Our small team is passionate about making knowledge discoverable. We are responsible for Wikidata Query Service (a graph database that allows users to run arbitrary SPARQL queries on Wikidata) and for the search engine used on Wikipedia and its sister projects.
We are looking for a software engineer to help us bring the Search Platform team to the next level.
We use open-source tools as much as possible, and always open source our own work. Java, Python, PHP, and Scala make up most of our code, but we value using the right tool for the job. Our world is vast and can be complicated, so we value communication, enthusiasm, and an eagerness to learn.
You are responsible for:
- Work and communicate clearly and effectively within a small team that spans multiple time zones
- Help maintain, scale, and extend query services at the Wikimedia Foundation — this includes the Wikidata Query Service (WDQS) and our Elasticsearch-based search engine
- Improve the integration of Search, Wikidata Query Service, and the MediaWiki platform
Skills and Experience:
- Good working knowledge of software design principles
- Good understanding of how to scale applications, in terms of load, complexity, and performance
- Ability to work in a Linux server environment
- Write code in Java and PHP that stands the test of time
- Demonstrated experience in large-scale Java applications
- Be willing to travel occasionally - sometimes internationally - for team and organizational meetings
- Proficient English speaker
Additionally, we’d love it if you have:
- Degree in computer science, statistics, math, physics or other quantitative discipline; equivalent experience learned hands-on on the job also works
- Experience with graph databases
- Experience working on open source, collaborative development projects
- Understanding of free culture / free software / open source principles
- Exposure to applied machine learning (ML), deep learning, or natural language processing (NLP)
- Familiarity with statistics
- Experience with an internet software environment operating at scale; for example, messaging platforms that process hundreds of thousands of events per second
- Big thumbs ups if you are a contributor to Wikipedia
Show us your stuff! If you have any existing open-source software that you've developed (this could be your own software or patches to other packages), please share the URLs for the source. Links to GitHub, etc. are especially useful.
The Wikimedia Foundation is...
...the nonprofit organization that hosts and operates Wikipedia and the other Wikimedia free knowledge projects. Our vision is a world in which every single human can freely share in the sum of all knowledge. We believe that everyone has the potential to contribute something to our shared knowledge, and that everyone should be able to access that knowledge, free of interference. We host the Wikimedia projects, build software experiences for reading, contributing, and sharing Wikimedia content, support the volunteer communities and partners who make Wikimedia possible, and advocate for policies that enable Wikimedia and free knowledge to thrive. The Wikimedia Foundation is a charitable, not-for-profit organization that relies on donations. We receive financial support from millions of individuals around the world, with an average donation of about $15. We also receive donations through institutional grants and gifts. The Wikimedia Foundation is a United States 501(c)(3) tax-exempt organization with offices in San Francisco, California, USA.
