Requirements

• 5+ years of hands-on operational PostgreSQL experience (DBA / database reliability role)
• Strong command of query plans, indexing strategy, and performance work on multi-TB tables
• Production experience with managed PostgreSQL (Aurora or RDS) and a clear-eyed view of its constraints
• Working proficiency with Terraform and Infrastructure-as-Code practices; comfortable in Linux
• Experience with connection pooling (PgBouncer or similar) in production
• Practical experience with logical replication, major-version upgrades, and low-downtime migration techniques

• Experience with cloud infrastructure (AWS preferred); strong incident-management and RCA skills

Nice to Haves

What You'll Be Doing

• 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
