About the role

Senior Software Developer focused on performance tuning for Elasticsearch, contributing to performance engineering initiatives, profiling, benchmarking, and AI-assisted optimization harnesses to improve performance, scalability, and reliability across distributed systems.

Responsibilities

  • Contributing to core performance engineering initiatives from development to production, delivering impactful optimizations and executing architectural and code-level performance improvements.
  • Implementing foundational performance models and methodologies for complex, distributed systems.
  • Supporting optimization strategies to keep Elasticsearch performant, predictable, and scalable in diverse environments.
  • Profiling and analyzing system behavior to identify bottlenecks in logging, metrics, vector search, and ES|QL.
  • Ensuring robust performance benchmarks and regression detection for both stateful and stateless (Serverless) architectures.
  • Collaborating with peers to apply performance-focused development practices to new features.
  • Contributing to automation efforts with AI-assisted optimization harnesses for profiling, hypothesis testing, and benchmarking.
  • Providing technical guidance and peer reviews to engineers to foster technical excellence.

Qualifications

  • Deep knowledge of Java internals and JVM memory management; ability to write high-performance, thread-safe, lock-free code in large open-source and enterprise codebases.
  • Proven experience profiling and optimizing distributed systems, including benchmarking tools (e.g., JMH, Rally), identifying regressions, and implementing algorithmic or hardware-aware optimizations.
  • Solid understanding of distributed systems architecture, including partition tolerance, cluster state propagation, and scaling challenges in large-scale data stores.
  • Proven track record of using AI or advanced tooling to accelerate optimization, debug complex performance issues, and automate benchmarking workflows.
  • Ability to collaborate effectively within a team and across functions; capable of transitioning between projects, codebases, or teams based on priorities.
