Wikimedia's goal is to provide every single person with the sum of all human knowledge and MariaDB/MySQL is how we store most of it. You will be joining a small mission driven team of talented highly experienced engineers. As one of the most highly trafficked sites, there is literally nowhere else serving as many page views per engineer. As a Database Administrator at the Wikimedia Foundation, you will be responsible for the wellbeing of our relational data and the database systems they reside on, including the availability and performance. You should be able to troubleshoot, benchmark and test new builds of MariaDB and MySQL, plan for disaster recovery, and improve and maintain backups. This is a unique opportunity to have a huge impact. Our work is important, and it’s used by hundreds of millions of people.
