Job descriptionOptimize high-efficiency DC-DC LED driver circuits (Buck / Boost converters) with efficiency > Integrate PWM / MPPT charge controllers with Battery Management Systems (BMS) for LiFePO4 and Li-ion chemistries. Lead PCB layout and schematic capture using tools like Altium Designer or OrCAD , ensuring low EMI / EMC noise. Integrate IoT modules (LoRaWAN, Zigbee, GSM / GPRS) for remote monitoring and dimming controls (dusk-to-dawn logic, motion sensing). Calculate the "Energy Balance" to match PV Panel wattage, Battery capacity (Ah), and LED load to ensure required autonomy (backup days) during cloudy weather Select and simulate secondary optics (lenses) to achieve Type II / Type III light distribution patterns, minimizing light pollution and maximizing road uniformity. PV Modules : Monocrystalline / Polycrystalline / Vertical Solar tech LEDs : High-lumen per watt (LPW) emitters (e.g., Osram, Cree, Lumileds) Thermal Management : Design heatsinks and enclosures to ensure LED junction temperature (Tj) remains within safe limits ( Enclosure Design : Oversee mechanical design (SolidWorks / AutoCAD) to ensure IP65 / IP66 ingress protection and IK08 / IK10 impact resistance. Hands-on experience with oscilloscopes, multimeters, power analysers, logic analysers PCB bring-up, debugging, and performance validation Battery Cycle life testing EMI / EMC pre-compliance testing skills Reliability testing : thermal cycling, vibration, surge / transient protection Familiarity with lighting and electronics compliance standards : BIS, CE, RoHS, REACH Automotive : ISO 26262, AEC-Q100 / 200 Safety : IEC 60598
JOB PURPOSE
Lead the design and development of next-generation solar lighting products (Solar Street Lights, High Masts, and Garden Luminaires).
In this role, the incumbent will own the entire product lifecycle —from component selection (PV, Battery, LED) and driver circuit design to thermal management and mass production. Will bridge the gap between electrical efficiency and mechanical durability, ensuring our products meet global standards (IEC / MNRE) and withstand harsh outdoor environments.
