Job summary

Enphase Energy in Austin, TX is seeking a Senior Electronics Hardware Engineer to design, integrate, and validate system-level hardware for next-generation energy products. You will own hardware execution from requirements through release, focusing on digital and mixed-signal design.

Join a multidisciplinary team that brings hardware and firmware together, driving manufacturability, testability, and DFM/DFT across the product ramp.

Qualifications

• 8+ years of electronics hardware/system design experience (or equivalent depth).
• Strong digital and mixed-signal hardware design skills for commercial product development.
• Experience implementing and debugging CAN, UART, I2C, and SPI.
• Experience interfacing analog and digital circuitry, including ADC/DAC integration.
• Hands-on ownership of schematic capture and PCB layout.
• Familiarity with embedded firmware development for hardware bring-up.
• Proficiency with ECAD tools such as Altium, OrCAD, KiCad, or Expedition.
• Ability to drive issues to resolution in complex system environments.

Responsibilities

• Create innovative system-level embedded hardware designs for 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, grounding, reference accuracy, noise isolation, and timing.
• Perform hands-on board bring-up, hardware validation, and troubleshooting with oscilloscopes and logic analyzers.
• Collaborate with firmware engineers on peripheral enablement and board bring-up; provide basic firmware debug support.
• Own PCB design quality with attention to signal integrity, EMI/EMC, manufacturability, and testability.
• Generate 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.
