• Control logic, interlocking and communication interface design where required
• Compliance verification against UL standards, NFPA, client specifications and internal quality procedures
• Structured project documentation management
• Familiar with IEC Standards

Electrical Design & Schematics

• Review and interpret client specifications, one-line diagrams and project requirements, translating them into compliant, detailed electrical designs.
• Design low voltage switchgear assemblies in accordance with applicable regional standards
• Develop complete electrical schematic drawings using EPLAN or equivalent software, to the required accuracy and documentation standard.
• Prepare General Arrangement (GA) drawings in close coordination with the Mechanical Design team.
• Select and size electrical components — ACBs, MCCBs, contactors, relays, protection devices and busbar systems — appropriate to the project specification.
• Perform basic electrical calculations including fault level analysis, load calculations, cable sizing, busbar rating and thermal considerations.
• Ensure proper coordination and discrimination of protective devices across all designs.
• Incorporate control logic, interlocking schemes and communication interfaces (Modbus, Profinet, and equivalents) where project requirements demand.

Documentation & BOM Management
