Responsibilities
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.
Requirements
Qualifications / Experience / Technical Skills
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.
Scripting ability (Bash, Python or GO) and an automation-first mindset.
Experience with cloud infrastructure (AWS preferred); strong incident-management and RCA skills.
Nice to Haves
Operational exposure to ClickHouse, OpenSearch, or Redis/Valkey, Neo4j.
Kubernetes fundamentals (our poolers, proxies, and exporters run on EKS).
Experience with Vault, ArgoCD, or GitOps workflows.
Comfort using AI coding assistants to accelerate routine analysis and tooling.
