You will join the IT Security team to maintain high system integrity for mega-scale battery storage solutions, overseeing OT infrastructure, cybersecurity, and cloud integration across live sites. Your work ensures stable, secure OT operations and supports real-time analytics and AI-driven maintenance.

Requirements

• Industrial Control Systems (ICS) SCADA Expertise in configuring and optimising ICS environments, including SCADA, HMIs, PLCs, RTUs, and IEDs for real‑time operations.
• Skilled in applying and interpreting industrial protocols - Modbus, DNP3, IEC 61850, and OPC/OPC‑UA—to ensure reliable device and system communication.
• Proficient in applying OT security frameworks (AESCSF, IEC 62443) to guide hardening, segmentation, and secure system architecture.
• Skilled in diagnosing faults across OT networks, control systems, data pipelines, and BESS subsystems using structured problem‑solving and root‑cause methods.
• Knowledge of OT–cloud integration patterns, including telemetry pipelines, secure connectivity, and cloud‑based monitoring and analytics.
• Experienced in coordinating technical validation and lifecycle activities with OEMs, service providers, and contractors across reviews and assessments.
• Proficient in producing clear, accurate technical documentation, including diagrams, procedures, system records, and operational artefacts.

Responsibilities

• Manage and maintain OT infrastructure—including SCADA, HMIs, BESS, gateways, and historians—while overseeing configuration, documentation, system health, automation, and lifecycle planning.
• Support secure, governed OT–cloud integration (Azure/AWS) with accurate, high‑quality data flows for real‑time analytics and AI‑driven maintenance.
• Apply OT cybersecurity and compliance practices across AESCSF/IEC‑62443, hardening, secure access, monitoring, vulnerability management, asset control, backups, and SOCI requirements.
• Maintain and troubleshoot OT system performance and communications across SCADA, RTUs, historians, and BESS subsystems while resolving incidents, supporting on‑call operations, and improving OT architectures and practices.
• Coordinate OT vendor support, technical reviews, compliance, lifecycle planning, Tier 2/3 assistance, and commissioning activities while reviewing documentation and deliverables.
