Description

We're looking for a Senior Software Engineer to join our Elasticsearch - Distributed Systems team. As a member of this team, you'll focus on improving Elasticsearch's components that support concurrent and consistent indexing across multiple machines.

Your responsibilities will include:

Improving Elasticsearch's components that support concurrent and consistent indexing across multiple machines. Maintaining our cluster coordination system to keep performance high even though nodes come and go from the cluster and data moves around, while maintaining the safety and liveness properties of the system as a whole. Pushing the limits on the number of shards, nodes, and petabytes that Elasticsearch can handle today. Looking into all kinds of issues, including performance or concurrency issues, and proposing solutions. Supporting our support engineers with the harder problems.

To be successful in this role, you'll need a strong background in distributed systems and consensus algorithms. You should also have strong skills in core Java and be conversant in the standard library of data structures and concurrency constructs, as well as newer language features.

Bonus points will be given if you have experience with data stores, search, analytics, Lucene, and asynchronous event-driven network frameworks such as Netty.

At Elastic, we take care of our people. We strive to have parity of benefits across regions and believe taking care of our people is the right thing to do. We offer competitive pay, health coverage for you and your family, flexible locations and schedules, generous vacation days, and more.
