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:

Our microinverters control the flow of power from millions of solar panels and counting. As distributed renewable energy resources proliferate, our microinverters need increasingly advanced high-speed controls to manage the voltage and frequency of next-generation smart grids.

This position Staff Engineer, Firmware DVT sits within our Inverter Design group, where you will work with a small team to develop fully functional prototypes that demonstrate new, advanced operation and control for autonomous grid connection, management, and regulation. As a Staff Inverter DVT (Design Verification Test) Engineer, you will own and drive the verification and test strategy for Enphases inverter firmware - ensuring it meets engineering requirements, design specifications, and worldwide safety and grid standards. You will also coach and mentor other engineers and contribute to the teams technical direction.

What will you do:

• Develop test strategies and plans to verify that Enphases inverter firmware functions per engineering requirements and design specifications.


• Develop and execute test strategies to ensure safety and optimal functionality of Enphases solar microinverter products to meet worldwide standards.


• Design and implement automated test systems in Python and Ruby, enabling continuous integration for the firmware development team.


• Collaborate with hardware and firmware engineers to ensure firmware is designed for test.


• Confer with Quality Assurance, Development, and Product Management on project planning, and ensure effective testing of Enphases products within design constraints.


• Use test automation, power meters, oscilloscopes, DC supplies, and other lab test equipment to ensure complete functional, efficiency, and safety test coverage for Enphases solar microinverter hardware and firmware.


• Coach and train new members of the technical staff on Enphases test equipment, procedures, and automation software.


• Provide technical leadership and mentor junior engineers.

Who You Are and What You Will Bring:

• B.E / B. Tech in Electrical Engineering and/or Power Electronics/Power Systems.


• 8+ years of experience in a similar role as an embedded firmware test/DVT/QA engineer.
