Staff Engineer, Firmware DVT

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:

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.
• Strong Python programming experience controlling test equipment and analyzing data; experience with Ruby is a plus.
• Experience across the stages of embedded firmware design implementation test deployment and maintenance.
• In-depth knowledge of relevant worldwide standards such as IEEESA CA Rule 21 HECO SRD 1.1 AS/NZS 4777.2:2015 SAND2013-9875 UK G83/2 and Sandia standards.
• Knowledge of worldwide advanced grid functions and fault conditions.
• In-depth familiarity with AC grid simulators and solar panel simulators.
• Demonstrated technical leadership: leading test strategy influencing design-for-test and mentoring engineers.
• Experience establishing continuous-integration (CI) pipelines for embedded firmware test.
• Experience with grid-code certification testing and interactions with certification/test labs.
• Hands-on experience with advanced grid-support function testing (volt/VAR frequency-watt ride-through) across multiple regional grid codes.
