Informacje o stanowisku
Senior PostgreSQL Architect / Database Reliability Engineer (DBRE)
Mission of the Role
Stability, Scale, and Efficiency
We are looking for an engineer capable of designing and maintaining large-scale data systems (2TB+) while ensuring stability and cost efficiency. If your ideal system runs reliably because it was well-architected from the start, this role is for you.
Our environment is hybrid (On-premise, Azure, GCP). This is not an incident-response administrator role — we are seeking an architect who will take ownership of the full data ecosystem, implement a Database-as-Code approach, and demonstrate that query optimization is the most effective way to reduce cloud costs (FinOps).
Seniority & Collaboration
- Senior or higher level.
- Join the infrastructure team managing public cloud, on-premises systems, network, OS, and databases.
Contract Duration
- Engagement planned at least until the end of 2026, with possible extension.
Start Date
- Planned start: April 1, 2026.
- Deep knowledge of PostgreSQL internals: MVCC, WAL, Autovacuum under load, Query Planner.
- Experience with large-scale databases (2TB+): partitioning, bloat management, zero-downtime operations.
- Multi-cloud and hybrid environment experience: Azure Database for PostgreSQL, Google Cloud SQL, Linux-based PostgreSQL instances.
- Software engineering approaches: infrastructure as code, automation via custom tools and scripts.
- Pragmatic technology mindset: selecting stable, proven solutions and making decisions based on technical and economic justification.
Work Culture & Language Skills
- Remote-first work with weekly presence in Poznań office (Thursday).
- Polish for daily team communication, English for international projects.
- Emphasis on a No-Blame Culture: focus on process improvement and automation rather than assigning blame.
