•    Ensure 24/7 availability for critical OT applications with minimal downtime.

•    Work with control engineers, SCADA teams, and plant operations to support databases tied to PLCs, DCS, historians, MES, and plant automation systems.
•    Support systems with limited maintenance windows, strict change control, and long lifecycle support requirements.
•    Troubleshoot database issues affecting real time operations, ensuring safety and plant uptime.


Performance & Reliability
•    Identify and resolve performance bottlenecks (ORA wait events, deadlocks, slow queries).
•    Implement high availability configurations (RAC, Always On, Log Shipping, Data Guard).
•    Conduct capacity planning to support long-term OT system stability.
Backup, Recovery, and Disaster Preparedness
•    Implement and manage RMAN, SQL backups, recovery strategies, point in time restores.
•    Ensure alignment with OT disaster recovery plans and regulatory compliance.
•    Participate in DR testing and resilience exercises.
Security & Compliance
•    Maintain hardened database configurations following OT cyber security frameworks (NIST, IEC 62443, ISO 27001).
•    Control access, privilege management, auditing, and logging.
•    Ensure patching is done in accordance with strict OT patch cycles and downtime rules.
Documentation & Change Management
•    Create detailed database architecture diagrams, SOPs, and deployment guides.
•    Follow stringent OT change management procedures for upgrades and modifications.
•    Maintain audit ready documentation for compliance and regulatory inspections.
