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).

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).

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 commercial side of Deftpower, where Business Development, Sales, Product and Operations work closely together to accelerate the adoption of smart charging across Europe. This role sits on the demand side of our flex ecosystem: you win CPOs (AC, DC/HPC and home/private) as flex-demand partners, turning the flexibility already sitting on their networks into something we can monetise and share back with drivers. You report to Lucas, Head of Sales.
"I've never once looked at my watch hoping the day would be over. Everything I do feels meaningful."
Michael - Head of Product
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 ???60.000,- and ???90.000 on an annual basis
- 25 vacations days
- Choose your own laptop to work with (???1.750,-)
- A flexible setup: hybrid working, short decision lines and trust
- ???2.000,- training budget a year
What your new colleagues say
Anja, Office Manager ''Everyone is incredibly committed and motivated to make something of Deftpower.''
Wierd, Head of Engineering "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, CISO "On day 1, after onboarding, you can already deliver something for a customer. You make impact very quickly."
About the job
As Business Development Manager for Flex Partnerships, you turn charge point operators, DSOs and TSOs into flex-demand partners. You identify which players have the most to gain from steerable load and you use Deftpower's existing flexibility playbook, cashbacks, off-peak rewards, OCPI steering, to build the commercial case that gets contracts signed.
This is a role for someone who enjoys long, technical sales cycles with multiple stakeholders and who can hold their own across commercial, technical and energy-market conversations. You bring a strong narrative, sharp negotiation instincts, and the patience to time demand-side growth against what our driver base can actually deliver.
- Map and prioritise partners with the most to gain from a deal
- Build the commercial case and negotiate the contract that gets them on board
- Represent Deftpower in industry conversations, from first pitch to signed agreement
- Share what CPOs and flex buyers actually need with Product, so you keep selling something we can deliver
- Explore flex buyers (BRPs, aggregators, energy traders) as a next market for aggregated flexibility
- Manage signed accounts together with Account Management, keeping the partnership on track
"Everyone is driven to make customers happy, we don't just work for the sake of working."
- Florian, Team Lead
About you
You know how to get a contract signed with a technical, commercially cautious counterpart. Not just the pitch, the actual negotiation: pricing structures, milestones, mutual commitments. You combine that with enough energy-market literacy to speak credibly about grid constraints, dynamic tariffs and demand charges.
- You have 5+ years of experience in business development, partnerships or commercial negotiation, ideally in energy, e-mobility or a related regulated market
- You understand energy-market and regulatory complexity (grid-operator requirements, balancing markets, BRP relationships) well enough to translate it into a commercial proposition
- You have experience structuring and closing B2B contracts with technical and financially sophisticated counterparts
- You can navigate long, multi-stakeholder sales cycles without losing momentum
- You can build a business case that balances CPO economics with Deftpower's commercial growth
- You can say no to partners, respectfully and with good reasoning
Our values
Drive You love turning ideas into action. You take ownership, push projects forward and get energy from creating solutions that actually work in the real world.
Earnest You do the right thing, especially when no one's watching. You're respectful, honest and reliable, colleagues know they can count on you.
Forward thinking You're curious and not afraid to try new things. You experiment, learn fast and spot opportunities before others see them coming. Calculated risks? You're in.
Transparency You believe sharing is power. You communicate openly, give constructive feedback and make your work visible so the whole team can grow together.
