About the Role As a Senior DBA, you will own the end-to-end lifecycle of our PostgreSQL clusters. This is a hands-on role focused on operating at scale optimizing complex queries, managing multi-terabyte partitioned tables, and ensuring our reporting workloads thrive without impacting production stability.
Key Responsibilities
- Cluster Orchestration: Design and manage high-availability (HA) PostgreSQL clusters (Single-node, Patroni, or managed cloud) across all environments.
- Performance & Tuning: Proactively monitor and resolve bottlenecks, including vacuum/autovacuum tuning, index bloat, and connection management.
- Data Lifecycle & Partitioning: Implement advanced partitioning strategies (Range, List, Hash) and automated archival policies to maintain performance as datasets grow.
- Resiliency & Security: Own the backup/DR strategy (PITR, pgBackRest), execute zero-downtime upgrades, and enforce RBAC and encryption standards.
- Analytics Support: Optimize read-replicas and materialized views to enable high-performance BI reporting (Tableau/Power BI) without compromising OLTP speed.
- Automation: Utilize Infrastructure as Code (Terraform) and scripting (Python/Shell) to automate provisioning and maintenance.
- High Availability & Disaster Recovery: Design and orchestrate automated failover (Patroni/Cloud HA) to maintain RTO of <15 minutes and near-zero data loss (RPO).
- Financial Integrity & Compliance: Enforce SOC2/GDPR standards by implementing granular audit logging, encryption, and automated PII masking across all environments.
- Data Lifecycle & Archiving: Architect and execute data retention policies that move aged trade data to lower-cost storage tiers without sacrificing accessibility for BI or regulatory audits.
