Electronics Design Engineer

Responsibilities

• Heron Power is a startup company building cutting-edge power electronics for the 21st-century grid. We aim to debottleneck the growth of electricity generation and consumption with scalable, innovative, and less costly hardware solutions, accelerating the electrification of everything.
• Job Overview
• How You Will Contribute
• Own the full hardware development lifecycle-from requirements definition and modeling through 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 and routing.
• Select appropriate LV components such as microcontrollers, interface circuits, fuses, relays, contactors, terminal blocks, and power supplies based on system requirements and reliability targets.
• 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 (e.g., CAN, RS-485, Ethernet, LV analog/digital I/O).
• Collaborate with mechanical teams on enclosure layout, cable routing, shielding, and grounding strategies 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, and IEC for low voltage systems.
• Coordinate with firmware, test, and manufacturing teams to ensure proper system behavior, integration, and serviceability.

Requirements

• We're open to candidates with both mid and senior-career experience. Scope and responsibilities will scale with the right candidate.
• Must-Have Requirements
• Degree in Electrical Engineering or related field.
• 3+ years of experience in low voltage electrical system design, including cabinet-level LV system architecture and component designs, ideally in energy, automotive, or industrial control applications.
• Strong knowledge of cabinet-level LV power distribution and signal architecture.
• Experience selecting and integrating LV components (relays, fuses, terminal blocks, etc.) for multi-voltage systems (e.g., 12V, 24V, 48V).
• Familiarity with harness design, connector systems, and creating electrical schematics 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 design for manufacturability (DFM), volume production, and development of manufacturing test procedures and test equipment.
• Experience with LV systems in high-voltage environments
• Familiarity with fieldbus communication protocols like CAN or industrial ethernet.
• Knowledge of control cabinet UL/IEC compliance and wire derating, spacing, and thermal considerations.
• Experience in creating wiring harnesses and managing cable assemblies with third-party suppliers.
• Exposure to cross-functional design with firmware and mechanical engineering teams.
• Experience with failure mode analysis and root cause investigations of LV electrical systems.
• Knowledge of safety-critical system design, including interlocks and redundant controls.
• If you are passionate about technology and enjoy working in a fast-paced environment, we would love to hear from you. Join us in accelerating the electrification of everything at Heron Power.
