Principal Software Engineer - Postgres

Clickhouse; Deutschland; Remote; EUR 120.000 - 180.000; Vollzeit

Zusammenfassung

ClickHouse is seeking a Principal Engineer to push the boundaries of database internals and systems programming. The role emphasizes deep PostgreSQL expertise, end-to-end delivery of large-scale infrastructure, and autonomy in a fast-paced environment.

You will influence architecture across storage, replication, and query execution, mentor engineers, and extend Postgres internals for reliability and cloud-native integration.

Qualifikationen

• 10+ years of experience building systems software in C/C++ or Rust.
• Deep knowledge of PostgreSQL or other DB engine internals.
• Strong understanding of concurrency, operating systems, and performance engineering.
• Proven ability to ship large-scale systems end-to-end.
• Experience contributing to open-source databases is desirable.
• Pragmatic problem solver with a bias for simplicity and measurable impact.
• Thrives in a high-autonomy, high-velocity environment.

Aufgaben

• Lead design and implementation of core database infrastructure features across storage, replication, and query execution.
• Contribute to and extend Postgres internals to improve reliability and scalability.
• Prototype and build extensions that integrate with cloud-native infrastructure.
• Mentor senior engineers and drive architectural direction for high-impact systems.
• Operate with significant autonomy and ownership from concept to production.
• Collaborate with product and platform teams to deliver robust developer experiences.

Requirements

• 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
,
• 10+ years of experience building systems software in C/C++ or Rust (Go experience a plus)
,
• Deep knowledge of PostgreSQL or other database engine internals, including storage, execution, or replication subsystems
,
• Strong understanding of concurrency, operating systems, and performance engineering
,
• Proven ability to ship large-scale systems or core infrastructure features end-to-end
,
• Experience contributing to open-source databases or similar complex systems is highly desirable
,
• Pragmatic problem solver with a bias for simplicity and measurable impact
,
• Thrives in a high-autonomy, high-velocity environment

What the job involves

• ClickHouse is expanding its capabilities in the database systems domain, building next-generation infrastructure that redefines performance, scalability, and developer experience
,
• 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
,
• 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
