Operations Engineer/Database Administrator
Wikimedia Foundation - San Francisco, CA

... an experienced Database Administrator who would love to manage the world's free knowledge.

Wikipedia is currently a reader-centric site (ranked 5th worldwide in traffic, has about 480 million unique visitors/month, and a substantively active editing population of 100,000 individuals in a given month). That said, database changes need to be reflected with minimal latency, and there is significant emphasis on reliable storage, backups, query performance, publicly available data-sets, etc. We anticipate that our database and storage needs will grow as we continue to deploy new/improved functionality for participation (easier editing, improved media uploading, etc.).

You're excited about joining a small veteran operations team in a non-profit organization with a huge global impact. You enjoy working with open source solutions, solving complex problems autonomously, while flexibly working with your colleagues (including volunteers) who may be at the opposite site of the globe.
