Job Description

As a Senior/Staff Electronics Design Engineer, you will be responsible for architecting, designing, and integrating the low voltage electrical system within high-performance power converters to meet reliability, EMC, and safety requirements. You will define cabinet-level electrical architecture, manage harnessing and interconnects, and ensure proper distribution of power, signals, and control across subsystems. Your work will span the full product lifecycle—from concept development and component selection to schematic capture, validation, and support through production.

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.
