Requirements:

You are highly proficient in Java, conversant in the standard library of data structures and concurrency constructs.
Experience troubleshooting complex issues.
You have solid software engineering foundations, with a proven track record of designing and delivering high-quality solutions.
A high level of autonomy. The distributed nature of the company offers freedom to work when and how you see fit, but also requires team members to work independently, and reach out for help when stuck.
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.

Nice to Haves:

You've built things with Elasticsearch before.
You have experience designing, leading and owning cross-functional initiatives.
You've worked with open source projects and are familiar with different styles of source control workflow and continuous integration.
You have past working experience with database, search engine, OS or cloud service development.

You'll be a full time Elasticsearch contributor, building scalable new features, fixing intriguing bugs and increasing the testing coverage, 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. Sometimes you'll need to get close to the operating system and hardware.
Tackling difficult issues, including performance or concurrency issues, and proposing solutions.
Collaborating in the open with the Elasticsearch team, Elastic Stack users, and other supporting open source projects. You'll work with community members from all over the world on issues and pull requests, sometimes triaging them and handing them off to other experts and sometimes handling them yourself.
Partnering with our support engineers on the harder problems.
You'll write idiomatic modern Java -- Elasticsearch is 99.8% Java!
