Group Lead -Mechanical Design

Larsen & Toubro

Provide end-to-end leadership for mechanical engineering and thermal systems of power electronics products and integrated systems, ensuring robust mechanical architecture, effective thermal management, environmental protection, manufacturability, and lifecycle reliability across high-power, high-density electrical platforms (Solar Inverters, BESS/PCS, EV Chargers, Electrolysers, and Industrial Power Electronics products.)

Key Responsibilities

Mechanical & Thermal Architecture Leadership
Define mechanical system architecture for:

Solar Inverters (String & Central)
BESS / PCS Cabinets & Containers
EV Chargers (AC, DC Fast, Ultra-Fast)
Electrolyser Power Supply Systems and other industrial PE products

Own thermal management strategy:

Natural & forced air cooling
Liquid cooling (cold plate, immersion where applicable)
Heat exchanger and airflow optimization

Define enclosure concepts, IP ratings, corrosion protection, and seismic/wind load compliance.
Product Engineering & Execution
Lead teams covering:

Mechanical Design & CAD
Thermal & CFD Engineering
Structural & Sheet-Metal Design
Packaging & Industrial Design

Establish mechanical design standards, guidelines, and review processes.
Drive power density improvements through optimized packaging.
Ensure design trade-offs between cost, thermal performance, reliability, acoustics, and serviceability.
Product Development Lifecycle Ownership
Own mechanical development across:

Requirements → Concept → Detailed Design → Prototype → Validation → Production

Implement V-Model / Stage-Gate / APQP processes.
Drive Design for Manufacturability (DFM), Design for Assembly (DFA), and Design for Serviceability (DFS).
Lead value engineering and cost-reduction initiatives.
Thermal, Reliability & Environmental Validation
Own thermal validation plans (steady-state, transient, derating analysis).
Drive CFD simulations and correlation with physical testing.
Ensure compliance with:

Temperature rise limits
Noise & vibration requirements
Environmental tests (IP, salt mist, humidity, dust)

Manufacturing, Quality & Field Support
Support NPI, pilot builds, and production ramp-up.
Drive mechanical failure analysis, field issue RCA, and corrective actions.
Work with supply chain on:

Vendor qualification
Localization & alternate sourcing
Tooling and fixture development

Improve yield, assembly time, and cost in production.
Cross-Functional & Business Engagement
Work closely with:

Electrical & Power Electronics Engineering
Systems & Controls
Manufacturing, Quality, and Supply Chain

Act as mechanical authority in customer and certification discussions.
Support pre-sales and customization efforts.
Build and mentor a high-performance mechanical engineering organization.
