Overview
Our client is seeking a Senior Database Administrator with deep expertise across Oracle, SQL Server, and MySQL, and proven experience supporting databases within Operational Technology (OT) environments. This is not a traditional IT DBA role. You will be working within safety-critical, highly regulated, and change-controlled industrial environments, supporting systems that directly impact SCADA, plant operations, manufacturing execution systems (MES), and real-time production. The focus is on stability, resilience, and security — where uptime, compliance, and safety are non-negotiable.
Key Responsibilities
- Database Administration & Operations

- Ensure 24/7 availability of mission-critical operational systems
- OT Systems Support
- Work closely with SCADA, control engineers, and plant operations teams
- Support databases integrated with PLCs, DCS, historians, and MES platforms
- Operate within restricted networks with strict change control and limited maintenance windows
- Troubleshoot issues impacting real-time operations and plant uptime
- Performance & Reliability
- Identify and resolve performance issues (wait events, deadlocks, slow queries)
- Implement high availability solutions including RAC, Data Guard, Always On, and Log Shipping
- Conduct proactive monitoring, tuning, and capacity planning
- Backup, Recovery & DR
- Manage RMAN, SQL Server backups, and MySQL backup strategies
- Execute point-in-time recovery and disaster recovery procedures
- Participate in resilience testing and DR exercises
- Security & Compliance
- Harden database environments in line with NIST, IEC 62443, ISO 27001
- Manage access controls, auditing, logging, and privilege management
- Apply patches within strict OT-approved schedules
- Documentation & Governance
- Produce detailed SOPs, architecture diagrams, and deployment guides
- Follow formal change management processes
- Maintain audit-ready documentation for regulatory inspections
Essential Skills & Experience
- Technical Expertise
- 7+ years hands-on DBA experience in production environments
- Strong administration experience with:
- Oracle 12c/19c
- Microsoft SQL Server 2016+
- MySQL (mandatory)
