Job summary

Elastic is seeking a Senior Software Engineer for the Elasticsearch - Distributed Systems team, focusing on scale, performance, and resilience in a Serverless context. You will tackle deep distributed systems challenges around node communication, indexing, and data management across nodes.

You will own end-to-end development, optimize coordination, and push the system to handle ever-larger shard and petabyte-scale workloads, collaborating across teams to deliver robust solutions.

Qualifications

• Strong background in distributed systems and consensus algorithms.
• Proficient in core Java and familiar with concurrency constructs and standard data structures.
• Deep understanding of algorithms and their practical applications in large-scale systems.

• Improve components that support concurrent and consistent indexing across multiple machines.
• Maintain cluster coordination to preserve performance as nodes join/leave and data moves around.
