The Wikimedia Foundation is looking for a Data Engineer to join our team, reporting to the Director of Data Engineering.

This includes everything from building scalable pipelines using big data technology to defining and creating a suite of datasets which adhere to our privacy principles.

We are a fully remote, internationally distributed team. When there isn’t a pandemic around, we see each other in person 2-3 times a year during one of our off-sites (the last few have been in places like Majorca, New York and Prague), the Wikimedia All Hands (once a year in San Francisco), or Wikimania, the annual international conference for the Wiki community.

Integrating data from multiple sources to gain insights in areas such as content, traffic, editors, readership and fundraising
Building scalable data pipelines in collaboration with other data engineers as well as teams across the foundation including product analytics, platform engineering, survey, research and machine learning teams
Designing the shared data platform that supports use cases for critical aspects of the Wikimedia mission: harassment prevention, image classification, bot detection, DDoS attacks flagging and many more
Building and maintaining public metrics and datasets
Implementing data quality monitoring that alerts the team of possible data issues
Implementing a data governance and lineage solution for all Wikimedia data

Skills and Experience:

2+ years of relevant industry experience
Advanced working knowledge of SQL, relational databases, query authoring, ideally in a variety of flavors (in our team alone we deal with MariaDB, HiveQL, CassandraQL, Spark SQL and Presto)
Experience with one or more programming languages such as Python, Scala, and Java
Experience building data pipelines using tools such as Airflow, Spark, Gobblin, Oozie, Yarn
Familiarity with stream processing systems using Kafka, Spark streaming and/or Flink
Excellent written and verbal communication skills
Strong interpersonal and collaboration skills
BS or MS degree, preferably in Computer Science, or equivalent work experience

Qualities that are important to us:

Commitment to the mission of the organization and our values
Commitment to our guiding principles
Commitment to diversity, equity, and inclusion
Cross-cultural sensitivity and awareness
Collaborative working experience

Additionally, we’d love it if you have:

Experience with Hadoop
Understanding of related disciplines including Machine Learning, Statistics, Privacy  and Algorithms
Experience working with site reliability engineers
