Engineer III

Overview

The BESS Technical Project Manager drives execution of Nextpower's HD5AC V0 and V1 AC block development programs, serving as the China-based link between suppliers and the US engineering team.

What you'll do

• Maintain the integrated V0 and V1 program plan, including milestones, dependencies, supplier commitments, risks, and recovery actions from design through production readiness.
• Drive day-to-day execution with China-based suppliers through regular meetings and factory visits; verify progress against evidence, challenge missed commitments, and follow actions through closure.
• Coordinate V0 supplier-led integration and V1 interfaces supporting US final integration, aligning battery, enclosure, BMS, and power conversion system (PCS) deliverables.
• Participate actively in technical reviews; clarify requirements, identify interface gaps, document decisions, and route design questions to the responsible engineering owners.
• Coordinate prototype builds and test readiness, ensuring drawings, materials, software versions, equipment, personnel, and approved procedures are available when needed.
• Support factory acceptance and integration testing with engineering and quality teams; witness approved tests, collect results and logs, track defects, and coordinate corrective actions and retesting.
• Coordinate supplier inputs, samples, and documentation for UL 9540 evaluation and other required qualification activities with the engineering and certification teams.
• Maintain action, issue, and change logs; communicate concise status updates and escalate schedule, quality, or technical risks with proposed solutions and clear decisions needed.
• Support production handoffs by confirming release documentation, open-item closure, and supplier readiness with engineering, quality, supply chain, and operations.
• Handle budget and cost tracking, shipping and customs to US sites, change control with cost impact, site delivery and commissioning, status reports to customers, and visits to customer sites.

What you'll need

• Strong working knowledge of utility-scale BESS architecture, battery systems, BMS, PCS, enclosures, thermal management, and electrical and communications interfaces.
• Ability to read single-line diagrams, electrical schematics, mechanical layouts, specifications, and test reports and contribute meaningfully to technical discussions.
• Proven ability to manage schedules, dependencies, risks, and multiple suppliers, with proactive follow-through, sound judgment, and a strong sense of ownership.
• Practical understanding of prototype builds, factory testing, troubleshooting coordination, root-cause analysis, and corrective-action verification.
• Familiarity with BESS safety and certification requirements, including UL 9540, and the discipline to work within approved test procedures and engineering authority.
• Professional proficiency in Mandarin Chinese and English, with clear written reporting and the ability to coordinate technical teams across cultures and time zones.
• Bachelor's degree in Electrical Engineering, Mechanical Engineering, Energy Engineering, or a related technical field.
• Minimum 5 years of experience in BESS, including technical project management, supplier coordination, system integration, or product development.

Nice to have

• Demonstrated experience working directly with China-based BESS suppliers and supporting prototype builds or factory testing.
• Experience coordinating with US engineering teams.

Details

• Based in China, with regular travel to supplier factories and test facilities; occasional international travel may be required.
• Work includes office and factory environments, standing and walking during inspections and testing, and use of required personal protective equipment.
• Flexibility to participate in scheduled meetings with US teams across time zones is required.
