  • Execute and document regular restore tests to validate RPO/RTO objectives.
    • Security & Compliance

  • Manage patching and upgrades with risk/impact assessment and change planning.
  • Support audits and compliance activities (access reviews, logging, evidence collection).
    • Monitoring & Incident Management
  • Implement and maintain monitoring and alerting (e.g. PMM, Prometheus/Grafana).
  • Define alert thresholds and reduce alert noise.
  • Provide incident triage, resolution, and root cause analysis within agreed SLAs.

  • Maintain operational documentation (backup/restore, failover, replication, performance issues).

    • Required Skills & Experience

  • Solid Linux fundamentals (CPU, memory, I/O, filesystems, networking).
  • Database security best practices (TLS, privilege management, auditing, secure configs).
  • Knowledge of at least one additional DB technology (PostgreSQL, Microsoft SQL Server).
