• Experience with Linux-based database environments, shell scripting, monitoring, and troubleshooting.

• Understanding of high-availability, downtime minimization, RPO/RTO, and production change management.

• Good communication skills and ability to work with DevOps, backend engineers, functional consultants, and project stakeholders.

Nice-to-have skills:

• Experience with Prometheus, Grafana, Alertmanager, Loki, or similar observability tools.

• Familiarity with data migration, ETL, data validation, or reconciliation processes.

Responsibilities:

• Run and analyze MySQL upgrade compatibility checks, identify blockers, and prepare remediation plans.

• Review database configuration, schemas, indexes, stored routines, replication setup, users, grants, and backup strategy.

• Design and support migration approaches such as logical dump/restore, staged upgrade, replica-based migration, or blue-green cutover.

• Prepare migration runbooks, validation checklists, rollback plans, and production cutover procedures.

• Support performance testing, query plan analysis, and post-migration tuning.
