Manufacturing Transfer Work closely with: Manufacturing Quality Supply Chain Procurement NPD Service to achieve: Design → Prototype → Pilot → Mass Production Responsibilities include: DFM/DFA BOM optimization Component localization Test fixtures End-of-line testing Production calibration Yield improvement Cost reduction 10. Cost Engineering The leader must build products that can compete with Chinese and Indian manufacturers. Own: Target Cost → Design Cost → BOM Cost → Manufacturing Cost → Gross Margin Focus on: Component localization BOM reduction Design simplification Common platforms Supplier development Power density Manufacturing yield 11. Engineering Team to Build The Head of Engineering should build the following organization: Team Initial Strength Head – Power Electronics 1 Power Electronics Engineers 4–6 Embedded/Firmware Engineers 4–6 BMS Engineers 3–4 EMS/Software Engineers 3–4 Hardware Engineers 3–5 Mechanical/Thermal Engineers 2–3 Battery Pack Engineers 2–3 System Engineers 2–3 Testing & Validation 5–7 Certification/Compliance 2 Reliability Engineers 2 NPD/Project Managers 2–3 Initial team ~35–50 The organization can subsequently scale to 75–100+ engineers as Loom develops multiple product platforms. 12. First 12-Month Deliverables The leader should be evaluated against concrete product milestones. 0–90 Days Build engineering organization Finalize product roadmap Select technology architecture Identify OEM/technology partners where required Establish laboratory requirements Freeze first-product specifications Create engineering SOP/NPD process 3–6 Months Working hybrid inverter prototype Battery pack prototype BMS prototype EMS prototype Cloud monitoring prototype Initial laboratory validation 6–9 Months Engineering validation Field trials Certification Manufacturing prototype Reliability testing 9–12 Months Mass-production-ready Loom hybrid inverter + BESS platform with: Certification Production BOM Manufacturing test system Service manual Installation SOP Warranty framework Remote monitoring Field-service architecture 13. Key KPIs The Head of Engineering will be measured on: KPI Target Product development cycle ≤ 9–12 months Prototype success rate >90% First-pass certification >90% Product efficiency Industry competitive Field failure rate <1% Engineering change after launch <5% BOM cost reduction 10–20% annually Localization >70% initially, increasing On-time NPD >90% Warranty cost <1–2% of sales Product gross margin Company target New products launched 3–5/year 14. Candidate Profile Must Have 12+ years in power electronics Strong inverter experience Hybrid inverter/PCS experience BESS experience BMS understanding Embedded systems experience Product development experience Manufacturing-transfer experience Certification experience Team-building experience Preferred Experience with companies/products involving: Solar inverter Hybrid inverter PCS BESS Lithium battery EV power electronics Energy storage EMS Microgrid Experience working with Indian and Chinese engineering/manufacturing ecosystems would be a major advantage. 15. Leadership Expectations This is not a conventional R&D manager role . The person must be able to: Think like a CTO + engineer + product manager + manufacturing leader. They must be comfortable moving between: Customer → Product → Circuit → Firmware → Prototype → Factory → Certification → Field and personally solve critical engineering problems. Requirements Look for senior engineers/leaders from companies involved in: Solar inverters BESS Power electronics EV chargers UPS Industrial drives Energy storage EV powertrain Potential talent pools include organizations such as Sungrow, Huawei Digital Power, Delta Electronics, Schneider Electric, ABB, Siemens, Luminous, Su-Kam, Exide Energy, Amara Raja, Waaree, Enphase, Growatt and GoodWe , among others.
