Wikimedia Commons

Wikimedia is a non-profit organization dedicated to the advancement of free knowledge. It hosts a variety of projects, including Wikipedia, the world's largest online encyclopedia, as well as other projects in multiple languages. It is supported by a global network of volunteers and staff who work to make knowledge freely available to everyone. The organization's mission is to empower and engage people around the world to collect and develop educational content under a free license or in the public domain, and to disseminate it effectively and globally. It is funded by donations from individuals and institutions, and supported by a variety of partnerships with organizations and universities around the world.

The project has grown very rapidly since its inception. On May 24, 2005, it reached a milestone of 100,000 uploaded media files (excluding thousands of weather and market data images for Wikinews ).engineering.fandom.comIt was also the first Wikimedia project to use MediaWiki 1.4. The default language for the Commons is English, but the interface can be configured (in user preferences) to use any other language.

Wikimedia Commons reached 10 million files on April 15, 2011. [1] The Wikimedia Foundation was given money to make it easier for people to use their websites.simple.wikipedia.orgFor every file on Wikimedia Commons, the person who made it has to let everybody use it and change it as much as they want, including companies (see Creative Commons ).

See First steps/Upload form for further instructions on uploading to Commons. More general help can be found at Wikimedia Commons Help.en.wikipedia.orgAnother advantage of Wikimedia Commons is its category system that helps to organize and make images easy to find. An important caveat to Wikimedia Commons is that they do not accept fair use images.

The Wikimedia Foundation is looking for a Site Reliability Engineer (Database) to join our SRE team to build, optimize and support the platform serving the world’s favorite encyclopædia to millions of people around the globe. Wikipedia and its sister projects are a globally distributed architecture powered strictly by Free and Open Source software. The stack has MediaWiki at its core and... MariaDB as its data store, surrounded by an ecosystem of microservices in PHP, NodeJS, Python, Go and Java.

The Wikimedia community continuously generates text content in the form of new articles, revisions and discussions. As part of our team you would have the opportunity to solve the storage, scaling, access and backup challenges that Wikipedias’ scale provides.

We currently use self-hosted MariaDB as our main RDBMS. Our goal is configuring and managing the database infrastructure in a way that maximizes the service uptime for Wikimedia projects’ users while at the same time simplifying the operational processes, automating repeatable tasks and applying industry best practices.

We are a globally distributed and diverse team of engineers with a drive to explore, experiment and embrace new technologies. If you find what we do interesting, if you are up to the challenge of improving the reliability and delivery of one of the Internet’s top 10 websites, and you enjoy the idea of working in a remote-first role, we may be the right place for you.

You are responsible for:
• Operate and improve the RDBMS systems serving Wikimedia projects
• Respond to common database issues, following documented procedures
• Collaborate with SRE and other teams across the organization to ensure their specific database needs are met on an ongoing basis
• Perform day-to-day operational/DevOps tasks on Wikimedia’s public facing infrastructure (deployment, maintenance, configuration, troubleshooting)
• Implement and utilize configuration management and deployment tools
• Monitor systems, services and service clusters, optimize performance and resource utilization
• Participate in incident response, diagnosis and follow-up on system outages or alerts across Wikimedia’s production infrastructure
• Share our values and work in accordance with them

Skills and Experience:
• 2+ years experience in a DBA role as part of a team
• 3+ years experience with Linux in a production environment
• Knowledge and experience of (Free and Open Source) RDBMS (preferably MariaDB or MySQL) administration (understanding of and experience with replication is essential) and support, debugging query performance and schema design
• Comfortable with shell and at least one of the scripting languages used in an SRE/Operations engineering context (Python, Go, Bash, Ruby, etc.)
• Passion for automating tasks and processes
• Strong English language skills and ability to work independently, as an effective part of a globally distributed team
• B.S. or M.S. in Computer Science or equivalent work experience

Additionally, we’d love it if you have:
• Experience working with or as a part of SRE/Operations/DevOps teams
• Experience with NoSQL products (Cassandra, Redis, Elasticsearch, etc.)
• Experience with LAMP stack technologies (PHP/HHVM, memcached/redis, MySQL) - MediaWiki familiarity would be great!
• Developing Free and Open Source software, or being part of an open-source community
