Capability Development

• AI-enabled diagnostics, and operational performance matters.
• Provide mentorship to strengthen technical competency in ESS systems, battery behaviour, and data-driven/AI-assisted performance engineering.
• Support regional Markets by contributing to ESS-focused technical training and capabilitybuilding programs, including uplift in digital analytics and the use of AI-powered performance tools.
• Lead and coach ESS Performance Engineers, providing guidance on liability, optimization,

Governance & Standards

• (SoC) behavior, degradation patterns, charge–discharge cycles, thermal management, and safety indicators —using both conventional analysis and AI-driven insights.
• Drive implementation of performance KPIs and coordinate ESS performance improvement programs across global Markets.
• Establish, maintain, and continuously refine technologyspecific performance benchmarks for ESS assets.
• Support the standardization of ESS monitoring dashboards, analytics platforms, and AI-enhanced reporting formats to improve visibility and early-warning capabilities.
• Provide guidance to Markets to ensure consistent adoption of corporate ESS standards, safety protocols, and operational governance frameworks.
• Oversee ESS operational performance metrics, including State of Health (SoH), State of Charge

Business Support

• Identify performance deviations, efficiency losses, abnormal cycling behaviour, and early signs of degradation across ESS assets using both engineering analysis and AI anomalydetection techniques.
• Conduct rootcause investigations and recommend actionable improvement plans, leveraging data science and predictive analytics where relevant.
• Analyze BMS, EMS, and SCADA data trends to detect emerging risks and recommend preventive measures, including the use of AIbased condition monitoring models.
• Lead ESS performance enhancement initiatives by applying global best practices, digital tools, and AIenabled optimization methodologies.
• Collaborate with Markets and corporate teams on crossfunctional performance enhancement, lifecycle improvement, and digital transformation projects.
• Conduct Level 2 (L2) audits to ensure compliance with project delivery, asset performance standards, and O&M processes.
• Support the evaluation of emerging ESS technologies—including LFP/NMC chemistries, flow batteries, hybrid systems, advanced BMS/EMS solutions, and AIdriven control or optimization platforms.

Qualifications, Skills & Experience

• Excellent communication skills, with the ability to explain technical ESS concepts clearly.
• Strong analytical capability with experience in handling battery and system-level datasets.
• Minimum 5 years in ESS engineering, renewable energy operations, power systems, or related energy sectors.
• Experience in ESS operations, BMS/EMS architecture, degradation modelling or power system integration is ideal.
• Familiarity with grid-forming (GFM) BESS application
• Demonstrated experience in deploying Battery Energy Storage Systems (BESS) for large Commercial & Industrial (C&I) facilities.
• Familiarity with applicable grid codes, interconnection standards, and utility requirements related to BESS deployment.
• Experience with HMA, HAZOP, FMEA, or root-cause analysis will be a plus.
• Degree in Electrical Engineering, Power Systems, Energy Storage or relevant engineering fields.
• Proactive, resourceful and strong in execution and troubleshooting.
• Occasional travel required.
• Proficient in Microsoft Office; experience with EMS/BMS platforms, Power BI, Python/MATLAB, or power system modelling tools is a plus.
