What They Do

Deftpower B.V. is a private cleantech startup focused on developing software for integrating renewable energy sources such as solar and wind energy into electric vehicle (EV) charging. Their technology includes an AI-supported SaaS platform and a white-label mobile application that enables smart charging, allowing vehicles to connect with networks, energy markets, and over 2,000 charging point operators across Europe. This allows them to reduce costs by up to 20% through dynamic pricing and prepare for vehicle-to-grid (V2G) functionality (source: cbinsights.com). Deftpower serves a wide range of clients, including e-mobility service providers, charging point operators, car manufacturers, energy suppliers, and grid operators, and has a platform that processes millions of transactions in 10 European countries (source: deftpower.com). Their products include a branded app for drivers that provides access to over 800,000 charging points, a business portal for electricity trading and fraud prevention, and developer APIs compatible with OCPI and ISO15118 protocols (source: deftpower.com).

Projects & Track Record

Deftpower has built an impressive track record by implementing its platform for over 40 clients managing widespread EV charging solutions. A notable project is the ongoing smart charging trial launched on May 15, 2025, in Amsterdam, designed as a potential model for global cities by optimizing grid load and renewable integration (source: cbinsights.com). Collaboration with over 40 EV brands and 2,000+ charging point operators strengthens their market position, although specific client names have not been disclosed (source: deftpower.com). Deftpower's platform is active in 10 European countries, focusing on expansion funded by their recent €12.5 million funding round (source: 4impact.vc).

Recent Developments

In the past two years, Deftpower secured €12.5 million in funding on August 29, 2025, led by Endeit Capital with participation from 4impact capital, Proeza Ventures, Rethink Mobility, and Jan Fredriks, supported by the EU's InvestEU Fund. This funding is intended to drive European expansion and AI enhancements for their platform (source: 4impact.vc). The Amsterdam smart charging trial, which began on May 15, 2025, marks a significant milestone in the practical implementation of their technology (source: cbinsights.com). So far, no acquisitions, mergers, awards, or additional certifications have been reported in the sources from 2024-2025, although CEO Jacob van Zonneveld's previous role in founding Plugsurfing (acquired by Fortum in 2018) highlights the continuity of leadership (source: vehicle-2-grid.eu).

Working at Deftpower

Deftpower currently has approximately 70 employees, growing from just over 50 previously. Roles include software development (API and backend for EV integrations), product management, sales, business development, customer service, and operations within engineering, IT, and cleantech functions in an agile team structure (source: 4impact.vc). The company has offices in Arnhem and Berlin, focusing on growth in EV software amid European expansion (source: deftpower.com). The company culture emphasizes technical excellence, rapid execution, and creating clarity from the chaos of the industry, with values aimed at stakeholder success, both economically and ecologically (source: deftpower.com). Specific benefits are not documented in public sources.

Job Description

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 and teaming up with companies in over ten countries.

About the team

You join the Portal team, the team responsible for the customer-facing platform that operators and clients use every day. You work closely with the Product Owner, Product Designer and backend developers. As well as with the Transaction, Roaming, and Smart Charging teams to make sure what gets built in the backend can actually be experienced well in the frontend.

The Portal team is moving fast. We're raising the bar on frontend quality, modernising architecture and integrating AI workflows into daily development. There's a lot to build and a lot of room to shape how we do it.

Our Tech Stack

The Deftpower platform is built in C#/.NET. We are heavily using Azure Functions to keep our platform as scalable as possible. We adopt a microservice architecture where services communicate with each other mainly via the Azure Service Bus. Data storage is done in a variety of ways, but Cosmos and Azure SQL databases are used most. Monitoring and logging is done with Application Insights and Grafana as well as PowerBI dashboards. The portal that interacts with the backend is written in Angular, while our mobile applications are developed in React Native. In general, we use Azure's PaaS components wherever possible to stay up to date and ready for scale.

"Everyone is driven to make customers happy, we don't just work for the sake of working."

- Florian, Team Lead

About the job

As Frontend Developer at Deftpower, you own the quality of what users see and touch. You translate Figma designs into responsive, accessible Angular components, set the standard for how frontend work gets done, and make sure the codebase stays clean and maintainable as we scale. This isn't a role where you wait for tickets, you proactively address technical debt, hold the bar in code reviews, and contribute to architectural decisions.

You also work with AI. Claude Code, custom agents, prompt engineering, these are part of your toolkit, not a future ambition. You use them to move faster and build more consistently.

  • Develop and maintain features in the Angular customer portal from implementation to release
  • Translate Figma designs into responsive and accessible UI components using Kendo UI and the internal component library
  • Own test coverage for delivered features, including unit and integration tests
  • Take ownership of frontend architecture decisions and set coding standards for the team
  • Identify and address technical debt proactively, not only when it blocks delivery
  • Use and improve AI workflows to increase development speed and consistency

What your new colleagues say

Anja, Office Manager ''Everyone is incredibly committed and motivated to make something of Deftpower.''

Wierd, Teamlead Smart Charging "No politics, no unnecessary hierarchy. People say what they think and are honest."

Tim, Operations ''The connection between the charging pole, the car, and our app makes us unique. It's tangible technology anyone can understand.''

Timo, Team Lead "On day 1, after onboarding, you can already deliver something for a customer. You make impact very quickly."

For you

At Deftpower you'll find more than cutting-edge tech, you'll find a team that actually enjoys the ride! Colleagues say we are ambitious, friendly and flexible, with just the right amount of chaos to keep things interesting. Working at Deftpower is both rewarding and challenging. There are many moving parts, partners, suppliers, clients and we are a fast growing company that is still learning. You get support from talented colleagues and a management team that's close, approachable and ready to roll up their sleeves. You get the space to shape your role, to take initiative, to make real decisions, test ideas, and yes, sometimes break things. We call it 'learning fast'...

  • Salary range: Between ???4500,- and ???5500,- a month
  • ???2.000 training budget per year to keep learning and growing.
  • Choose your own laptop to work with, up to ???1.750.
  • A flexible setup with hybrid working, short decision lines and a high level of trust.
  • All conditions such as holiday allowance, 25 vacation days, pension, etc.

"I've never once looked at my watch hoping the day would be over. Everything I do feels meaningful."

Michael - Business Development Manager
