BESS System Engineer (Battery Energy Storage System-R&EI)
Summary
System-level engineer in Jabil's Renewable & Energy Infrastructure business, defining and integrating BESS (battery energy storage system) architecture and subsystem interfaces, selecting components, and transferring designs to Jabil manufacturing sites. Covers factory validation/testing (FAT), documentation, and compliance with UL 9540/9540A, IEEE 1547, and IEC standards.
This role is part of Jabil's Renewable & Energy Infrastructure (R&EI) business, supporting the design and manufacturing of BESS products for global customers.
The BESS System Engineer is responsible for defining, integrating, and supporting Battery Energy Storage System (BESS) solutions at the product and system level for manufacturing in multiple regions. This role focuses on overall system architecture, subsystem integration, and transfer of design to Jabil manufacturing sites, ensuring alignment with regional grid-interconnection and safety standards.
The engineer will ensure that the BESS design meets performance, safety, compliance, and manufacturability requirements in accordance with applicable industrial standards in different markets (e.g., UL/NFPA, IEC/IEEE), and will collaborate closely with global engineering teams, suppliers, and customers during the design and factory validation phases. The primary focus is on product and factory-level integration and testing, in close collaboration with customer technical teams as needed.
Success in this role means effectively enabling system-level design and factory implementation, while communicating clearly with global and customer teams.
【ESSENTIAL DUTIES AND RESPONSIBILITIES】
- Work with the System Architect and functional teams (Electrical, Mechanical, and Software) to define and refine the BESS system architecture and key subsystem interfaces.
- Develop and maintain system-level requirements, specifications, and interface definitions across all subsystems.
- Design Reviews, DFMEA, and Cross-functional Collaboration
- Collaborate closely with global teams, external design partners, suppliers, and manufacturing sites to evaluate system designs and technical proposals, including participation in design reviews and DFMEA activities to ensure alignment with performance, safety, and manufacturability requirements.
- System Analysis, Component Selection, and Documentation
- Coordinate and review system-level design analyses (e.g., power flow, fault behavior, efficiency, operating modes, grid behavior, integration constraints) with internal function teams and external design partners.
- Support selection and evaluation of key components (batteries, PCS, transformers, switchgear, fire suppression, thermal systems, protection devices).
- Develop and review engineering drawings and studies, including SLDs (single-line diagrams), wiring diagrams, layouts, communication interfaces, and protection studies.
- Prepare technical documentation, solution briefs, and system specifications for global teams and customer stakeholders.
- Factory Validation, Compliance, and Productization
- Plan and support factory-focused system validation (e.g., FAT), including functional testing, safety testing, and standards compliance (UL 9540/9540A, IEEE 1547, IEC standards).
- Support design transfer and build readiness for prototype, pilot, and production builds.
- Work with manufacturing sites to resolve integration issues and drive DFM/DFT and reliability improvements for BESS products.
- Risk Management and Continuous Improvement
- Identify technical risks throughout the project lifecycle and drive mitigation plans with cross-functional and cross-regional teams.
- Maintain awareness of ESS/BESS industry trends, standards, and supplier technologies, and share relevant insights with internal teams.
