About the roleThe Enphase Power systems innovation team in the office of the CTO is responsible for defining, designing, integrating, and validating next-generation system hardware solutions. The team is multidisciplinary, hands-on, and focused on delivering robust designs from concept through production.
Enphase Energy is seeking a Staff Electronics Hardware Engineer to develop, integrate, and validate system-level electronic hardware for new and existing products. This role is focused on system architecture, digital and mixed-signal design, hardware/firmware integration, and full ownership of hardware execution from requirements to release.
What you will do- Create innovative system-level embedded hardware designs to support next-generation energy system products.
- Lead specification, design, schematic capture, prototyping, and debugging of complex circuits and PCBAs.
- Design digital circuits including processor/MCU support, memory, clocking, reset, and interface connectivity.
- Implement and debug digital interfaces including CAN, UART, I2C, and SPI.
- Interface digital subsystems with analog circuitry, including ADC and DAC integration.
- Define and validate mixed-signal performance requirements such as signal conditioning, filtering, grounding, reference accuracy, noise coupling, and timing.
- Perform hands-on board bring-up, hardware validation, and troubleshooting using oscilloscopes, logic analyzers, protocol analyzers, and standard bench equipment.
- Collaborate closely with firmware engineers on peripheral enablement and board bring-up; provide basic firmware-level debug support where needed.
- Own PCB design quality with attention to signal integrity, EMI/EMC, manufacturability, and testability.
- Generate complete design documentation and release packages, including schematics, layout deliverables, BOMs, test plans, and manufacturing outputs.
- Support design transfer to manufacturing and resolve hardware issues through validation and product ramp.
Who you are and what you bring- BS/MS in Electrical Engineering or closely related discipline.
- Staff level: typically 8+ years of electronics hardware/system design experience (or equivalent depth of experience).
- Strong digital and mixed-signal hardware design skills with commercial product development experience.
- Demonstrated experience implementing and debugging CAN, UART, I2C, and SPI.
- Experience interfacing analog and digital circuitry, including ADC/DAC integration.
- Proven hands-on ownership of both schematic capture and PCB layout.
- Familiarity with basic embedded firmware development for hardware bring-up (register-level/peripheral configuration/debug support).
- Proficiency with one or more ECAD tools such as Altium, OrCAD, KiCad, or Expedition (Xpedition).
- Strong troubleshooting ability within complex system environments and ability to drive issues to resolution.
- Ability to independently own technical workstreams and deliver high-quality results on schedule.
Additional desired skills- Strong proficiency with Cadence OrCAD (schematic capture) and Allegro (PCB layout) preferred.
- Experience with analog circuit design, signal conditioning, and low-noise mixed-signal layout practices.
- Experience with isolated circuits and practical isolation boundary implementation.
- Familiarity with small switch-mode power supplies (
- Experience with EMI/EMC mitigation, pre-compliance testing, and production readiness (DFM/DFT, NPI).
TravelOccasional domestic travel.
The base pay range for this position is $100,000 to $151,000. 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. This position is also eligible for bonus, equity, and benefits.
