Job description

Senior Switchgear Electrical Engineer – Medium & Low Voltage (MV/LV)

Role Summary

The Senior Switchgear Engineer (MV/LV) is responsible for the design, engineering, validation, and technical leadership of medium- and low-voltage switchgear systems. This role provides subject-matter expertise across the full product lifecycle—from concept and specification through manufacturing, testing, installation support, and commissioning—while ensuring compliance with applicable standards, customer requirements, and safety regulations.

Key Responsibilities

Technical & Engineering

• Lead the design and engineering of MV (typically 1 kV–36 kV) and LV (≤1 kV) switchgear systems, including air-insulated (AIS) and gas-insulated (GIS) solutions where applicable.
• Develop electrical schematics, single-line diagrams, wiring diagrams, GA drawings, and protection & control philosophies.
• Specify and select components such as circuit breakers, contactors, relays, busbars, CTs/VTs, protection devices, and interlocking systems.
• Perform electrical calculations including short-circuit, protection coordination, arc-flash, thermal, and dielectric analyses.
• Ensure designs meet performance, reliability, maintainability, and safety requirements.

Standards & Compliance

• Ensure compliance with relevant international and regional standards (e.g., IEC, IEEE, ANSI, UL, NFPA, NEC, CSA).
• Support product certification, type testing, routine testing, and factory acceptance testing (FAT).
• Maintain awareness of evolving industry standards, codes, and best practices.

Project & Customer Support

• Act as technical lead on assigned projects, supporting sales, proposals, and customer technical clarifications.
• Interface directly with customers, consultants, utilities, and inspectors to resolve technical issues.
• Review customer specifications and translate requirements into compliant engineering solutions.
• Provide on-site technical support during installation, commissioning, and troubleshooting as needed.

Manufacturing & Quality

• Collaborate with manufacturing, supply chain, and quality teams to ensure manufacturability and cost-effective designs.
• Support root cause analysis and corrective actions for quality, reliability, or field issues.
• Drive continuous improvement initiatives related to design efficiency, standardization, and product robustness.

Leadership & Mentoring

• Mentor and guide junior engineers and designers as/when needed.
• Review and approve engineering deliverables.
• Contribute to technical documentation, design guidelines, and engineering best practices.

Required Qualifications

• Bachelor’s degree in Electrical Engineering or a related field.
• 8–12+ years of experience in MV/LV switchgear design or electrical power systems.
• Strong knowledge of protection and control systems.
• Hands‑on experience with switchgear testing, commissioning, or field support.
• Proficiency with engineering tools (e.g., AutoCAD, EPLAN, ETAP, SKM, or equivalent).
• In‑depth understanding of electrical safety principles and arc‑flash mitigation.

• Mandarin speaking abilities are a strong plus, but not mandatory
