A Snapshot of Your Day

We’re seeking a skilled and forward-thinking Winding Assembly Design Engineer to join our team at Siemens Energy. In this role, you’ll be responsible for designing winding and winding assembly components for power transformers, including preparing detailed drawings and Bills of Materials (BOMs). You’ll play a key part in driving innovation and optimizing product performance, all while ensuring alignment with Siemens Energy’s design standards, quality benchmarks, cost targets, and project timelines.

This role starts with a unique opportunity to be part of the launch phase of our brand-new manufacturing facility in Charlotte, NC. The facility is planned to be built by early 2026 for production commencement. Consequently, the first part of the journey in this role in our Company will involve overseeing the construction of the factory and the implementation of new processes, as well as managing the development of a high-performance team and coordinating all aspects of the factory setup to prepare for production.

How You’ll Make an Impact

• Interpret electrical design outputs to create detailed manufacturing drawings and Bills of Materials (BOMs) for winding and winding assemblies used in large Power, Auto, and Generator transformers (up to 500 MVA, 550 kV), including sub-assemblies and components.
• Utilize 2D and 3D CAD software to model transformer components and assemblies, supporting the development of precise engineering documentation and BOMs.
• Provide technical support throughout the winding assembly manufacturing process, including quality inspections, failure analysis, and tolerance concessions.
• Collaborate with suppliers and internal teams to resolve design-related queries, recommend alternative solutions, and ensure adherence to quality and performance standards.

How You’ll Make an Impact

• Bachelor’s or Master’s degree in Mechanical or Electrical Engineering with 6+ years of experience in transformer electrical design or winding & assembly design. Those with more experience may be considered for a higher level and vice versa. In lieu of a degree, experience may be considered.
• Expertise in designing various winding types (helical, layer, disc, multi-start) for LV, HV, tertiary, and regulating systems in transformers above 100 MVA / 145 kV is required.
• Familiarity with copper conductor types, including paper-covered strips and CTC (with/without enamel or epoxy).
• Experience in winding assembly design and insulation components (e.g., spacers, barriers, oil guides, molded pressboard parts).
• Knowledge of specialized winding processes such as conductor bending, joint formation, enamel removal, block pressing/sizing, gluing, crimping, and brazing.
• Understanding of dielectric principles, short-circuit forces, and oil flow mechanisms within windings.
• Applicants must be legally authorized for employment in the United States without the need for current or future employer-sponsored work authorization. Siemens Energy employees with current visa sponsorship may be eligible for internal transfers.
• If not already located in Charlotte, NC, must be willing to relocate. Relocation assistance may be provided.
