We're looking for a Senior Software Developer to join the Elasticsearch - Search Relevance team. We collaborate across continents every day over email, GitHub, Zoom, and Slack. At our best, we write fast, scalable and intuitive software. Lead initiatives within Elasticsearch to produce an industry-leading search engine offering, supplying unparalleled speed and relevance in search.
Contribute to Elasticsearch full time, building new search features and fixing intriguing bugs, all while making the code easier to understand. Sometimes you'll need to invent a new algorithm or data structure. Or find one and implement it. Work with a globally distributed team of experienced engineers focused on the vector search capabilities of Elasticsearch.
Be an expert on Elasticsearch search relevance. Write idiomatic modern Java -- Elasticsearch is 99.8% Java!
Professional experience with search or vector databases, and you used HNSW, IVF, or other relevant algorithms and libraries on search platforms at scale.
You have solid skills in core Java and are conversant in the standard library of data structures and concurrency constructs, as well as other features like lambdas.
You work with a high level of autonomy and are able to take on projects and guide them from beginning to end. Bonus points if you've collaborated over the internet because that's harder. Double bonus points for asynchronous collaboration over the internet.



That's even harder, but we do it anyway because it's the best way we know how to build software.
You've used several data storage technologies like Elasticsearch, Solr, PostgreSQL, MongoDB, or Cassandra and have some idea how they work and why they work that way.
You possess the ability to collaborate across functions and teams and seamlessly transition between different projects, codebases, or teams based on business priorities
You've built things with Elasticsearch before.
You've worked with open source projects and is familiar with different styles of source control workflow and continuous integration.
Experience with data storage technology.
