Matoušek was born in Prague. In 1986, he received his Master's degree at Charles University under Miroslav Katětov. From 1986 until his death he was employed at the Department of Applied Mathematics of Charles University, holding a professor position since 2000.

In 1998 he was an Invited Speaker of the International Congress of Mathematicians in Berlin. He became a fellow of the Learned Society of the Czech Republic in 2005.
Matoušek's paper on computational aspects of algebraic topology won the Best Paper award at the 2012 ACM Symposium on Discrete Algorithms.
Aside from his own academic writing, he has translated the popularization book "Mathematics: A Very Short Introduction" by Timothy Gowers into Czech. He was a supporter and signatory of the Cost of Knowledge protest.
