The role

Job Description:

The Sr. Electrical Product Design Engineer (Wiring and Schematics) will join the R+D+i team to translate the conceptual architecture of the inverters and electrical cabinets into the final technical documentation required for manufacturing. Their primary mission is to design, size, and lay out the internal wiring of the equipment, as well as to ensure that the interconnection of all power and control modules is safe, efficient, and reproducible on the assembly line, while complying with technical specifications and international standards throughout the entire product development cycle.

What you'll do

• Develop detailed engineering drawings, electrical schematics, and wiring diagrams for the high-power inverter.

• Define the technical specifications for interconnections, cable harnesses, connectors, and internal equipment wiring.

• Ensure that the wiring design optimizes space, minimizes electromagnetic interference (EMI), and facilitates the assembly process during production.

• Preparation of electrical schematics: Design detailed electrical diagrams for power, control, signal, grounding, and protection systems using advanced computer-aided engineering (CAE) software.

• Wiring design and sizing: Calculate and select the appropriate conductor cross-sections, insulation types, terminals, conduits, and connectors to withstand high currents, voltages, and temperature gradients.

• Technical routing: Define the optimal cable routing within the inverter chassis, in close collaboration with the mechanical engineer, physically separating power cables from signal cables to prevent electrical noise.

• Preparation of production documentation: Prepare cable lists (from-to lists), connection diagrams, crimping tables, terminal block diagrams, and detailed electrical bills of materials (BOMs).

• Standardization and Regulations: Ensure that all wiring and connections strictly comply with international standards for electrical safety, insulation clearances (creepage distance and clearance distance), and electromagnetic compatibility (EMC).
