Job Description

We are a global scale-up from Barcelona, born in 2015, dedicated to changing the way the world uses energy. We envision a world free from fossil fuels and we believe the first step in this journey is creating solutions that make electric vehicle charging easier for everyone.

We’re devoted to researching and developing state-of-the-art electric vehicle charging solutions for homes, businesses, and cities. And this way, our mission is to create more sustainable ways of using and sharing energy.

We want to empower people to create, use and share renewable energy in ways they never imagined.

Wallbox currently operates in over 50 countries and has offices in Barcelona, Madrid, Shanghai, and San Francisco. We are powered by a culture of trust, innovation and diversity. For us, talent has no borders. We have more than 350 dedicated experts from over 30 different nationalities working together to create the most innovative products and the best experiences for our customers.

This culture has shown to be rewarding in many ways - amongst them, the creation of the world’s first bidirectional charger, the Quasar, and the recognition as the best of CES 2020 in transportation technology. We have recently closed our second tranche of Series A investment, bringing the total round to €23M and we’ve been recognized as LinkedIn's Top 5 Startups 2020 in Spain.

At the end of the day, working at Wallbox is at the same time challenging, fun and rewarding. If you like the idea of a dynamic environment, desire to work alongside an incredibly talented, fast-growing team and believe in the future of sustainable transportation, this is the place for you.

Are you ready to change the world with us?
