Summary from the posting
The Mozilla Firefox Performance team is a community of engineers who care deeply about delivering the fastest browser possible. We are the team responsible for making all parts of the browser go fast.
Our team is geographically-distributed, and working in the open is the norm. We contribute to the code driving the Firefox browser on a number of platforms - Windows, Android, Linux, and macOS. Our focus is on finding and fixing things that slow down the browser as well as helping other teams write fast and reliable code to make Firefox excellent for users.
Do you value curiosity and enjoy finding a needle in a haystack? Do you approach problems by looking at the system as a whole?
This is a short summary. The full description, requirements and the application form are on Mozilla's own career page.
