Senior Database Reliability Engineer I - Germany/Austria/UK

Responsibilities

• Own the reliability, performance, and scalability of our PostgreSQL platform (primarily Amazon Aurora): query and index strategy, execution plans, configuration tuning, and capacity planning, with particular attention to hot multi-tenant read paths.
• Lead zero-downtime version upgrades and schema migrations at scale, including diagnosing and preventing plan regressions across Aurora major versions.
• Own the operational health of the platform: vacuum strategy and bloat, long-running transactions and wraparound risk, connection management and pooling (including RDS Proxy), lock contention, and logical replication and slot hygiene.
• Own backup, restore, and disaster recovery end-to-end, including rehearsed restore drills and the access, encryption, and auditing controls our compliance obligations require.
• Deliver infrastructure and automation as a full member of the Infrastructure team, using Terraform and cloud-native tooling on AWS, and contribute to CI/CD pipelines including the safe automated handling of database changes.
• Build and maintain monitoring, alerting, and observability for database and platform systems (e.g. pg_stat_statements, Prometheus exporters, Grafana, Datadog, OpenTelemetry) so problems surface before customers feel them.
