Position Summary

We are seeking a highly experienced Lead Mechanical Engineer specialising in Battery Energy Storage Systems (BESS) to join our growing Energy Storage Division. The successful candidate will own the end-to-end mechanical design, structural analysis, and certification of 20-foot ISO containerised battery enclosures and related infrastructure, from concept through commissioning. This is a senior individual-contributor and technical-leadership role that directly influences product architecture, manufacturing partners, and regulatory compliance strategy — including the full suite of relevant IEC and international standards.

Key Responsibilities

Enclosure & Container Design
Lead the full mechanical design lifecycle of 20-foot battery container/enclosure systems, including structural frames, base skids, wall panels, roofing, doors, and lifting lugs.
Develop and own 3D CAD models and detailed engineering drawings (GD&T;) for fabrication, using SolidWorks, CATIA, or equivalent parametric tools.
Define and manage BOM structures, part numbering,



and revision control in PLM/PDM systems.
Specify and select enclosure materials (steel, stainless, aluminium, composites) based on corrosion class, fire rating, and thermal requirements.
Design internal layout for battery rack integration, cable management, thermal management, and auxiliary equipment (HVAC, fire suppression, electrical panels).
Drive Design-for-Manufacture (DFM) and Design-for-Assembly (DFA) reviews with contract manufacturers.
Ensure container dimensional and structural interface compliance with ISO 668 and ISO 1496-1 (series 1 freight container specifications).
Structural Analysis & FEA
Perform and lead structural analysis of enclosure assemblies under seismic, wind, snow, dead, and live load combinations per applicable codes (IBC, ASCE 7, Eurocode EN 1993 as needed).
Conduct or oversee Finite Element Analysis (FEA) using ANSYS, Abaqus, or SolidWorks Simulation for stress, fatigue, buckling, and mo
