We are hiring a Senior PostgreSQL DBA to join our Infrastructure Storage team and own the health, performance, and day-to-day operations of the database fleet behind Workato's enterprise automation platform. You will work across dozens of Aurora PostgreSQL clusters in production data centers worldwide – a fleet that is about to double – as part of a small, flexible team of infrastructure specialists.

Role Overview

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.

Responsibilities

- 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

- 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 Have

- 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.
