Responsibilities

MySQL Operations & Administration

• Design and implement indexing strategies and approved schema changes.
• Tune MySQL/InnoDB parameters (buffer pool, redo logs, I/O, connections, temp tables).
• Identify and resolve locking issues, deadlocks, replication lag, and inefficient query patterns.

Availability, Backup & Disaster Recovery

• Design and operate backup strategies (logical/physical backups, binlogs, encryption where required).
• Execute and document regular restore tests to validate RPO/RTO objectives.

Security & Compliance

• Apply MySQL hardening and security standards (TLS in transit, encryption at rest where supported, restricted access).
• 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.
• Produce corrective and preventive actions for major incidents.
• Maintain operational documentation (backup/restore, failover, replication, performance issues).

Requirements

Technical Skills

• Strong MySQL administration experience (preferably 8.0+).
• Advanced SQL tuning, indexing, and execution plan analysis.
• Expert backup/restore and point-in-time recovery (mysqldump, mysqlpump, Percona XtraBackup or equivalent).
• 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).
• Automation/SRE mindset with scripting (Bash, Python, Perl).

Experience
