Software Engineer

Present in 96 countries, we are dedicated to changing the way the world uses energy through advanced electric vehicle charging and energy management systems. We have our headquarters in Barcelona and manufacturing facilities in Spain (Barcelona) and the US (Arlington, Texas). We are rapidly becoming a leading company in the market.

In 2021, we were listed on the New York Stock Exchange (NYSE WBX), allowing us to garner acclaim and win prestigious design awards (the iF Design Award, Good Design Award, and Red Dot Design Award).

In 2022, we acquired ARES (an electronics assembly company) and COIL (an installer of turnkey EV charging solutions). One year later, in 2023, we acquired ABL, the leading German EV charger manufacturer, which has allowed us to strengthen our presence in Europe.
