• Provide technical support during customer meetings, pre-sales discussions, solution presentations, and business case development.
• Resolve technical queries, troubleshoot system performance issues, and recommend performance optimization strategies.
• Conduct technical training for internal teams, EPC partners, customers, and service engineers.
• Support Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), commissioning, and project handover activities.
• Ensure compliance with applicable IEC, IEEE, UL, and other relevant electrical and renewable energy standards.

Required Skills

• Strong understanding of Battery Energy Storage Systems (BESS) architecture and components, including Battery Packs, Battery Management Systems (BMS), Power Conversion Systems (PCS), Energy Management Systems (EMS), Transformers, and Switchgear.
• Hands‑on experience in BESS sizing, electrical system design, and renewable energy integration.
• Expertise in transformer sizing, specification, and selection for grid‑connected renewable energy projects.
• Experience with Solar PV systems, hybrid Solar + BESS projects, site feasibility studies, and grid integration.
• Strong knowledge of load profile analysis, energy modeling, lifecycle cost analysis, and system performance optimization.
• Familiarity with electrical protection systems, HV/LV distribution systems, and utility interconnection requirements.
• Ability to interpret electrical schematics, Single Line Diagrams (SLDs), and engineering drawings.
• Experience in tender documentation, compliance evaluation, and technical proposal preparation.
• Excellent analytical, communication, stakeholder management, and problem‑solving skills.
• Proficiency in Microsoft Office tools (Excel, PowerPoint, Word) and AI productivity tools.

Preferred Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Power Systems, Energy Systems, or a related discipline.
• Experience with utility‑scale Battery Energy Storage Systems (BESS) and Solar + Storage projects.
• Knowledge of SCADA, EMS, remote monitoring, and data acquisition systems.
• Exposure to renewable energy regulations, international standards, and grid code requirements.
• Experience working with EPC contractors, utility companies, and renewable energy developers.

What We Offer

• Opportunity to work on large‑scale Battery Energy Storage System (BESS) and renewable energy projects.
