Job Summary

The lead structural simulation engineer will lead structural analysis and simulation activities for Battery Energy Storage System (BESS) products and other large similar structure products. This role is responsible for developing and executing finite element analysis strategies to evaluate structural integrity under variable conditions. The position will partner closely with mechanical design, system architect, thermal, electrical, safety, manufacturing, quality, and customer teams to optimize structure design robustness, manufacturability, cost, reliability, and compliance with applicable industry requirements. The role requires strong technical depth in structural mechanics and FEA, practical understanding of battery enclosure architecture, and the ability to guide cross-functional teams, mentor engineers, and drive simulation best practices across all structure design programs.

Location:

This role will be based at Jabil's Huangpu office in Guangzhou, Guangdong Province, China.

Essential Duties and Responsibilities

• Lead structural simulation activities for BESS products and similar products, including battery cabinets, containerized enclosures, battery racks, module trays, frames, doors, lifting points, and anchoring interfaces.
• Develop and execute finite element analysis models and simulation plans for static strength, stiffness, vibration, shock, transportation, lifting, seismic, wind-load, thermal-stress, fatigue, and durability conditions.
• Evaluate product structural risks related to mass distribution, rack stiffness, enclosure deflection, door sealing, HVAC mounting, cable/busbar support, shipping, installation, and long-term field reliability.
• Partner with mechanical design, system architect, thermal, electrical, test, manufacturing, quality, program, supplier, and customer teams to define requirements, acceptance criteria, validation plans, and design improvements.
• Correlate simulation results with physical test data and provide clear technical recommendations to improve product robustness, manufacturability, cost, serviceability, and compliance.
• Prepare and present simulation reports, margin assessments, technical risk evaluations, and design recommendations to internal stakeholders, customers, suppliers, and leadership teams.
• Establish simulation best practices, templates, workflows, material libraries, and validation methods to improve consistency, efficiency, and engineering quality across all design programs.
• Mentor simulation engineers, review technical work, and support development of structural simulation capability within the team.
• May perform other duties and responsibilities as assigned.
