Let machines do the heavy lifting while you focus on growth.

Are you fascinated by how Google and AI search engines decide what people do and don’t get to see? Would you rather build a smart system than do a task ten times by hand? At JKC, you’ll work on improving the online visibility and growth of clients throughout the Netherlands, using automation, prompt engineering, and AI as your main tools.

You don't need a background in marketing. A technical perspective is just as welcome. What matters is that you understand how algorithms work and know how to continuously optimize them.

Here's what you'll be doing

You’ll work on driving online growth for clients, but not by doing everything manually. You’ll build smart processes, gain a deep understanding of search algorithms, and leverage AI to work faster and more effectively. Specifically, you’ll be responsible for:

  • Understanding how Google's algorithms and AI search engines work, in order to ensure that our clients' websites and online stores are as easy to find as possible
  • Optimizing for discoverability in both Google (SEO) and AI search results (GEO)
  • Prompt engineering: Training AI models to produce useful and reliable results
  • Automating marketing and business processes with tools like Cursor and AI models such as Claude, ChatGPT, and Gemini
  • Develop, implement, and continuously optimize strategies based on data
  • Engage customers in what you do by explaining technical topics in plain language

We’re not satisfied until the customer is, and that’s how you should think, too.

Who are we looking for?

Your background can be in business (Marketing Management, Business Economics, Business Administration) or in technology (Computer Science, Data Science, AI, or similar). What matters is your way of thinking. We’re looking for someone who:

  • Has a college-level (HBO/WO) level of thinking, with an affinity for data, technology, or marketing
  • Thinks analytically, is curious, and enjoys figuring out how things work under the hood
  • I get excited about AI, automation, and beating an algorithm
  • Would rather build a system than repeat a task ten times
  • Can clearly explain technical matters to customers without using technical jargon
  • Is critical of their own work and keeps testing until it's just right
  • Helder communicates in Dutch and can get by in English

Have you built or automated anything you're proud of? Send it in.

About JKC

Founder Justin started JKC in 2017 as a hobby. What began as a passion project that took on a life of its own has grown into a professional web agency with offices in Eindhoven and Rotterdam, more than 300 satisfied clients, and a young, close-knit team that enjoys coming to work every day.

We combine design, development, and online marketing all under one roof. No separate teams working at cross-purposes, but a single team dedicated to delivering results. We’re curious, skilled in our craft, and transparent in our approach. We say what we do, and we do what we say. A deal is a deal.

Our clients range from local small and medium-sized businesses to larger organizations such as Amsterdam UMC, the City of Rotterdam, and High Tech Campus Eindhoven. We’re proud of them all. Because whether it’s a baker launching his first online store or an organization that welcomes thousands of visitors a day, we always strive for the same result: online visibility and real growth.

We’re far from done. JKC is expanding internationally and is constantly evolving. When you join us, you won’t be joining a stagnant company, but a team that’s moving forward.

We often get these questions


We follow an efficient and personalized process designed to determine whether there is a mutual strategic fit. After you submit your application, we’ll conduct an initial screening, followed by a targeted phone consultation to discuss the details of the role.

Next, we’ll host a virtual introductory meeting to explore your expertise and our vision in greater depth. The process concludes with an in-depth discussion where we’ll define the terms of our collaboration and your growth path within the organization. We don’t believe in drawn-out bureaucracy, but rather in honest communication and decisive action.

We believe that a healthy work-life balance is the foundation of high performance. Our company culture supports working from home part-time, with one day per week being the standard for full-time employees.

At the same time, we place great value on the synergy that comes from being physically present at our hubs. The speed at which we innovate, brainstorm, and grow together reaches its peak when we collaborate in person on complex challenges. At JKC, you’re not choosing a typical office job, but an environment where collective intelligence and personal commitment are the norm.

At JKC Media, you are in charge of your own career path; we help you accelerate your growth. In our high-performance culture, we don’t focus on rigid job descriptions, but on potential, execution skills, and ambition.

Because we operate at the intersection of complex web technology and AI, you’ll have the opportunity to specialize at the cutting edge of the market. Strong performance and strategic ownership directly translate into greater responsibility and new challenges. Whether you choose to dive deep as a technical specialist or aspire to a leadership role within our international hubs, at JKC your role grows alongside the impact you make.

While most agencies operate as providers of individual services, JKC acts as the architect of your comprehensive growth engine. We bring together strategy, high-end design, development, and AI marketing under one roof. Our edge lies in the fusion of human expertise with technological innovation: we don’t use AI as a gimmick, but as a catalyst for unprecedented efficiency and data-driven results.

In a fast-paced market, we prioritize technical expertise and strategic clarity. No empty promises—just tangible execution. We translate complex technological challenges into clear business cases, taking full responsibility for the end result. At JKC, you’re not just investing in a website—you’re investing in a scalable digital foundation that sets the standard in your industry.
