You will own the database infrastructure layer across our AWS environments: provisioning scaling observability and reliability all through Infrastructure-as-Code. Our current estate includes SQL Server running on Windows EC2 instances. You will partner with application teams to ensure databases are correctly provisioned optimised and monitored without becoming a gatekeeper.

You Will:

• Provision and manage AWS RDS instances entirely through Terraform parameter groups subnet groups IAM authentication secrets rotation multi-AZ and read replicas

• Own database reliability design runbooks define SLOs set up alerting on slow queries connection pool saturation replication lag and disk growth

• Automate database operations schema migrations backup validation failover drills and patching via CI/CD pipelines

• Improve performance work with development teams on EXPLAIN ANALYZE query tuning indexing strategies and connection pooling (PgBouncer/RDS Proxy)

• Secure the data layer enforce encryption at rest/in transit IAM database authentication credential rotation via AWS Secrets Manager and least-privilege access patterns

• Contribute to the platform build reusable Terraform modules for database provisioning that application teams self-serve from the platform

• Participate in on-call rotation respond to database incidents drive RCAs and implement permanent fixes to prevent recurrence
