Senior Engineer- Mechanical (LV Switchgear)

What You’ll Do

"We are seeking a motivated individual to support the development and maintenance of Low Voltage (LV) switchgears, with a strong focus on Motor protection Circuit Breakers (MPCB), Switch Disconnector, Contactor and Accessories. Success in this position requires effective collaboration, a strong drive to achieve project objectives, and the ability to learn new techniques, tools, and processes for the product development cycle.

Key Responsibilities

Design and develop LV switchgears (AC and DC rated breakers, Switch disconnector contactors, motor relays, auxiliary contacts, and accessories like Under voltage and Shunt release) to meet customer requirements, cost targets, and market-related technology. Complete system/component sizing, designing, simulation, and testing validation to industrialization. Design parts and products considering design for manufacturing and assembly, applying thorough understanding and experience of plastic injection molding, sheet metal, casting, machining processes, and tooling considerations. Conduct engineering analysis of arc chambers, current paths, and contacts for innovative and robust product development. Take technical ownership of subsystems or modules of the project, ensuring product compliance with global standards like IEC60947 or UL489 other relevant compliance standards. Modify existing products to support customer, manufacturing, regulatory, and market requirements through the Change Management process."

"

Experience in Research/NPI/Sustaining projects for Breakers, Switch Disconnector, Contactors, Auxiliary contacts, Accessories or similar products. Expertise in plastic and sheet metal part design, mechanism design, and system integration. Knowledge and experience with plastic materials, their properties, and requirements. Proficiency in GD&T principles and clearance & creepage calculations. Experience with various manufacturing processes for contacts and plastic materials (bending, riveting, welding, brazing, injection molding). Knowledge of low voltage switchgear standards in accordance with IEC/UL/CSA/CCC codes, enabling the development of test plans. Experience in executing tests for EN60947 / UL60947 (temperature rise, short circuit, make/break, sequence tests, etc.). Assess test results, perform root cause analysis through test findings/failures, and implement corrective/preventive actions. Responsible for design engineering analysis on current paths, mechanisms, springs, bimetals, housings, actuators, arc chambers, coils, etc. Review reliability predictions, and be conversant with Design Failure Modes and Effects Analysis (DFMEA) and structural/thermal/CFD/MBD results. Complete detailed design (2D drawings/3D models) in UG-NX, SolidWorks, or Creo. Knowledge of PLM systems (Enovia, SAP) is desirable. Should have an innovative mindset with a proven track record of innovation and product launches."
