Staff Database Administrator at Wikimedia

This is an ideal role for a senior database expert with at least 6 years of experience managing large-scale SQL environments. You should have a deep mastery of MariaDB or MySQL, specifically handling complex replication topologies and performance tuning for high-traffic websites. This position sits within the SRE Data Persistence team, so a background in site reliability and on-premise hardware planning is essential. As a staff-level contributor at a major global non-profit, you will directly support the infrastructure of Wikipedia. The role offers significant flexibility as a remote-first position spanning over 40 countries, with a transparent salary range (adjusted by location) and a mission-driven culture. You’ll be working on "bare-metal" hardware and open-source projects, offering a technical challenge rarely found in standard cloud-only environments. **You might be a good fit if you:** * Have advanced proficiency in MariaDB/MySQL and can optimize complex queries under heavy load. * Are comfortable participating in a 24/7 on-call rotation for global production systems. * Can automate workflows using Python and configuration management tools. * Enjoy working independently across asynchronous, globally distributed teams.
