Role Overview

The Company is seeking an experienced High Voltage Battery Design (400 V and above) & Development candidate to lead and support the design, development, validation, and integration of high-voltage lithium-ion battery systems for electric mobility and energy-storage applications. The ideal candidate will have more than 10 years of overall engineering experience, including 3–4 years of hands-on experience in the design and development of high-voltage lithium-ion battery packs and related systems. The role requires strong knowledge of battery pack architecture, mechanical and electrical design, thermal management, safety, validation, and production readiness.

Role Responsibilities -

· Lead the design and development of high-voltage lithium-ion battery packs and systems.

· Develop battery pack architecture, module layouts, busbars, HV junction boxes, contactors, fuses, connectors, and service-disconnect systems.

· Prepare and review 2D drawings, 3D CAD models, design specifications, and engineering documentation.

· Perform electrical, mechanical, thermal, and structural design assessments for battery systems.

· Support the design and integration of Battery Management System components, current sensors, voltage sensing, insulation monitoring, and high-voltage interlock loops.

· Conduct battery sizing, energy and power calculations, voltage-level selection, and cell/module configuration studies.

· Ensure designs comply with relevant high-voltage battery safety, performance, reliability, and regulatory requirements.

· Work closely with BMS, electrical, controls, thermal, simulation, manufacturing, testing, and supplier teams.

· Support Design for Manufacturing, Design for Assembly, serviceability, and cost optimization activities.

· Develop and review DFMEA, PFMEA, risk assessments, fault-tree analyses, and technical safety documentation.

· Define and execute design verification and validation plans.





· Analyze test results and support resolution of design, reliability, thermal, electrical, and safety issues.

· Lead engineering changes, root-cause investigations, corrective actions, and continuous improvement initiatives.

· Coordinate with suppliers on cell, module, enclosure, connector, busbar, cooling, and high-voltage component development.

· Support prototype builds, vehicle/system integration, production trials, and launch activities.

Provide technical guidance and mentoring to junior engineers.

Candidate Profile Requirements -

· Bachelor’s or Master’s degree in Electrical Engineering, Mechanical Engineering, Mechatronics, Automotive Engineering, Energy Systems, or a related discipline.

· 10+ years of total engineering experience with 3–4 years of hands-on experience in high-voltage lithium-ion battery design and development.

· Experience designing battery packs for electric vehicles, commercial vehicles, industrial equipment, energy storage, or similar applications.

· Robust understanding of lithium-ion battery cells, modules, pack architecture, and battery system performance.

· Practical knowledge of high-voltage systems, typically in the range of 400 V to 1000 V DC or equivalent.

· Experience with electrical schematics, wiring diagrams, cable routing, busbar design, grounding, insulation, creepage, and clearance requirements.

· Experience with mechanical battery pack design, enclosure development, sealing, crash protection, vibration, shock, and ingress protection.

· Knowledge of battery thermal management, including air cooling, liquid cooling, heat exchangers, cooling plates, and thermal interface materials.

· Proficiency in 3D CAD tools such as SolidWorks, or equivalent.

· Familiarity with engineering analysis and simulation tools.

· Experience with battery testing, validation, failure analysis, and production support.

· Strong understanding of engineering change management, configuration management, and technical documentation.

· Ability to work effectively in cross-functional and international engineering teams.
