You will upgrade and migrate across engines (PostgreSQL, MySQL, Redshift, ClickHouse, DynamoDB) with minimal production impact, ensure backups, and enforce robust security and Linux

Qualifications

• 5+ years of proven experience as a Database Administrator or Database Engineer in production environments.
• Solid Terraform experience - you've written and maintained IaC
• Working knowledge of Ansible for configuration management and deployment automation
• Strong Linux system administration skills, including performance tuning and troubleshooting
• Experience designing and operating high-availability solutions - failover, replication, load balancing, DNS management
• Familiarity with Prometheus and Grafana or comparable monitoring tools
• Scripting ability in Bash and/or Python for automation and operational tasks
• Understanding of CI/CD pipelines and how database changes fit into a deployment workflow
• Comfort working in a regulated financial services environment, where access control, encryption, and audit trails are non-negotiable

Responsibilities

• Own the provisioning, configuration, and ongoing maintenance of PostgreSQL and MySQL instances across AWS RDS and on-premises, ensuring they meet uptime and performance targets
• Design and implement automated failover solutions, load balancing configurations, and DNS management strategies to keep databases accessible under failure conditions
• Write and maintain Terraform code to provision and manage database infrastructure - clusters, instances, storage, parameter groups, security groups - with consistency across environments
• Build and manage Ansible playbooks and roles for database deployments, configuration changes, and patching cycles
• Monitor, alert, and tune - using Prometheus and Grafana - to catch performance degradation before it becomes an incident
• Plan and execute database upgrades and migrations, including cross-version and cross-engine work (PostgreSQL, MySQL, Redshift, ClickHouse, DynamoDB), with minimal impact to production
• Manage backup, restore, and recovery processes; test them regularly so they work when it matters
• Harden database security through access controls, encryption at rest and in transit, and periodic audits
• Maintain and improve underlying Linux systems hosting the databases, including security hardening and performance tuning
• Document configurations, runbooks, and disaster recovery plans; participate in on-call rotation
