Job Board/Software Engineer, Search Platform at Wikimedia Foundation
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

We welcome and cherish our differences.
The sum of all knowledge for every single human being; we can’t do that by leaving people out. Our vision is about more than providing universal access to all forms of knowledge. It’s about creating an inclusive culture. It’s about inviting others to join in and thrive with us. It’s about embracing human diversity. It’s about saying, “We see you and you belong with us.”
Our differences are precious; they make us smarter, stronger, more humble. They balance our biases and weaknesses. They open our minds. We do our best work when we understand a problem from all its perspectives.
We encourage others to do what we can’t, and we help them succeed. When voices are absent, ignored, or silenced, we seek them out. We are welcoming hosts, caring neighbors, and equitable allies. We don’t fear difference. We welcome it with curiosity, delight, and hope.
