Senior Backend Engineer role owning technical problems and leading development for a managed ClickHouse service platform.
Обязанности
- We're looking for a Senior or Staff Backend Engineer to anchor our small, focused ClickHouse team. You'll own hard technical problems end to end on the platform behind our managed ClickHouse service - from database internals and backup/restore correctness to the data engineering tooling that connects ClickHouse to the wider ecosystem.
- This is a role with real technical ownership. You'll write RFCs and design documents that change how we build, scope and lead multi-quarter initiatives, and influence the product roadmap for ClickHouse and its ecosystem - streaming ingestion, CDC, benchmarking, and analytics tooling. You'll also mentor the engineers around you and raise the bar for how the team works.
- We expect you to be equally comfortable designing a new architecture and diving into a production incident - reading ClickHouse source code, untangling a replication race condition, or root-causing a flaky distributed test.
- Design and lead major platform initiatives: think coordination-service migrations (ZooKeeper → ClickHouse Keeper), backup/restore architecture, cluster topology, sharding, and node lifecycle management
- Build data engineering tooling around ClickHouse - streaming ingestion pipelines (Kafka → ClickHouse, Postgres → ClickHouse), schema conversion and evolution, integration frameworks, and fault-isolation between data sources
- Own the ClickHouse version lifecycle: qualify new LTS releases, diagnose upstream regressions, and take releases from early availability to GA
- Debug deep into the stack - ClickHouse internals (replication, access control, MergeTree, materialized views), distributed coordination, object storage (S3/GCS/Azure), DNS and networking, TLS
- Write RFCs and drive architectural decisions that extend beyond the team, including security and infrastructure changes
- Influence the roadmap: scope epics, break down initiatives into deliverable work, and shape what the team builds next - including commercial aspects like plans, sizing, and capacity
- Mentor engineers on the team through design reviews, code reviews, and pairing - multiply the team, don't just add to it
- Keep the lights on with pride: production incident response, observability improvements, CI performance, and test reliability are part of the craft
Требования
- Expert Python development skills - you write clean, production-grade async Python and have architected substantial systems with it, including decomposing large codebases into well-factored components
- ClickHouse experience - operating it at scale, query optimization, or upstream contributions
- C++ - ability to read and contribute to database engine code
- Deep database internals knowledge - replication, access control, storage engines, backup/restore semantics; you're comfortable reading database source code (ClickHouse is C++) to root-cause behavior
- Distributed systems depth - consensus/coordination services (ZooKeeper, Keeper), race conditions, cluster topology, and the failure modes of services running across nodes, AZs, and regions
- Data engineering experience - streaming pipelines, Kafka, schema management (Avro or similar), and the operational realities of moving data between systems reliably
- Strong Linux and cloud fundamentals - object storage (S3-compatible), networking/DNS, TLS/certificates, systemd-level debugging
- Track record of technical leadership - RFCs or design docs you've authored, multi-quarter initiatives you've scoped and led, engineers you've mentored
- Product sense – you can connect engineering decisions to customer impact, pricing, and roadmap priorities
- Experience with AI coding tools - you actively use AI-assisted development and help others get the most from it
- Fluent English – written and verbal
Будет плюсом
- CDC and analytics ecosystem experience - Debezium-style pipelines, Iceberg, lakehouse formats
- Benchmarking and performance engineering - capacity planning, sizing methodology
- Security engineering exposure – certificate management, access-control models

- We’re a global team of over 400+ people, working together to push the boundaries of open-source technology and multi-cloud solutions. Our vision is to help developers, builders, and creators bring their ideas to life with speed and simplicity, by providing a cloud data platform that makes open-source databases, search, streaming, and application infrastructure easily accessible to everyone.
- Real ownership. The team is small (you plus two engineers) - your designs, RFCs, and roadmap input directly determine what gets built.
- Genuine depth. Database internals, distributed coordination, streaming data pipelines, and backup correctness - not CRUD apps.
- Ecosystem scope. You shape not just the managed service but the data engineering tooling around ClickHouse - ingestion, CDC, benchmarking, integrations.
- Modern tooling. Strict type checking, automated formatting, security scanning, and AI-assisted development are the norm.
- Helsinki-based, hybrid. The team is in the office regularly; you'll work closely together.
