Overview
We are supporting a critical infrastructure organisation in their search for an experienced PostgreSQL Database Administrator (DBA) to support and enhance a distributed, cloud-native EDB PGD environment. This is a highly sensitive role requiring both BPSS and SC clearance prior to onboarding.
You’ll play a central role in maintaining the performance, availability, and reliability of a geographically distributed Postgres setup, running on Kubernetes and OpenShift clusters. The system is part of a wider, business-critical platform, demanding strong engineering focus and proactive operational excellence.
Key Responsibilities
Database Reliability & Performance
* Proactively identify and resolve performance bottlenecks
* Enhance database high availability using EDB Postgres Distributed (PGD)
* Troubleshoot issues and outages across a multi-cluster OpenShift setup
* Lead query tuning with tools like EXPLAIN, pg_stat_statements, and index optimization
* Manage capacity planning for CPU, memory, storage, and IOPS
Observability & Operations
* Improve observability tooling: manage metrics, dashboards, and alerts
* Monitor database health and respond to issues (replication lag, disk I/O, memory pressure)
* Manage and test backup and disaster recovery strategies (DR playbooks, failover in ORT)
* Optimize connection pooling to support high-volume applications
* Collaborate with DevOps and application squads during schema changes and deployments
Enhancements & Strategic Support
* Drive database enhancements aligned with platform upgrades and product evolution
* Ensure consistency and integrity across distributed database instances
* Support strategic data initiatives with deep PostgreSQL and Kubernetes expertise
Required Skills & Experience
* Strong hands‑on experience as a PostgreSQL DBA, ideally with EDB PGD or equivalent distributed Postgres setups
* Experience running Postgres in Kubernetes / OpenShift environments
* Deep knowledge of PostgreSQL internals, performance tuning, and replication strategies
* Proven ability to work in high‑availability, high‑security environments
* Familiarity with observability stacks and database performance tooling
* Strong troubleshooting skills and an automation‑first mindset
* UK‑based with valid BPSS and eligible for SC clearance (or already cleared)
What’s in It for You
* Opportunity to support a high‑profile, mission‑critical platform
* Influence modern database architecture in a multi‑cloud, containerised environment
* Contract with strong extension potential and excellent day rate
* Work alongside experienced engineering teams in a security‑conscious, forward‑thinking environment
