Senior Engineer - Engineering Design (Solar Lighting)

Description

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.

• PCB bring-up, debugging, and performance validation
• Enclosure Design: Oversee mechanical design (SolidWorks/AutoCAD) to ensure IP65/IP66 ingress protection and IK08/IK10 impact resistance.
• Collaborate with product management, design, and engineering teams to align technology development with market trends and customer needs.
• Optimize high-efficiency DC-DC LED driver circuits (Buck/Boost converters) with efficiency >95%.
• Lead the identification, exploration, and development of cutting-edge Solar lighting technologies and architectures.
• Drive proof-of-concept development for new lighting solutions, including advanced LED systems, smart controls, optics, Battery management, and materials.
• Select and simulate secondary optics (lenses) to achieve Type II / Type III light distribution patterns, minimizing light pollution and maximizing road uniformity.
• Own the technology roadmap for solar lighting developments and scout emerging technologies and academic research for potential integration.
• Lead PCB layout and schematic capture using tools like Altium Designer or OrCAD, ensuring low EMI/EMC noise.
• Calculate the "Energy Balance" to match PV Panel wattage, Battery capacity (Ah), and LED load to ensure required autonomy (backup days) during cloudy weather
• Engage with external partners, universities, and technology consortia to enhance innovation capabilities.
• Thermal Management: Design heatsinks and enclosures to ensure LED junction temperature (Tj) remains within safe limits (<85°C) at high ambient temperatures
• Conduct feasibility studies, risk assessments, and design experiments to validate novel concepts.
• Integrate IoT modules (LoRaWAN, Zigbee, GSM/GPRS) for remote monitoring and dimming controls (dusk-to-dawn logic, motion sensing).
• Prepare and present technical reports, patent filings, and investment cases for leadership review.
• Integrate PWM/MPPT charge controllers with Battery Management Systems (BMS) for LiFePO4 and Li-ion chemistries.
• Mentor junior engineers and build technical excellence within the team.
