Database Administrator

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.

What Makes You a Fit

• Deep experience administering PostgreSQL 14+ in production, including MVCC, vacuum tuning, WAL, replication and lock behaviour.

• Strong hands-on knowledge of Amazon RDS and Aurora PostgreSQL, including parameter groups, Performance Insights, Enhanced Monitoring and blue/green deployments.

• Proven backup and recovery experience, including real restore exercises and cross-region recovery.

• Proficiency in Terraform and Git-based workflows for managing database infrastructure.

• Solid scripting skills in Python, Bash or SQL for automation, health checks and reporting.

• Strong understanding of schema design, query optimisation and indexing strategies for high-transaction workloads.

• Working knowledge of Redis/ElastiCache and MongoDB administration.

• Understanding of database security and compliance requirements (PCI DSS, GDPR) for customer and payment data.

• Comfortable operating in a multi-account AWS environment with SSO and CI/CD-driven deployments.

• Ability to write clear runbooks, post-mortems and change plans that other engineers can follow.

Preferred/Bonus Qualifications

• Background in iGaming, Sportsbook or Fintech platforms.

• Experience with Amazon Redshift or another columnar data warehouse, and ELT tools such as Airbyte or AWS Glue.

• Experience with PostgreSQL extensions and tooling such as pgAudit, pg_partman and pg_repack.

• Experience with observability tooling (Grafana, OpenTelemetry, CloudWatch) in high-traffic environments.

• Familiarity with Node.js ORMs and migration tooling (Knex, TypeORM, Prisma).

• Knowledge of event-driven architectures (Kafka, RabbitMQ) and change data capture (Debezium).
