About the Role
Allianz Technology SE is looking for a Senior Database Administrator to join our Technology & Infrastructure team. The primary focus of this role is PostgreSQL — both cloud-hosted (AWS and Azure) and on-premises deployments on Linux hosts. In addition, experience with MongoDB Atlas is valued and will play an increasing part in our database landscape.
You will own the design, operation, and continuous improvement of our relational and document database estates. Working closely with application development teams, cloud engineers, and security stakeholders, you will ensure our databases are performant, resilient, and compliant with Allianz and regulatory standards.
Key Responsibilities
PostgreSQL
-
Install, configure, and maintain PostgreSQL databases across cloud environments (AWS RDS/Aurora, Azure Database for PostgreSQL) and on-premises Linux hosts, covering version upgrades, patch management, and parameter tuning.
-
Monitor database health and performance using cloud-native tooling (CloudWatch, Azure Monitor) and third-party observability platforms; proactively identify and resolve bottlenecks in both cloud and on-prem deployments.
-
Optimise query performance through indexing strategies, query rewriting, and execution plan analysis (EXPLAIN / EXPLAIN ANALYZE).
-
Support data migrations using AWS Database Migration Service (DMS) or Azure Database Migration Service, including schema conversion, replication configuration, and cutover planning.
-
Manage and maintain PostgreSQL deployments on Linux hosts: OS-level tuning (kernel parameters, storage I/O), service management, and integration with enterprise monitoring and backup tooling.
MongoDB Atlas
-
Manage MongoDB Atlas clusters, including provisioning, scaling, and configuration of dedicated and shared-tier deployments across AWS, Azure, and GCP.
-
Administer Atlas backup and restore procedures: continuous cloud backups, snapshot scheduling, and point-in-time recovery.
-
Implement and maintain Atlas network security controls: VPC/VNet peering, private endpoints, IP access lists, and encryption at rest/in transit.
-
Monitor Atlas clusters and configure alerting: metrics thresholds, integration with external observability tools, and Performance Advisor recommendations.
-
Manage Atlas database users, roles, and X.509 certificate-based authentication in line with least-privilege principles.
