As a Senior Electronics Design Engineer, you will own and drive the board architecture for our interconnect products - from power-conversion, metering, and control architecture through verification and production. This is an ownership role, not a pure execution one: you will set technical direction, make the architecture and component-selection decisions, and partner closely with firmware, mechanical, manufacturing, and test engineering to bring robust, cost-effective products to market.
Essential Duties and Responsibilities
- Own and drive the board architecture - partitioning, interface definition, component selection, and power architecture
- Design analog, digital, and mixed-signal circuits: AC-DC power supplies, DC-DC converters, power management, signal conditioning, sensor interfaces, communications, and embedded control systems.
- Design and validate AC voltage, current, and power measurement circuits, including revenue-grade metering, with attention to accuracy, calibration, and applicable standards.
- Design high-power relay and relay-drive circuits for load switching, including coil drive, snubbing, contact protection, and coordination with embedded control.
- Perform schematic capture, component selection, simulation, PCB design reviews, and hardware debugging.
- Balance design tradeoffs across performance, cost, reliability, manufacturability, and schedule.
- Apply functional safety and safety-critical design principles throughout, including DFMEA and compliance with standards such as UL 991.
- Drive Design for Excellence (DFx) - Manufacturability, test, reliability, and cost.
- Develop and execute verification and validation plans spanning bench, environmental, and system-integration testing.
- Support new product introduction (NPI) through pilot builds, design verification, and production launch.
- Support manufacturing and production at scale - resolving production issues and root-causing hardware failures across development, validation, manufacturing, and the field.
- Work with suppliers to evaluate components and resolve technical issues.
- Collaborate with firmware, mechanical, manufacturing, quality, and test engineering to deliver robust, cost-effective products.
- Mentor engineers and provide technical leadership through design reviews, design standards, and architecture decisions.
- Stay current with industry design trends and provide a roadmap for applying new technologies to our products.
- Improve engineering processes, design standards, and documentation.
Minimum Qualifications
- Bachelor of Science in Electrical Engineering, Electronics Engineering, or related discipline.
- 5+ years of experience in mixed-signal electronic hardware design & product development.
- Experience designing products through full product development cycles and into production.
- Strong background in analog and digital circuit design.
- Hands-on experience with power-conversion design (AC-DC and/or DC-DC) and microcontroller-based embedded control systems.
- Demonstrated experience owning and driving board-level architecture - defining partitioning, interfaces, and design tradeoffs - not solely executing schematic and layout to a given spec.
- Knowledge of AC voltage, current, and power measurement, including revenue-grade metering and the associated accuracy and calibration considerations.
- Knowledge of high-power relays and relay-drive circuit design for load switching.
- Knowledge of functional safety and safety-critical design, including DFMEA and safety standards such as UL 991.
- Ability to work with firmware, read and understand requirements, and modify firmware to support hardware bring-up and test, with hands-on use of UART and CAN bus monitoring tools.
- Experience with schematic capture and PCB layout review using Altium Designer or similar PCB and schematic capture tools.
- Experience debugging complex electronic systems using oscilloscopes, logic analyzers, and other laboratory equipment.
Preferred Qualifications
- Master's or PhD degree in Electrical Engineering or related discipline.
- 7+ years of experience developing electronic products for high volume manufacturing.
- Experience with a range of communication protocols (CAN, UART, SPI, I²C, Ethernet, USB) and related hardware.
- Experience with hardware validation, reliability testing, and regulatory compliance.
- Familiarity with simulation tools for analog, power, and signal integrity analysis.
- Experience with Design for Manufacturability (DFM), Design for Test (DFT), Design for Reliability (DFR), and Design for Cost (DFC).
- Familiarity with automated test development and fault injection techniques.
- Strong analytical and troubleshooting skills with the ability to manage multiple projects simultaneously.
- Excellent written and verbal communication skills and the ability to work effectively on cross functional teams.
- Experience with renewable energy, battery systems, power electronics, or RF design is strongly preferred, given the residential energy focus of our products.
