Περιγραφή θέσης εργασίας

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.
  • Requirements:

  • 5+ years of proven experience as a Database Administrator or Database Engineer, with hands-on depth in PostgreSQL and MySQL 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.
  • Nice to have:

  • Production experience with ClickHouse, Redshift, MongoDB or Microsoft SQL Server.
  • Familiarity with Docker and Kubernetes in the context of database workloads.
  • Prior experience with financial services audit requirements or other regulated environments.
  • AWS certification (Database Specialty, Solutions Architect, or similar).
