Elastic - Principal Software Engineer

• You have implemented novel techniques in vector similarity on a search platform with a large user base or progressed the field of academic research in vector similarity information retrieval. • Professional experience with vector similarity and vector databases, and you used HNSW, IVF, or other relevant algorithms and libraries on search platforms at scale. • You have strong 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. This covers both technical design and working with other engineers to develop needed components. • You're comfortable developing collaboratively. Giving and receiving feedback on code and approaches and APIs is hard! 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 have excellent verbal and written communication skills. Like we said, collaborating on the internet is hard. We try to be respectful, empathetic, and trusting in all of our interactions. And we'd expect that from you too. • You've built things with Elasticsearch before. • You've worked with open source projects and are familiar with different styles of source control workflow and continuous integration. • Experience with data storage technology. • You have experience designing, leading and owning cross-functional initiatives. • Additional Information - We Take Care of Our People: • As a distributed company, diversity drives our identity.
