Senior Database Administrator- Remote near Alpharetta, GA

About The Role

OEC is in the middle of a multi-year journey to modernize our infrastructure and applications, migrating hundreds of services across dozens of engineering teams to AWS. As Senior Database Administrator, you will play a critical, hands-on leadership role in this transformation — owning the evolution of OEC’s database estate from legacy infrastructure to AWS-managed, cloud-native database services.

You will serve as OEC’s principal technical lead on database engineering — setting platform direction, driving migrations to Amazon RDS for SQL Server and Aurora PostgreSQL, and partnering with application engineering, DevOps, security, and cloud infrastructure teams to build a scalable, resilient, and secure AWS-native database operating model.

What You'll Do

• Own the migration of OEC’s database workloads to AWS managed services, with a primary focus on Amazon RDS for SQL Server and Aurora PostgreSQL as OEC’s target-state platforms; establish cloud-native standards for provisioning, scaling, and operations that eliminate manual overhead.
• Plan and execute database migrations to AWS using DMS and SCT; own the technical delivery of lift-and-shift and re-platform migrations and ensure each wave is sequenced, validated, and consistent with OEC’s transformation roadmap.
• Architect and operate AWS managed database environments with multi-AZ high availability, automated failover, RDS Proxy, and AWS Backup at their core; define the patterns and standards that will serve as OEC’s target-state database operating model.
• Implement and maintain database infrastructure as code using Terraform; define IaC standards for AWS managed service provisioning, parameter configuration, and lifecycle management, and integrate them into CI/CD pipelines.
• Lead cross-functional incident response and formal root cause analysis, coordinating across application, infrastructure, and cloud engineering teams to drive fast resolution and durable prevention.
• Manage database systems for resiliency, scalability, performance, and availability through cloud-native AWS services, proactive monitoring, and continuous optimization aligned with OEC’s service level objectives; must be proficient in AWS observability tooling (CloudWatch, RDS Performance Insights, DevOps Guru, Cost Explorer) and platforms such as Datadog.
• Enforce data governance and security using AWS Secrets Manager, IAM database authentication, KMS encryption, VPC isolation, and automated backup and retention policies in alignment with OEC’s data stewardship standards.
• Mentor and coach junior and mid-level DBAs on cloud-first AWS patterns; foster a collaborative, learning-oriented team culture and actively shape OEC’s database engineering practices.
