## Description

Lead design and implementation of advanced systems features for Postgres, focusing on performance optimization and scalability. Mentor engineers and drive architectural direction for large-scale database systems., ClickHouse is expanding its capabilities in the database systems domain, building next-generation infrastructure that redefines performance, scalability, and developer experience. We're looking for a Principal Engineer with deep expertise in systems programming and database internals - particularly Postgres - to help us push boundaries in how databases are built and operated at scale.

This is a strategic and high-impact role for an engineer who can work independently across complex technical areas: from storage and performance optimization to distributed coordination and extension development. You'll shape critical components of our data platform, mentor other engineers, and drive architectural direction for systems that serve massive workloads.
What You'll Do

 * Lead design and implementation of advanced systems features across areas like storage, replication, query execution, and performance optimization.
 * Contribute to and extend Postgres internals - improving reliability, scalability, and efficiency.
 * Prototype and build extensions that expand Postgres's core capabilities and integrate with cloud-native infrastructure.
 * Collaborate with product, infrastructure, and cloud platform teams to deliver robust, developer-friendly experiences.
 * Profile and optimize database performance using low-level instrumentation and benchmarking.
 * Provide technical leadership, set standards for engineering excellence, and mentor senior engineers.
 * Operate with significant autonomy and ownership - driving projects from concept to production.
