over de organisatie

Imagine a future where you can earn 500€ per year just by charging your car. Now imagine a job where you helped make this happen. Our Deftpower team has big ideas for improving electric car charging and draws on more than a decade’s worth of experience in the EV charging business in realising them.

We are rapidly building Europe´s most advanced platform, recalibrating electric vehicle drivers, their cars, charging points and the grid in a sustainable eco-system. One in which everything is integrated, and anyone can join. We believe that this market needs to grow quickly, and that with the right team - our clients and EV drivers can be happier, businesses more profitable, and society cleaner.

Because very relevant people and companies believe in us, we can grow rapidly over the next two years. As a result, we're on the lookout for new, geeky, funny, and brilliant team members to join us! To help us in our mission we are looking for a Business Analyst, for our offices in either Arnhem or Berlin.


For this position, it is important that you are from the EU (Deftpower is not acknowledged referent) and therefore have a work permit to work in the Netherlands or Germany.

With your colleagues you will find out when to charge a car and when not to charge a car. This decision can save loads of money and CO2 if done right. Understanding the energy markets will make this job easier. Here are some of the tasks you will be performing:

1. Algorithm Development:

  • Design and implementforecasting algorithms to enhance the efficiency and reliability of our virtual powerplant
  • Collaborate with the engineering team to integrate algorithms seamlessly into our existing systems (incl. consumer APP)

2. Data Processing and Analysis:

  • Implement data processing scripts to handle real-time data from charging stations, electric vehicles and grid sources.
  • Analyze data to improve system performance, user experience, and provide valuable insights.

3. Code Quality and Testing:

  • Conduct thorough code reviews to maintain high standards of code quality, security, and performance.
  • Collaborate with the quality assurance team to identify and address software bugs and issues.

4. Innovation and Research:

  • Stay informed about industry trends, new technologies, and advancements in EV charging and smart grid solutions.
  • Propose and implement innovative features to enhance our smart charging platform.
