We strive to make a meaningful difference in diverse sectors such as insurance, banking, healthcare, retail, and manufacturing. Our passion for cutting-edge and disruptive technologies, as well as our shared values and strong principles, are what motivate us. We are a community of engineers and senior advisors who work with our clients across industries, playing a deep and meaningful role in accelerating and realizing their vision and strategy.\nAbout the position\nAs a Senior Database Administrator (DBA) with DevOps expertise within Advanced Analytics Team, you will be the primary owner of database health, reliability, and the full lifecycle of database artifacts across production AI systems. This is not a traditional DBA role - you will bring a strong DevOps mindset to database operations, treating schema migrations, stored procedures, configuration, and database infrastructure as versioned, tested, and continuously delivered artifacts.\nKey responsibilities:\nOwn the database artifact lifecycle: version-control all database objects (schemas, migrations, stored procedures, functions, views, roles) and manage their delivery through CI/CD pipelines using tools such as Flyway, Liquibase, or sqitch.\n\nDesign, implement, and maintain PostgreSQL database schemas: normalisation, indexing strategies, partitioning, constraint design, and schema evolution patterns that support zero-downtime migrations.\n\nBuild and operate database CI/CD pipelines in collaboration with DevOps: automated migration testing, schema validation, rollback strategies, and environment promotion (dev to staging to production).\n\nMonitor and optimise database performance: query analysis with EXPLAIN/EXPLAIN ANALYZE, index tuning, vacuum and autovacuum configuration, connection pool management (PgBouncer), and long-running query governance.\n\nOwn backup, recovery, and disaster recovery procedures: point-in-time recovery (PITR), WAL archiving, replication configuration (streaming and logical), and regular recovery testing.\n\nManage database security and access control: RBAC, row-level security (RLS), audit logging, secrets rotation via Azure Key Vault, and compliance with data protection policies.\n\nOperate and manage PostgreSQL on Azure: Azure Database for PostgreSQL Flexible Server configuration, high availability setup, read replicas, scaling operations, and cost governance.\n\nDefine and enforce database change management standards: peer review of migration scripts, naming conventions, anti-pattern detection, and pre-production validation gates.\n\nSupport Data Engineers and Backend Engineers with database design guidance, query optimisation advice, and hands-on troubleshooting of data access bottlenecks.\n\nManage database observability: dashboards and alerting for query performance, replication lag, connection saturation, bloat, and storage growth using Azure Monitor, pg_stat_* views, and Grafana.\n\nChampion Claude Code as a daily tool for writing and reviewing migration scripts, generating documentation, automating database maintenance tasks, and accelerating troubleshooting.\n\nRequired Experience & Skills\n6+ years of professional DBA experience with PostgreSQL as the primary platform, including deep operational knowledge in production environments.\n\nStrong database DevOps mindset: experience managing database artifacts as code, with version control, automated testing, and pipeline-driven delivery.\n\nHands-on experience with schema migration tooling: Flyway, Liquibase, sqitch, or equivalent - including branching strategies, baseline management, and rollback patterns.\n\nExpert-level PostgreSQL internals: MVCC, WAL, autovacuum, locking behaviour, query planner, index types (B-tree, GIN, GiST, BRIN), and connection management.\n\nExperience with PostgreSQL high availability and replication: streaming replication, Patroni or equivalent HA tooling, logical replication, and failover procedures.\n\nProduction experience with Azure Database for PostgreSQL: Flexible Server, HA configuration, PITR, read replicas, and Azure Monitor integration.\n\nProficiency in scripting for database automation: Python or Bash for maintenance scripts, migration utilities, audit tooling, and CI/CD integration.\n\nExperience with CI/CD pipelines in the context of database delivery: integrating migration tooling into GitHub Actions or equivalent, with environment promotion and rollback gates.\n\nStrong understanding of database security: RBAC, RLS, secrets management (Azure Key Vault), encryption at rest and in transit, and audit trail requirements.\n\nHands-on proficiency with Claude Code: using it daily for migration script authoring, query review, documentation generation, and operational automation.\n\nStrong communication skills: able to translate database constraints and risks clearly to Backend Engineers, Data Engineers, and product stakeholders.\n\nWhat we offer\nContract under Polish law: B2B or Umowa o Pracę\n\nBenefits such as private medical care, group insurance, Multisport card\n\nEnglish classes available\n\nHybrid work (at least 1 day/2 months on-site) in Warsaw (Mokotów)\n\nOpportunity to work with excellent professionals\n\nHigh standards of work and focus on the quality of code\n\nNew technologies in use\n\nContinuously learning and growth\n\nInternational team\n\nPinball, PlayStation & much more (on-site)\n\nJoin a growing team of dedicated professionals! We love to pass on the knowledge to grow excellence, speak our minds without playing politics, and just enjoy hanging around together. If you share our passions - we want to meet you!
