Matt Brandt

Interop Engineering Manager


A psychologist who became a software developer, who wandered into test engineering, and then wandered into middle management. I work within the Test Engineering group. I find it an absolute thrill to work for Mozilla and to help individuals thrive on teams that are doing impactful work.

My group is currently focused on helping Mozilla reach a 4 week release cycle for Firefox. We're doing this by combining the super powers of two products; Iris and Taskcluster. Iris is a test automation harness that our QA team uses to test Firefox. Taskcluster/Treeherder is Mozilla's CI.

If you would like to get involved on any of Mozilla's projects or be introduced to our community, reach out to me.
