Senior Embedded Hardware Engineer

Senior Embedded Hardware Engineer

In times of increasing resource scarcity, global warming, and environmental challenges, GWF goes the extra mile to measure valuable resources (water, heat, gas, electricity). We are developing new measurements and communication technologies to accomplish double-digit growth and bring cool products to the market.

In Thessaloniki, GWF has established a modern Development Center whose mission is to create fresh smart-metering and IoT solutions that reshape traditional utilities toward smart city paradigms. We want to contribute to the local tech ecosystem and at the same time drive the company’s international growth. The team offers a vibrant environment, passionate bright colleagues, and a clear goal to transform IoT data into modern applications.
