Leveraging your deep distributed systems expertise to design, build, and operate core pieces of our next-generation Serverless Elasticsearch offering, directly impacting the experience of customers worldwide.
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.
Owning operational investigations end-to-end, until performance or stability issues are successfully resolved.
You have strong skills in core Java and are conversant in the standard library of data structures and concurrency constructs, as well as newer language features.
