Job 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! About the Role This role sits within CTO team on the Solid-State Transformer (SST) platform team. We design and deliver the embedded firmware for Enphase's next-gen grid-scale energy conversion systems. We are hiring at Staff, Senior Staff, and Principal levels. Every engineer writes code, debugs hardware, and owns outcomes; higher levels carry increasing architecture ownership and technical leadership. What You Will Do • Design and ship firmware for real-time embedded systems in C/C++. • Develop board- and system-level firmware across multi-processor/core platforms (bare-metal, Zephyr RTOS). • Integrate real-time control loops with application and control processors. • Co-define HW/SW boundaries and drive systems bring-up with hardware and power electronics teams. • Drive end-to-end validation — unit tests, HIL, and prototype testing. • Collaborate cross-functionally through DVT, factory test, and field quality. • At senior levels: own platform architecture, lead reviews, mentor engineers, and drive hiring. Who You Are and What You Bring • BS and 8+ years / MS and 6+ years / PhD and 3+ years design experience for a Staff Engineer • BS and 12+ years / MS and 8+ years / PhD and 5+ years design experience for a Sr. Staff Engineer • Candidates with greater levels of experience may be considered and are encouraged to apply • Expert-level C and Modern C++ for real-time embedded applications. • Bare-metal and Zephyr RTOS firmware development. • Experience in functional safety firmware development. • ARM Cortex-M/R microcontroller architectures and peripherals (ADC, PWM, UART, I2C, SPI, CAN). • Comfortability works from low-level driver development through application development. • Hardware bring-up, schematic reading, reading datasheets and driver development. • ARM Cortex-M microcontroller architectures and peripherals (ADC, PWM, UART, I2C, SPI, CAN). • Hardware bring-up, schematic reading, and driver development. • Closed-loop control algorithm implementation on embedded targets. • System testing and debug with oscilloscopes, protocol analyzers, and HIL setups. • Python scripting for test automation and tooling. • Track record of shipping products from concept through manufacturing and field support. Additional Desired Skills • Familiarity with development tools such as Docker, GCC, GDB, VS Code, GNU Make, CMake, etc. • Experience with CI/CD pipelines and containerized build environments using tools such as Docker, Bitbucket Pipelines, or GitHub Actions • Embedded Linux (Yocto, BSP, device tree); ARM Cortex-A processors. • Bootloader design, secure boot, and OTA update mechanisms. • Industrial communication interfaces and protocols: RS485, CAN FD, UWB, Ethernet, Modbus RTU/TCP. • Power conversion, energy storage, grid-connected equipment, or BMS experience. • UL/IEC standards for power electronics products. • Familiarity with UL1998, IEC60730, IEC61850 • Zephyr RTOS. Work Location Austin, TX The base pay range for this position is $110,000 to $183,000 per year. This salary range may be modified in the future. The successful candidate’s starting pay will be determined based on job-related skills, experience, education or training, work location, and market conditions.
