Hardware System Sizing Engineer - BEV

Hardware System Sizing Engineer – BEV/xHEV Propulsion Systems

Experience: 5-12 yrs

Location: Pune

Department: Electrified Propulsion Systems – Hardware Architecture

Role Summary:

Key Responsibilities

• Lead hardware sizing activities for propulsion system components including e-motors, inverters, battery packs, and cooling modules
• Translate vehicle-level performance targets into component-level sizing and specification requirements
• Perform trade-off studies and parametric analysis to balance performance, cost, weight, and thermal constraints
• Develop and maintain sizing models using tools such as MATLAB/Simulink, Excel-based calculators, or proprietary platforms
• Collaborate with system architects, thermal engineers, and controls teams to ensure optimal system-level integration
• Support benchmarking and technology roadmap activities to inform sizing strategies
• Contribute to design reviews, DFMEAs, and validation planning for hardware components
• Document sizing rationale and maintain traceability to system requirements and vehicle targets

Qualifications & Skills

• Bachelor’s degree in mechanical engineering or related field (master’s preferred)
• Strong understanding of electromechanical systems, thermodynamics, and energy conversion
• 4 + years for Powertrain domain experience much required. Also experience in sizing propulsion components for automotive.
• Proficiency in modelling and simulation tools (e.g., MATLAB/Simulink, GT-Suite, Excel VBA)
• Familiarity with BEV/xHEV architectures and performance requirements
• Knowledge of automotive development processes and system engineering principles
• Strong analytical, communication, and documentation skills

Preferred Experience

• Prior experience in electrified powertrain development or system architecture
• Exposure to battery pack sizing, inverter thermal limits, and motor torque-speed mapping
• Understanding of vehicle-level drive cycles and energy consumption modelling
• Experience with requirement management tools (e.g RMDV , TRM, XRAY)
