Responsibilities

• Develop and own electrical designs for assigned subsystems within multi‑MW energy storage products, including battery systems, power conversion systems, medium‑voltage transformers, controls hardware, communication systems, auxiliary power, and safety equipment.
• Prepare and maintain technical documentation including design specifications, datasheets, interface documents, configuration limitations, and product performance metrics.
• Collaborate with mechanical, electrical, software, verification, testing, manufacturing, and product management teams to achieve program objectives.
• Support system integration activities by ensuring assigned subsystem designs are compatible with overall product architecture and meet functional requirements.
• Understand interactions between major BESS components and evaluate the impact of engineering changes on system performance, safety, reliability, and cost.
• Support development of installation manuals, operation manuals, maintenance documentation, and site design guides.
• Perform and review electrical studies including short circuit analysis, protection sizing, protection coordination, arc flash analysis and auxiliary load estimation.
• Evaluate applicable electrical standards, product safety requirements, and local codes to support compliance and certification activities.
• Work with electrical component suppliers to evaluate components, review technical data, and support component selection activities.
• Incorporate lessons learned and feedback from regional engineering, commissioning, manufacturing, and service teams into product improvements.
• Support product releases by preparing engineering documentation through Product Lifecycle Management (PLM) tools and coordinating with CAD drafting teams.
• Support prototype builds, hardware validation, test planning, execution, and issue resolution.
• Collaborate with systems engineers, component owners, program managers, and verification teams throughout the product development lifecycle.
• Independently execute engineering tasks for New Product Introduction (NPI) projects and support technical planning for assigned work packages.
• Participate in root cause analysis, corrective actions, DFMEA activities, and continuous product improvement initiatives.
• Protect intellectual property and follow engineering processes, quality standards, and export‑controlled technology requirements.
• Perform additional responsibilities as assigned.

Qualifications & Skills

• Bachelor or Master degree in Electrical Engineering (Full Time) or equivalent.
• 4‑7 years of proven experience in Electrical Power Systems Design in Renewables (Solar, Wind, Hydro, BESS), Power Generation, or related industries.
• Experience in New Product Development process and Systems Engineering, preferably in the Battery Energy Storage industry.
• Working knowledge of Battery Energy Storage System (BESS) design, including component selection such as breakers, fuses and relays for DC and AC circuits, understanding of system architecture, site layout, functional safety analyses, auxiliary load estimation and battery sizing/configuration management.
• Experience in the selection of electrical components and associated interfaces including Batteries, Inverters, Inverter‑Duty Transformers, BMS, EMS, Low‑Voltage AC/DC switchgear and cabling systems, ensuring compliance with IEC, NEC and IEEE design standards.
• Working knowledge of industry standards such as NFPA 70, IEC 60364, UL 9540, and IEC 62933.
• Should have experience preparing Power Flow Arrangements, Single Line Diagrams (SLD), and Control Schematics.
