• 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.
• Senior level: Bachelor's Degree with 8+ years of electronics hardware/system design experience (or equivalent depth of experience) or Master's with 5+ years of electronics hardware/system design 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.
