Search Engineer, Tumblr (Content Discovery)
Tumblr launched in 2007 with the belief that people need a place to say what they want, be who they want, and connect over what they love. We continue to build out Tumblr as a platform for free expression, individuality, and human connection. A key part of fostering an ecosystem of free expression is getting the right content in front of the audience who is most interested in it.
Tumblr’s Search Team is looking for a motivated and independent engineer who is excited to develop and maintain our algorithms to surface the best content from billions of posts (videos, GIFs, memes, etc) and give users control to sort, filter, and explore it.. You’ll have the ability to influence the content included in thousands of sessions per second, and will solve problems pertaining to the retrieval, ranking, filtering, and personalization of content viewed on Tumblr through mobile applications and on the website. Help us make social media a beautiful experience.
Engineers at Automattic are responsible for the engines of Automattic: a variety of codebases and systems devoted to making the web a better place.

- Build out new content datasets using Elasticsearch, Hadoop, Kafka, Druid, Flink, and/or Spark.
- Maintain a fleet of servers via Puppet and Kubernetes to keep the search and discovery services running and performing well.
- Train and deploy machine learning models for classification, filtering, and ranking.
- Work closely with our Systems and SRE teams to craft and maintain architectures that support efficient development and deployment of your ideas.
We are looking for:
- Experience deploying and maintaining production search systems.
- Familiarity with Elasticsearch, Solr, or Lucene.
- Proficiency in PHP, Java, and/or Scala; deep knowledge in Information Retrieval, and/or recommendation algorithms.
- Familiarity with Hadoop and MapReduce, including frameworks such as Spark, Hive, or Scalding.
- A desire to build a safe and inspiring search experience for our users and a passion to help everyone express their true selves, regardless of their income, gender, race, politics, language, or where they live in the world.
- Excitement to join a globally distributed team. Familiarity with remote work is welcome.
