engineering and research positions at LinkData, the Institute for Applied Computer Science and the National Research Institute for Mathematical Sciences.

Van Biljon co-founded Mosaic Software. Mosaic built the Postilion payment system, the first high-end payment transaction switch for commodity hardware and operating systems (Windows). Mosaic's investors included GE and Paul Maritz. The company became one of the top three payment processing software vendors in the world and was sold in 2004 to S1 Corp.
