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.

As Cloud Security Officer at Deftpower, you make sure our platform stays safe, compliant and trusted as we scale fast across Europe. You design secure cloud architectures, automate compliance and make sure security is part of every build from infrastructure to code.

You'll work closely with Timo, your Team Lead, who currently acts as both Security Officer and CISO. Over time, we'd love to see you grow into these responsibilities and take the lead on security across the company.

You'll be the first in this role, setting the foundation for how we grow securely. You'll balance protection with progress, working side by side with engineers, operations and leadership because at Deftpower, security moves just as fast as innovation.

You fit right in at Deftpower if you know yourself well, what drives you, what you need to do your best work and how to communicate that clearly to others.

  • Deep knowledge of Azure security best practices (vNet, VPN, WAF, network appliances)
  • Skilled in Infrastructure as Code and familiar with ISO 27001
  • Proactive, analytical and not afraid to challenge assumptions
