Job description

What the role is

The key scope of work for the position is to provide operational support of Energy Management Systems which involves round the clock monitoring and control of electricity generators as well as the electricity and natural gas transmission networks. In addition, the position is also required to operate a Cybersecurity Operation Centre to monitor cybersecurity threats and manage Power Sector Critical Information Infrastructure incidents.

What you will be working on

Energy Management System (EMS) Operations & Supporting Infrastructure

• Provide operational and first-level technical support for the EMS to ensure the high availability and reliability of power system operations, including 24/7 monitoring and control of electricity generation, electricity transmission, and natural gas transmission networks. Operate and maintain EMS platforms, supporting Operational Technology (OT) systems, and associate OT/IT network and security infrastructure. Investigate and resolve technical issues to maintain continuous and reliable system performance.
• Support the development and enhancement of mission-critical EMS capabilities, including the integration of solar generation, energy storage systems, electricity imports, and other emerging energy resources.
• Maintain and support real-time power system applications, including state estimation, network and contingency analysis, short-circuit analysis, Automatic Generation Control (AGC), load and solar PV forecasting, telemetry systems, and dispatcher training simulators.
• Coordinate with licensees and stakeholders on the connection and integration of new generation facilities and transmission equipment, including updating and validating EMS databases to ensure alignment between system models, field equipment, and operational requirements.
• Support critical control-centre infrastructure, including uninterruptible power supply (UPS), fire protection, and physical access control systems, to ensure resilient and reliable operations.

Cybersecurity Monitoring & Incident Management

• Support the operation of the Cybersecurity Operations Centre (CSOC) to monitor and manage cybersecurity threats affecting power system operations and the Power Sector's CII.
• Analyse security alerts and anomalies, perform incident triage and investigation, and coordinate with relevant stakeholders and CII operators to contain, remediate, and resolve cybersecurity incidents.

Cybersecurity Risk Management

• Support the implementation of cybersecurity controls and mitigation measures to strengthen the security and resilience of EMS and related systems, in accordance with the Cybersecurity Act, applicable Codes of Practice, and other regulatory requirements.
• Support security reviews, risk assessments, and audits to identify vulnerabilities and security gaps, and implement remediation measures including system patching, audit recommendations, security hardening, and maintenance of cybersecurity documentation.

What we are looking for

• Strong interest in power system operations, EMS/SCADA, Operational Technology (OT), and cybersecurity, with a commitment to supporting critical infrastructure.
• Basic knowledge of computer systems and operating systems, including Linux/Unix and Windows.
• Familiarity with networking fundamentals, common protocols, troubleshooting, and network security concepts.
• Basic understanding of cybersecurity principles, including security monitoring, incident response, vulnerability management, and standards such as ISO/IEC 27001.
• Good analytical, problem-solving, communication, and teamwork skills, with a willingness to learn and work in a mission-critical operational environment.
