This role at Enphase requires working onsite only

About the role:

This position is part of the core Engineering R&D group, which focuses on launching Residential and Commercial/Industrial storage products. Our team is responsible for designing, prototyping, and launching Storage Systems at scale — cutting edge solutions that integrate Enphase's core technologies like IQ series microinverters, home energy ecosystem of EV chargers, combiners, and more that are best in the market to deliver complete solutions for our consumers. We're looking for a motivated individual who thrives in a fast-paced environment and can collaborate closely with the team to develop and deliver innovative solutions.

What you will do:

• Lead a team of firmware engineers developing requirements, code for system integration, batteries and inverters
• Develop board level and system/product level embedded software for solar and battery-based products.
• Work with hardware and system engineers to conceptualize and document the firmware design architecture for implementation.
• Leverage AI usage to develop EVT (engineering validation testing) by the firmware engineers to verify sanity
• Work with cross function teams like SDVT (system design validation testing) engineers to test and troubleshoot prototype designs.
• Mentor junior engineers and be able to work on residential and commercial product domains seamlessly
