Enphase Energy is a global energy technology company and leading provider of solar, battery, and electric vehicle charging products. Founded in 2006, Enphase transformed the solar industry with our revolutionary microinverter technology, which turns sunlight into a safe, reliable, resilient, and scalable source of energy to power our lives. Today, the Enphase Energy System helps people make, use, save, and sell their own power. Enphase is also one of the fastest growing and innovative clean energy companies in the world, with approximately 80 million products installed across more than 160 countries.     We are building teams that are designing, developing, and manufacturing next-generation energy technologies and our work environment is fast-paced, fun and full of exciting new projects.  Must be available to work on-site at our Bangalore office 5 days per week.About the role:As a Senior Mechanical Engineer, you will contribute to the mechanical design and integration of sensors and protection systems alongside other mechanical, firmware, and hardware engineers for MW/MWh-scale utility Battery Energy Storage Systems (BESS) serving data centers, spanning outdoor cabinets and containerized platforms.This role requires hands-on experience in mechanical and structural design and the packaging and integration of sensors and protection devices — fire, smoke, hardware interlock, ground fault, arc suppression, pressure, temperature, and other types — necessary for BESS safety and protection compliance. You will work closely with thermal, electrical hardware, sensors/firmware, sourcing, manufacturing, and quality teams to ensure the product meets safety, performance, reliability, manufacturability, serviceability, and cost targets — contributing to production-ready designs from concept through deployment while optimizing BOM cost.What will you do: <ul style="margin-top:0.0in;"><li
