## Description

As our PostgreSQL DBA, you will be the go-to engineer for everything data-layer: index and schema design on multi-terabyte tables, query optimization for application teams, connection pooling, upgrades, and migrations. Our PostgreSQL runs on Amazon Aurora - operating a large, fast-growing fleet consistently: turning one-off procedures into reliable automation, keeping dozens of clusters healthy at once, and helping developers use the database well. You'll split your time between a support rotation for incoming developer requests and longer-cycle reliability and automation projects.

In this role, you will also be responsible to:

 * Own day-to-day PostgreSQL operations across all production data centers: index creation on large/partitioned tables, query-plan analysis, schema reviews, data migrations.
 * Partner with application teams on data-model decisions - design, partitioning, retention, consolidation vs. standalone clusters - and push back with data when a design won't scale.
 * Operate and tune Aurora PostgreSQL: parameter groups, replicas, failover behavior, capacity planning.
 * Run and evolve our PgBouncer connection-pooling layer.
 * Turn manual runbooks into released, repeatable automation: seamless upgrade, switchover, database/user provisioning, grants management (Terraform + Ansible).
 * Drive incident response and RCAs for database-related issues, and land the follow-up actions.
 * Maintain and improve database observability (postgres_exporter, VictoriaMetrics dashboards and alerts).
 * Take part in the team's duty rotation handling developer requests, with protected focus time off-duty.
