About Josh Aas


I founded Internet Security Research Group (ISRG), the non-profit entity behind the Let’s Encrypt certificate authority, in 2013. I’ve been ISRG’s Executive Director and chair of the corporate board since it was created.

I worked on Gecko and Firefox as part of Mozilla’s platform engineering group for many years. After that I worked for Mozilla as a senior strategist, finding solutions for difficult problems.

I grew up in Duluth, MN. I graduated from Macalester College with majors in English Literature and Computer Science. I currently live in Minneapolis, MN.
