Location: Remote

Reporting to Lead DevOps Engineer

The Purpose

Administer and maintain production PostgreSQL databases on Amazon RDS and Aurora across development, staging and production environments.

Monitor and tune database performance using Performance Insights, pg_stat_statements and EXPLAIN ANALYZE, covering indexing, vacuum and query optimisation.

Plan and execute major-version upgrades and configuration changes with minimal downtime using blue/green deployments and logical replication.

Own backup, restore and disaster recovery, including point-in-time recovery, cross-region snapshots and regular restore drills against agreed RTO and RPO targets.

Review schema migrations from application teams (Knex, TypeORM) and enforce zero-downtime change patterns such as concurrent index builds and expand/contract.

Manage database infrastructure as code using Terraform and Terragrunt, delivered through GitHub Actions pipelines.

Implement database security controls including least-privilege roles, encryption, credential rotation via AWS Secrets Manager and audit logging with pgAudit.

Manage connection pooling, high availability and failover using RDS Proxy or PgBouncer and Multi-AZ configurations.

Support the data and BI teams with read replicas, replication and secure connectivity into Amazon Redshift and ELT tooling.

Define database alerting and runbooks, and participate in an on-call rotation to maintain 24/7 reliability.

Track and optimise database spend, including instance sizing, storage and IOPS selection and reserved capacity.

Collaborate closely with backend (Node.js/NestJS), DevOps and data teams to deliver reliable, well-modelled data services.
