Description

Enphase Energy is a global energy technology company and a leading provider of solar, battery, and electric vehicle charging products. Founded in 2006, our innovative microinverter technology revolutionized solar power, making it a safer, more reliable, and scalable energy source. Today, the Enphase Energy System enables users to make, use, save, and sell their own power. 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!

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
Who you are and what you bring:
  • B. E/ B. Tech in Electrical Engineering or Computer Engineering or Computer Science.
  • 12+ years’ experience in a similar (non-academic) role as an embedded software or firmware engineer
  • Proficiency scripting language Python to automate software development workflows. 
  • Expertise in embeeded C firmware development on ARM Cortex-M (STM32 strongly preferred).
  • Direct experience with Ethenet PHY/ switch bring-up and driver development (ADI, Microchip, TI, Marvell, Broadcom parts all relevant as transferable experience). 
  • Prior work specifically with ADI's ADIN-family Ethernet PHYs or switches. 
  • Experience with industrial/ embedded network switch products (managed switches, gateways, or similar network-edge hardware). 
  • Familiarity with IEC 61850, TSN, or other industrial Ethernet standards. 
  • Experience implementing or maintaining a firmware update / bootloader mechanism in a shipped product. Implement update integrity checks (checksum/ CRC or cryptographic signature) and safe-fallback/ rollback logic. 
  • Experience with SPI, I2C, UART, and MDIO/ MDC protocols at the driver level. 
  • Debugging with JTAG/ SWD, oscilloscope, and protocol analyzers; comfortable reading datasheets and chip errata.
  • Implement transparent (cut-through or store-and-forward) packet pass-through between switch ports at line rate for 10/100 Mbps. Handle mixed-speed scenarios without buffer overrun or excessive latency. 
  • Implement basic switch management functions: port enable/ disable, loopback/ diagnostic modes, statistics/ error counters. 
  • Familiarity with layer-2 concepts (MAC learning/ aging, broadcast/ flood behavior, optional VLAN tagging) as applicable to the target chip's switching engine. 
  • Being curious and ability to troubleshoot firmware related issues within complex systems. Relentless pursuit of problem-solving skills.
  • Ability to test code and hardware both with and without external test equipment such as oscilloscopes, power meters, etc. 
  • Familiarity with software development processes, Atlassian cloud suite (Confluence, JIRA), Git configuration management.
  • Ability to carry a design task from concept to implementation and verify.
  • Ability to document engineering requirements (like JAMA, Polarion, DOORs), document solutions, and test new firmware designs. 
  • Experience with launching products on production scale to see through customer or field issues for learnings.
