PostgreSQL Database Administrator

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 a Recovery Time Objective (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. Qualifications ● Experience: 7–10 years as a production PostgreSQL DBA. ● Core Internals: Deep mastery of MVCC, WAL, and Query Planner behaviour. ● Ecosystem: Proficiency with pgBouncer, Patroni, and cloud-native database environments (AWS/Azure). ● DevOps Mindset: Strong Linux skills and experience with Prometheus/Grafana monitoring.
