About The Position

The Mechanical Engineer II will be responsible for the mechanical design and development of distribution transformers in compliance with IEEE, CSA, and customer specifications. This role requires a solid foundation of mechanical engineering design principles as they pertain to structural and thermal requirements unique to transformer applications. This role involves preparation and review of detailed designs and calculations in accordance with applicable standards and manufacturing constraints. Design and Development: Design, develop and review mechanical specifications for distribution transformers, ensuring compliance with customer requirements. Develop mechanical designs for distribution transformers including tank, core-coil frame assemblies, cooling systems, lifting/handling features, etc. as needed for custom and non-standard configurations. Perform mechanical calculations such as structural strength for short circuit forces, thermal performance, and tolerance stack-ups. · Verify bushing locations, terminal clearances and overall component and accessory layouts . Utilize engineering software (e.g., AutoCAD, SolidEdge, or proprietary transformer design tools) for mechanical design, modeling and analysis. Prepare and review manufacturing drawings, bills of materials, and 3D CAD models. Participate, as required, in product development and improvement initiatives to maintain market competitiveness of company products and solutions. Standards and Compliance: Interpret and apply relevant industry standards (e.g., IEEE, ASTM and CSA) to ensure compliance. Participate in design reviews, technical discussions with customers, and root cause analysis of production or issues. Contribute to standardization of transformer designs and development of design tools, templates, and best practices. Stay updated on evolving industry standards, participating in industrial committees and technical events as required. Support certification and testing requirements such as pressure/rupture/vacuum testing, tamper proof/enclosure integrity testing, dielectric, short circuit and arc fault testing, and thermal performance validation. Collaboration and Coordination: Collaborate with manufacturing, test, and quality teams to resolve non-conformances, implement engineering changes, and validate design improvements. Provide technical support to manufacturing and assembly teams, including weld specifications, component/material selection, and fit-up requirements to optimize transformer performance, efficiency, and cost. Participate in process improvement initiatives to enhance departmental efficiencies and output quality, supporting prototype builds, production, and customer testing as required

Requirements
