Database Architect Full-time

DATABASE ARCHITECT

Summary

Wikimedia is looking for a Principal Database Architect to join our SRE team to design, build, optimize and support the platform serving the world’s favorite encyclopedia 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, surrounded by an ecosystem of microservices in PHP, NodeJS, Python, Go and Java.

The Wikimedia developers and community continuously expand and improve the software powering the Wikimedia projects. The common step in this process is finding optimal ways of storing data and fine-tuning the code that interacts with data storage systems (including schema and query optimization).

We currently use MariaDB as our main RDBMS and Cassandra as the dominant NoSQL solution. We are interested in finding new and improved ways of utilizing the capabilities of the existing stack as well as researching and potentially implementing other similar products. To achieve these goals we are looking for a candidate with strong experience, both hands-on and in a consulting capacity, in designing, developing and operating large scale database systems with complex dependencies.

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, Wikimedia may just be the right place for you.

You are responsible for:

Working with developers, SREs and other teams, providing guidance on optimizing queries, schema design and overall data strategy.
Assisting at every step of the architectural design and development lifecycle of new services and making them operate at scale
Designing, improving and operating the RDBMS and NoSQL systems serving Wikimedia projects
Researching, testing and benchmarking new RDBMS and NoSQL solutions
Responding to common database issues, following documented procedures
Assisting in or leading incident response, diagnosis and follow-up on system outages or alerts across Wikimedia’s production infrastructure
Mentoring peers in your areas of technical and operational strength
Sharing our values and work in accordance with them
Skills and Experience:

Deep knowledge of (Free and Open Source) RDBMS (MariaDB, MySQL) administration (good understanding of and experience with replication is essential)
Deep knowledge of debugging query performance and schema design
Strong programming language skills and experience designing and developing software using relational databases at large scale
Familiarity with (Free and Open Source) NoSQL products (Cassandra, Redis, Elasticsearch, etc.)
Strong requirement analysis and problem solving skills
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 SRE/Operations/DevOps teams
Experience with shell and scripting languages used in an SRE/Operations engineering context (Python, Go, Bash, Ruby, etc.)
History of automating tasks and processes, identifying process gaps and finding automation opportunities
Low level systems troubleshooting and debugging (CPU/memory profiling, C/C++ experience, in-depth Linux knowledge)
Experience with LAMP stack technologies (PHP/HHVM, memcached/redis, MySQL) – MediaWiki familiarity would be great!
Some experience developing Free and Open Source software, or being part of an open-source community
