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.

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
