About Belsimpel

Who we are
Since its foundation in Groningen in 2008, Belsimpel has become a big part of the telecom market as a tech company. With a close-knit team of over 500 motivated, enthusiastic and honest students and professionals, including over 50 (business) development colleagues, we go above and beyond every day to change the Mobile World. We’re not a provider, nor a store or search engine. We’re a way of life, a Method™ to help customers find their perfect mobile telecom match.

What we do
As Belsimpel has grown a further 50% in 2018 (turnover of 200 million in 2017), more and more customers are visiting our website. More customers means higher traffic and with a million visitors each month, we’re generating an unbelievable amount of data. As a progressive company, we extract valuable information from the available data to improve the efficiency of our website and marketing efforts. That’s why our Data Driven Developers and Marketers work hard every day to optimise the conversion. As Data Scientist, you’ll work with large data sets every day. Developing smart solutions makes us feel like winners!

What we can offer
We offer multidisciplinary challenges that require solving complex puzzles using theory from your Econometrics & Operations bachelor’s or master’s degree. As Belsimpel is constantly evolving, you’ll be able to grow within the company. This means you’ll face a steep learning curve and your work will directly impact the entire company.

Love solving complex puzzles every day and want to be part of our winning spirit? Join us as full-time Business Developer or Data Scientist, write your final project at Belsimpel or join us as a part-time colleague during the final phase of your degree to work on smaller projects that bring the future a step closer.

Alumnus of VESTING at Belsimpel
Efficiency is one of the most oft-repeated concepts in Econometrics and one of the most important principles for Business Developers. At Belsimpel, it’s my job to find and eliminate inefficiencies by devising and executing improvements. On the one hand, this task is quite challenging, as it affords me the opportunity to apply knowledge gained during my studies. On the other hand, the experience is incredibly valuable, as you’ll need to keep an eye on the bigger picture. Developing a helicopter view is absolutely essential. One of the best things about working for Belsimpel is being given the opportunity to have an impact on the company from day one if you put forward great ideas.
Belsimpel also knows how to have a good time. You can regularly attend drinks and you’ll always find a colleague who’s up for a game of table tennis, table football or pool during your lunch break.
