Responsibilities
- Owning core performance engineering initiatives from architecture to production, focusing on the delivery of high-impact optimizations.
- Leading the technical design, plan, and execution for major architectural and code-level performance improvements.
- Developing foundational performance models and methodologies for complex, distributed systems.
- Driving optimization strategies to ensure Elasticsearch remains 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 across the company to embed performance-first thinking into new features from the outset.
- Drive automation efforts by designing and building AI-assisted optimization harnesses that streamline profiling, hypothesis testing, and benchmarking.
- Mentoring and coaching other engineers, fostering a culture of technical excellence and performance-aware development.
Requirements
