Description
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.
If you are passionate about advancing a more sustainable future this is the perfect time to join Enphase. This role is part of the core Engineering R&D group focused on launching Commercial and Industrial storage products. Our team designs prototypes and scales industryleading storage systems that integrate Enphases core technologiessuch as IQ series microinverters combiners and moreto deliver bestinclass endtoend energy solutions for our customers.
Must be available to work on-site at our Bangalore office 5 days per week.
About the role
As a Principal Mechanical Engineer you will be responsible for the endtoend mechanical architecture detailed design and system integration of commercial and utilityscale Battery Energy Storage Systems (BESS). This includes cabinets racks and containerized platforms using sheetmetal and welded structures cast and machined components polymers and elastomers for insulation and sealing and durable coatings and finishes for longterm outdoor operation.
You will integrate mechanical systems with battery modules highpower electrical assemblies (PCBs contactors protection devices) busbars and cable harnesses ensuring safe electrical clearances thermal performance manufacturability and serviceability. You will also integrate forcedair HVAC and liquidcooling solutions working closely with electrical compliance and manufacturing teams. Through structured problemsolving across new product development and field issues you will drive improvements in reliability safety serviceability and cost.
What you will do:
Ability to independently lead mechanical design projects or guide small teams delivering against schedule cost quality and performance targets.
Extensive experience executing 3D and 2D CAD (SolidWorks EPDM) maintaining releaseready design documentation and leading mechanical and crossfunctional design reviews.
Strong understanding of structural and thermal design for heavyduty outdoor cabinets and containerized systems including fans HVAC and liquidcooling solutions and effective ECAD/MCAD integration.
Demonstrated experience planning and executing prototype builds proofofconcepts and Design Verification Testing (DVT) including rapid design iteration.
Capability to define and execute comprehensive mechanical test plans (inhouse and external labs) covering static/dynamic loads fatigue environmental exposure UL/IEC certification and reliability requirements.
Who You Are and What You Will Bring:
15 years (BE/B. Tech) or 12 years (Masters) of handson experience in mechanical product design development and testing with mandatory experience designing Commercial and Utilityscale Battery Energy Storage Systems (BESS).
Bachelors degree or higher in Mechanical Engineering.
Proven ability to own endtoend mechanical system design and delivery for BESS cabinets racks and containerized platforms including sheetmetal and welded structures cast and machined parts polymers and elastomers and durable outdoor coatings.
Strong handson experience designing integrating and validating electromechanical systems including battery modules highpower electrical components (PCBs contactors fuses breakers) busbars and cable harnesses with focus on safetycritical design electrical clearances manufacturability and longterm serviceability.
Handson experience performing DFMEA failure analysis (FA) and rootcause analysis (RCA) using 8D and whywhy methodologies and driving corrective and preventive design actions.
Strong background in DFA / DFM / DFX for injection molding sheetmetal fabrication stamping milling and turning with continuous focus on cost quality and manufacturability.
Experience optimizing battery module and cell layouts within racks and containers for size weight installation transportation and longterm serviceability.
Working knowledge of global standards and compliance applicable to commercial and utility BESS including:
