Technical Administrative Manager (M/F - 80-100%)

About the job

It all began in 1895, when the young company Société Electrique d’Aubonne (SEFA) was entrusted with the dual mission of implementing a tramway connecting Allaman, Aubonne, then Gimel, and of exploiting the waters of the Aubonne to produce the electricity necessary for its operation and the development of this region. 130 years benefiting technology and entrepreneurship, a history we are proud of!

Building on this past, SEFA also has dreams for the future, in line with today’s needs and tomorrow’s solutions, as well as the desire to continue contributing to the sustainable development of our beautiful region for a long time to come. Our vision is to support our clients with a 100% local offer of sustainable and intelligent services in energy, multimedia, mobility, and municipal services.

If you too are guided by strong values in your daily actions for your clients and your region, and want to participate in the energy transition to meet the constant growth and exciting challenges ahead, join us!
