2. Customer Technical Communication & Requirements Clarification

• Act as the technical interface during project execution, working with customers, EPC contractors, and design consultants under the overall coordination of the Project Manager (PM).
• Independently organize and lead technical clarification meetings in English, translating customer requirements into clear, actionable technical inputs for internal engineering teams.
• Lead customer-facing explanations and clarifications regarding technical solutions, system limitations, and issue resolution outcomes.

3. System Integration & Technical Interface Coordination

• Coordinate technical interfaces involving battery systems, Power Conversion Systems (PCS), Energy Management Systems (EMS), and associated electrical distribution and monitoring systems.
• Drive the clarification and confirmation of electrical connections, auxiliary power supply, communication topology, control logic, and interface requirements.
• Identify technical gaps and integration issues between equipment and between equipment and the overall power plant, coordinating relevant parties to agree on implementable solutions and obtain customer confirmation.

4. Internal & Supplier Technical Coordination

• Work closely with internal technical support, R&D, product, and project delivery teams, as well as external PCS, EMS, and other equipment suppliers.
• Break down customer requirements and technical issues into specific actions, clarify responsibilities and deadlines, and organize technical discussions where necessary.
• Track progress, coordinate feedback, and drive technical issues toward practical solutions and timely closure.

5. Technical Risk & Change Management

• Identify configuration adjustments, interface changes, and additional technical requirements arising during project execution.
• Coordinate cross-functional assessments of their impact on system performance, reliability, scope of supply, delivery schedules, and O&M.
• Support the PM in change assessment and confirmation, maintaining clear records of technical decisions, changes, and customer communications.

6. Testing & On-site Implementation Support

• Provide technical support during Factory Acceptance Tests (FAT), on-site installation, commissioning, and project acceptance.
• Clarify design, configuration, and interface requirements throughout testing and implementation.
• Conduct initial assessments of technical issues reported on-site, coordinate with commissioning, O&M, and R&D teams, and follow up on corrective actions and verification until closure.

Requirements

1. Education

• Bachelor's degree or above in Electrical Engineering, Power Electronics, Power Systems, Automation, Telecommunications, or a related engineering discipline.
• At least 3 years of relevant technical experience in battery energy storage, photovoltaic inverters, power systems, industrial automation, or related fields.
• Practical experience in project implementation, system integration, engineering design, technical delivery, or commissioning.
• Hands-on experience in the end-to-end execution of BESS or PV-plus-storage projects is a strong advantage.

3. Technical Knowledge

• Solid understanding of BESS architecture, major components, and system operating principles.
• Familiarity with the technical interfaces and control relationships among battery systems, Battery Management Systems (BMS), PCS, and EMS.
• Practical engineering knowledge of electrical systems, power distribution, or industrial communications, with the ability to identify key system integration issues.

4. Engineering Drawings & Requirements Analysis

• Ability to read and interpret electrical single-line diagrams, wiring and connection drawings, communication topologies, and technical interface documents.
• Ability to analyze customer requirements, identify scope-of-supply boundaries, missing information, and potential technical conflicts, and translate findings into actionable internal tasks and clarification items.
