Sankha Dey

Electrical and Electronics Engineer with 4+ years of experience across 3 production BEV programs, delivering verifiable impact: 70% field failure elimination, 20% BOM cost reduction, and 14 published patents. Specialized in HV E/E architecture, powertrain ECU control strategies, and system-level engineering across Tier-1 OEM environments. Proficient in full V-cycle development: from system requirements definition and architecture design through hardware-software integration, HIL/LabCar validation, and after-sales diagnostic support.

Experienced collaborating with international cross-functional teams across mechanical, software, manufacturing, and supplier domains.

R&D Engineer - BEV E/E Architecture at TATA Technologies Ltd. | Advance Engineering Department, Tata Motors (2024-09 – Present)

• Architect E/E systems across 3 OEM BEV programs: system requirements definition, wiring harness optimization, ECU integration, and full after-sales lifecycle ownership.
• Developed ECU control algorithm eliminating 70% of CCS2 charging actuator failures across production fleet - validated via HIL/LabCar DVP testing with cross-functional software, hardware and validation teams. IP Award: Most Impactful IP - Tata Motors
• Designed 6-in-1 PECU (E-Drive + OBC + DC/DC + PDU + Thermal): 15% wiring harness reduction, 12% thermal efficiency gain, full EMI/EMC certification. Best Project Award - Harrier EV, Tata Motors
• Reduced field failures 20-25% across programs via structured RCA, Tier-1 supplier corrective actions, and systematic after-sales closure.
• Executed HIL/LabCar validation and fault injection across DVP test plans; compressed validation cycle by 30% through DTC standardization across 4 ECU domains.
• Led Harrier EV CFT and QRT: coordinated 4 cross-functional teams, resolved 15+ critical HV/LV field issues, achieved zero-defect EOL dispatch.

R&D Engineer - Product Development at Revamp Moto Pvt. Ltd. (2022-07 – 2024-09)

• Delivered 2 commercial BEV platforms (Mitra L3-BEV, Buddie L1-BEV) from concept to SOP in 18 months - deployed across 5+ fleet operators and 5000+ vehicles.
• Redesigned E/E architecture and wiring harness for Buddie: 20% BOM cost reduction and 60% field failure reduction through systemic topology optimization.
• Architected Mitra L3-BEV swappable battery platform: embedded BMS, CAN network, OTA diagnostics, telematics and fleet management integration.
• Engineered V2L bi-directional power system (3.3 kW) with HV safety interlocks and intelligent load management - deployed across 2 product lines.
• Drove 30% B2B adoption growth through targeted enterprise feature development; trained 50+ service engineers in 5 cities, standardizing EV diagnostic repair quality.
