Senior LV Hardware Design Engineer - Power Electronics

Heron Power Inc.; Scotts Valley (CA); On-site; USD 140,000 - 200,000; Full time

Job summary

Heron Power Inc. is seeking a Senior/Staff Hardware Design Engineer to architect, design, and integrate the low voltage electrical system within high‑performance power converters for reliability, EMC, and safety.

You will define cabinet‑level architecture, manage harnessing and interconnects, and support the full product lifecycle from concept to production. You will own the hardware development lifecycle, select LV components (MCUs, relays, fuses, terminal blocks), create schematics and harness

Qualifications

• Degree in Electrical Engineering or related field.
• 5+ years of experience in low voltage electrical system design, including cabinet-level LV architecture.
• Strong knowledge of cabinet-level LV power distribution and signal architecture.
• Experience selecting and integrating LV components (relays, fuses, terminal blocks) for multi‑voltage systems.
• Familiarity with harness design, connector systems, and wiring diagrams.
• Understanding of EMC best practices and grounding/shielding techniques.
• Proficiency with electrical CAD tools (e.g., Altium).
• Hands‑on experience with debugging, testing, and validating electrical systems using oscilloscopes, multimeters, and similar tools.
• Experience with manufacturing processes, including DFM and volume production.

Responsibilities

• Own the full hardware development lifecycle—from requirements definition to schematic capture, PCB layout, prototyping, testing, validation, and manufacturing support.
• Define and implement the low voltage electrical architecture for cabinet-based systems, including cabinet microprocessors, power supplies, power distribution, interconnects, and signal processing.
• Select appropriate LV components such as microcontrollers, interface circuits, fuses, relays, terminal blocks, and power supplies.
• Create system block diagrams, schematics, and harness documentation to support cross-functional development and manufacturing.
• Ensure electrical interface integrity across PCBs, sensors, actuators, and communication buses (CAN, RS-485, Ethernet, LV I/O).
• Collaborate with mechanical teams on enclosure layout, cable routing, shielding, and grounding for EMI/EMC performance.
• Support validation and bring‑up of LV systems during prototype and production builds, including DVT and integration testing.
• Ensure compliance with safety and regulatory standards such as UL, CE, IEC for LV systems.
• Coordinate with firmware, test, and manufacturing teams to ensure proper system behavior and serviceability.
