Enphase is also one of the most successful and innovative clean energy companies in the world, with more than 80 million products shipped across 160 countries.

Join our dynamic teams designing and developing next‑gen energy technologies and help drive a sustainable future for clean energy.

As Principal Product RE, you will own end‑to‑end product development, integrating inverter hardware with cooling/thermal systems, safety, and controls—connecting to the BMS and Site EMS—for utility‑scale Battery Energy Storage Systems (BESS) spanning outdoor cabinets and containerized platforms. You will lead the design of liquid‑cooled, air‑cooled, and hybrid thermal systems supporting multi‑MW/MWh BESS installations operating in data centers.

This role requires deep, hands‑on expertise in inverter system design, thermal cooling, advanced simulation, and BESS safety compliance. You will lead a team of hardware, firmware, and mechanical engineers across thermal, site controls, sensor/safety, and manufacturing functions to ensure the product meets performance, reliability, manufacturability, serviceability, compliance, and cost targets—delivering production‑ready designs from concept through deployment while optimizing CAPEX and long‑term OPEX.

• Develop in‑house or outsourced thermal cooling solutions (liquid cooling, heat exchangers) across the full product lifecycle.
• Work in cross‑functional teams of inverter hardware, firmware, test automation, and mechanical engineers, including teams spread across geographies such as Bangalore, India.
• Specify, design, verify, and debug complex site controls connecting to the BMS (battery management system) and EMS (energy management system).
• Integrate grid‑scale inverter PCS with MWh‑scale DC BESS for data centers.
• Participate in early‑stage product development, communicate expectations, and ensure successful capture of design, manufacturing, supply chain, quality, test, and service requirements.
• Develop schedules for new product development from concept to launch—setting milestones, assessing and mitigating risks, building action plans, coordinating activities, and driving results across cross‑functional teams.
• Conduct regular project status meetings with the project team and stakeholders to communicate and coordinate activities.
• Deliver new products on time, within budget, and at the expected quality and reliability levels.
• Serve as the central technical leader across mechanical, electrical, and firmware engineering, cloud/mobile software, quality, manufacturing, and supply chain/operations.
• Guide daily engineering tasks, including schedule prioritization and tracking the status and resolution of bugs/issues.
• Facilitate initial build plans, drive material readiness with supply chain, and evaluate constraints.
• Collaborate with engineering teams to solve technical problems and provide rapid prototyping support.
• Collaborate with manufacturing and quality teams to develop efficient methods for assembling and testing products.
• Generate high‑value ideas and transform them into platform‑level designs.
• Support system architecture, cost‑reduction proposals, and failure root‑cause analysis.
• Engage with internal technical communities and contribute to cross‑team knowledge sharing.
• Mentor and grow engineers on the team.
• Lead efforts to meet grid code requirements and certifications (UL and IEC) for BESS applications serving data centers.
• Define engineering requirements, develop test plans, and deliver proofs of concept (POCs).
• Champion technical excellence, rigorous documentation, and scientific discipline.
• Serve as a subject matter expert for next‑generation platforms.

• B.E. with 15+ years of relevant industry experience, or a Master's degree with 13+ years of…
