We develop everything ourselves.
Everything!

Yearly, Belsimpel.nl processes more than half a million transactions with a system that we developed ourselves.

Creating order from chaos

Customers have a hard time trying to find exactly what they want in the telecom jungle – with over 17 million price points, who wouldn't? To solve this, Magento implementations or standard Microsoft solutions unfortunately do not cut it. Let alone trying to produce real-time price calculations…

This is why we, at Belsimpel.nl, decided to build our own system to create order from this telecom chaos. Our website, with over a million monthly visitors, is just the interface of the complex system we have behind the scenes. Back here, we have all of the mouth-watering code, hardware and the people supporting it – without any third party interference. This lets us provide our customers with the unparalleled service when it comes to speed and reliability.

Does the idea of improving our own Customer Relationship Management (CRM) software, which is used by over a hundred customer support colleagues, spark your interest? Or do you believe you could make our Warehouse Management System (WMS), which is used to process hundreds of thousands of orders, even more efficient? If so, you've come to the right place! Here at Belsimpel.nl, you really make a difference.

Belsimpel = 555 phones × 473 phone plans × 65 bundles = a lot

That's why we build everything ourselves.

Our team

Our team is composed of a mix of intelligent colleagues who graduated recently and highly experienced developers who have been with us for years. Most of your colleagues have technical degrees and have turned their passion into a full-time career at Belsimpel.nl.

Will you join our team? We love new colleagues! Your critical but respectful eye and spirit keep us alert so we can improve daily.

Meet our Developers

Nanne

Senior Developer

My career as a developer at Belsimpel.nl started the moment that the company had outgrown Jeroen and Jeroen's student dorms. At this point, we decided to keep developing our code ourselves. I knew Jeroen from university and my job interview consisted of nothing more than a cup of coffee, after which I started working at the development 'department'. Initially, all I did was build and maintain our website, but as the company grew, the workload also increased. Nowadays, we have complete control over the code behind the systems for our warehouse, customer service, financial departments and more! The best part about my job is working on interesting projects that we develop, implement and expand ourselves. When you see the results of our work in action, you can clearly see how we contribute meaningfully to Belsimpel as a company. Besides my work at Belsimpel.nl, I also work on several nerd projects of my own in my spare time. This ranges from software projects to learn new languages to automating parts of my home, just for the sake of it. These nerd projects sometimes even help to dream up great ideas that we are able to implement at work. And vice versa, the pool table skills that I pick up in my break are transferrable to the bar that night :)

Joshua

Senior Developer

My name is Joshua Peper. I am the lead developer of the App team at Belsimpel.nl, where we design and develop all of Belsimpel's apps. Our coolest projects are often even used by other companies, like our ID verification artificial intelligence project. How I ended up working at Belsimpel.nl? Well, that's a bit of a long story. The gist of it is that the company I owned with my business companion (Peperzaken) was taken over by Jeroen and Jeroen in 2016, as there was a lot of app-related work for us to pick up. By now, we're fully integrated into the company. In my spare time, I often visit tech-related meetups, go for a jog or mess around with hardware that is designed to read the contents of my physical mailbox from a distance, for example. The best thing I ever did at Belsimpel.nl? That's a difficult question, but I'm going to have to go with our artificial intelligence project (for ID verification). This entire project was quite a challenge, but we ended up gaining so much invaluable knowledge. The most exciting thing was probably the launch of our first app at Belsimpel.nl: In Control. You never know what the response is going to be like, and the feedback in the Play Store and App Store can be brutal.

Niels

Front-end Developer

My name is Niels, and I'm a Front-End Developer at Belsimpel.nl. This means that I'm responsible for providing our customers with an intuitive website that can be navigated without running into any hitches or glitches. I do this by, for instance, optimising the layout for different display resolutions. I am also responsible for all emails that you might receive during or after your order process, as well as the automatically generated PDFs, such as contracts and invoices. I completed my education in Brand & Design Management in 2013 and started looking for interesting positions soon after. The Belsimpel.nl website mentioned a vacancy for a Front-end Developer position. I applied, and now here I am. Since I started working at Belsimpel.nl, I have worked on a variety of interesting and challenging projects. The most impressive of these was probably our transition into a responsive website. We deconstructed the front-end of the Belsimpel.nl and rebuilt it completely over the course of several months. The goal of this was to ensure that our website performed optimally on all platforms, including phones, tablets, laptops and desktops. In my spare time I enjoy being creative. Sometimes I work on my own websites, but I also like photography, drawing and writing. I'm also crazy about films and series, as well as listening to music. The latter I can even do at the office. Headphones on = work mode.

Patrick

Senior Developer

Hey, I'm Patrick Ratelband (before you ask, I'm not related) and I've been working at Belsimpel.nl as a Back-End Developer for over three years now. Truth be told, I actually work on every part of our entire system. I've worked on everything from the online shopping cart to the back office. A former colleague of mine told me about a vacancy at Belsimpel.nl and told me I should apply. He had done the same for a different position, and had been very positive about Belsimpel since then. So I figured, why not? Within a week I had my interview with Jeroen and about a month later I was my friend's colleague again. What I like about working here is that we work on larger, consistent projects, rather than 'fire and forget' projects. Getting to see your projects grow over time thanks to the work you put in adds significance and comes with a healthy amount of responsibility that I enjoy.

How we work

Our current team consists of about 23 developers who work on different projects in smaller teams. Besides our weekly general meetings in which we sketch the outlines of our projects, you attend team meetings to discuss the finer details of your current project(s). Meanwhile, you are in close contact with our business developers to translate issues from other departments within the organisation into excellent programming solutions.

Important decisions are made together by mutual agreement. Development is one of the core positions within Belsimpel.nl and the most important driver of our growth performance as a company. There is no middle layer; Jeroen & Jeroen are present at all meetings concerning important decisions. No office politics, no project managers who don't understand the business or technologies, no frustration.

You work on your own code independently, but you also work together a lot. Your fellow developers review your code and you review theirs. You are able to be critical, while maintaining a respectful attitude. This way, we keep up a high standard of work whilst picking up valuable knowledge along the way. We push several releases each day. Is your code going live? You are responsible for your own releases, but colleagues are always willing to help if something goes wrong. Constantly putting out your colleagues' fires is not part of the job description.

Notice something that could be improved? We're very open to change. Got an idea to make a piece of back-end code more efficient? We're not afraid to throw out heritage code. Do you have ideas on improving the front-end? We'll add your ideas to the a/b test queue.

We work with a variety of tools, including AWS, Docker, NGIX, PHP7 and Galero.

10.000.000 unique combinations of phones, phone plans and bundles

That doesn't fit in a Magento or Microsoft solution :)

Who are you?

We are looking for bright and passionate colleagues. We expect you to be an incredibly competent programmer, which is why we do not require a lot of prior knowledge of the programming languages we use daily. If you are highly capable, you'll master these in no time. If you are smart, critical yet respectful and enjoy creating complex systems that impact the user-experiences of hundreds of thousands of customers and a team of hundreds of colleagues, we are looking for you to join our team!

You'll get the right gear.

You won't be squinting at a 15" laptop screen. Instead, you have three displays and all the other necessary gear at your disposal to get some serious work done.

Training

As a new member of the Belsimpel.nl development team, you will be placed in an intervision group. Together with an experienced colleague, you will go over common examples of their daily challenges on a weekly basis. You work on identifying these challenges and improve your problem solving skills. You can also take additional courses to develop your skills on a professional level.

Training period

During your first period at Belsimpel.nl, you will get an experienced colleague to turn to when you encounter problems. They will help you understand our codebase and protocols. Don't worry, you'll push your first proper release in no time!
