Big Data Engineer

Wallbox is a global company, dedicated to changing the way the world uses energy. We do this by creating smart charging systems that combine innovative technology with outstanding design and manage the communication between vehicle, grid, building, and charger.

Founded in 2015, with headquarters in Barcelona and selling already in over 80+ countries, our mission is to facilitate the adoption of electric vehicles today to make more sustainable use of energy tomorrow. Our talent has no borders - we welcome over 700 Wallboxers from over 45 nationalities in Europe, Asia, and the Americas!

We’re now the first Spanish unicorn listed on the NYSE ($WBX) and have been recently named amongst LinkedIn’s top 3 Spanish startups.

Wallbox is committed to become a data driven company, not only for improving our decision making processes but also for helping us drive better our product development and incorporate data into our existing products or even create new business models.

We started our data journey just one year ago and it has already been an amazing drive! We've built a passionate and vibrant team, organized in a hub & spoke model, with roles such as data analysts, data engineers and analytics engineers

Also we've been building a modern data stack, with technologies like Snowflake, Airflow, Fivetran, DBT, Tableau and Databricks.

Today our data lake is ingesting more than 1M events per hour coming from more than 350 sensors in our chargers. And this is just the beginning, as our goal is to reach one million online chargers by 2025.
