We're seeking a Lead Database Operations Engineer to become part of our team and drive a comprehensive Aurora MySQL remediation and optimization initiative spanning a tightly controlled production environment. This role takes ownership of schema modification, indexing, and cluster-isolation workstreams covering 36 databases, ensuring every change rolls out as an automated, fully reversible wave. All work is built natively on AWS: Aurora clusters function as Terraform-defined infrastructure, with Datadog and CloudWatch supplying the validation signals needed to greenlight each promotion
Responsibilities
- Clear out the outdated JSON column spanning 36 databases across six managed waves, confirming each wave's success before advancing to the next
- Develop automated reconciliation and rollback mechanisms ensuring every wave can be independently checked and completely undone if needed
- Eliminate unused indexes to reduce storage consumption and boost write throughput relative to an established baseline
- Take full ownership of Aurora MySQL cluster administration, including patch management, Blue/Green deployment execution, and parameter group configuration
- Separate two to three critical programs onto their own dedicated clusters to limit performance interference and reduce potential impact radius
- Analyze and improve query and index performance, documenting measurable gains achieved through each tuning cycle
- Set up and refine infrastructure-as-code deployments using Terraform and Terragrunt within GitHub CI/CD pipeline workflows
- Maintain and update database service listings within the Backstage developer portal and its service catalog
- Construct dashboards and alarm configurations in Datadog and CloudWatch, incorporating post-patch validation checks that control each wave's progression
- Function within PCI-regulated production access frameworks, documenting every change thoroughly to support audit requirements
Requirements
- Five-plus years of practical, hands-on experience in a comparable database operations position
- A minimum of one year spent leading and managing teams
- Hands-on background working with AWS Aurora to manage and fine-tune relational database clusters
- Strong track record using Amazon Web Services to set up and administer cloud-based infrastructure
- Background using Datadog to track system performance metrics and configure alerting mechanisms
- Deep MySQL expertise, including direct database administration experience covering patching, performance tuning, and cluster oversight
- Background applying Terraform to build and manage infrastructure through code
- Effective communication skills with working English fluency at B2 level or above, supporting clear grasp of business needs and their conversion into technical solutions
Nice to have
- Background using Amazon CloudWatch to monitor infrastructure metrics and set up alarm thresholds
- Exposure to Backstage for maintaining and publishing entries within a service catalog
- Awareness of PCI (Payment Card Industry) compliance standards as applied to production systems
- Background applying Terragrunt to coordinate and manage Terraform-based configurations
