Senior/Staff Electronics Design Engineer

The role

You will architect, design, and integrate low voltage electrical systems within high-performance power converters. This role spans the full product lifecycle from concept development to production support.

What you will do

• Own the full hardware development lifecycle from requirements to manufacturing support
• Define and implement low voltage electrical architecture for cabinet-based systems
• Select LV components such as microcontrollers, interface circuits, fuses, relays, contactors, terminal blocks, and power supplies
• Create system block diagrams, schematics, and harness documentation
• Ensure electrical interface integrity across PCBs, sensors, actuators, and communication buses
• Collaborate with mechanical teams on enclosure layout, cable routing, shielding, and grounding
• Support validation and bring-up of LV systems during prototype and production builds
• Ensure compliance with safety and regulatory standards such as UL, CE, and IEC
• Coordinate with firmware, test, and manufacturing teams

Required qualifications

• Degree in Electrical Engineering or related field
• 5+ years of experience in low voltage electrical system design
• Strong knowledge of cabinet-level LV power distribution and signal architecture
• Experience selecting and integrating LV components for multi-voltage systems
• 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, volume production, and development of manufacturing test procedures and test equipment

Nice to have

• 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

Benefits

• Competitive compensation (salary and equity)
