We are looking for a Database Reliability Engineer to join our team. This is not a traditional DBA role — you are a DevOps engineer who happens to have deep SQL and database knowledge. You think in code, manage infrastructure via Terraform, and treat database provisioning, patching, and performance as an engineering problem — not a manual task.

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

#LI-Hybrid

You Have:

Essential

• Strong SQL — complex queries, performance tuning, indexing, EXPLAIN plans

• AWS — RDS Aurora, Secrets Manager, IAM, CloudWatch, VPC networking for databases, KMS encryption

• Terraform — writing and maintaining modules, state management, remote backends, version pinning

• Scripting — Python or Bash for automation, operational tooling, and migration scripts

• CI/CD — GitLab CI or equivalent; using pipelines for infrastructure changes and database migrations

• Observability — experience with Datadog, CloudWatch, or Prometheus/Grafana for database metrics and alerting

• Linux — comfortable with system-level troubleshooting in production environments

Good to Have

• PostgreSQL — deep knowledge: vacuuming, autovacuum tuning, replication (logical/streaming), pg_stat views, extensions

• PgBouncer or RDS Proxy — connection pooling configuration and tuning

• Kubernetes — understanding how workloads connect to databases, sidecar patterns, secrets injection

• Database migrations — zero-downtime schema migrations with tools like Flyway, Liquibase, or custom scripted approaches

• Financial services or regulated environments — familiarity with audit logging, data residency requirements, PCI DSS / SOC 2 controls

• AWS Aurora Global Database — cross-region replication, disaster recovery patterns

What We Don't Want

To be clear about the profile we're not looking for:

• Traditional Oracle/MSSQL DBA focused on GUI-based administration

• Engineers who manage databases manually rather than through code

• Candidates whose primary experience is "advising" rather than building and operating

You Will Thrive Here If

• You've written Terraform to provision an RDS cluster, not just clicked through the console

• You've debugged a production slow query using EXPLAIN ANALYZE and fixed it

• You think "how do I automate this" before "how do I do this manually"

• You're comfortable being on-call and leading database incident response

• You want to build platform capabilities other engineers self-serve, rather than being a bottleneck
