Data Engineer - eMobility (SaaS)
At Deftpower we're looking for a Data Engineer to join our Business Development team.
About Deftpower
At Deftpower, we’re shaping the future of electric charging every single day. Our SaaS-platform helps businesses across Europe make charging simpler, smarter and more sustainable. With AI and intelligent software, we make sure charging works seamlessly with the energy grid, creating a greener and more stable system for everyone.
We’re growing fast, thanks to a recent major investment, and there’s never a dull moment! We’re expanding, improving our technology. We hope our team of 85 grows to 125 by the end of this year!
About the team
You join our Business Development team, based in Berlin and Arnhem. We work closely with Sales, Product and Operations to identify new opportunities and build strong partnerships across Europe. The focus is on growing the market in a smart and sustainable way, always starting from real client needs.
The team currently consists of five people and is moving quickly towards a more data driven way of working. While Deftpower has four Data Engineers in house, there is no dedicated data support for Business Development yet. This means you will build a lot yourself, from insights to structure, while having the knowledge and support of the wider organisation within reach.
“I’ve never once looked at my watch hoping the day would be over. Everything I do feels meaningful.”
Michael - Business Development Manager

You’ll collaborate with product, operations, engineering and finance to make sure our data isn't just there, but works for us.
