    • Build and scale domain capability through coaching and knowledge transfer 
    • Support factories, R&D teams, and customers with technical expertise 

Your background:

  • Strong knowledge of solid insulation systems (cellulose, pressboard, barriers) 
    • Strong knowledge of liquid insulation (mineral oil and alternative fluids) 
    • Understanding of material–fluid interaction, aging, moisture behavior, and degradation mechanisms 
    • Ability to connect dielectric design with material behavior and long-term reliability 
    • Background or exposure to materials science, electrochemistry, or polymer behavior is considered an advantage 

    • Degree in Electrical Engineering or related field 
    • 10–15+ years of experience in industry, preferably R&D and Transformers 
    • Strong expertise in insulation systems and dielectric design
