Big Data Engineer

Big data? That’s peanuts for you! With your mega knowledge of Spark, Scala and Kafka Streams, you convert huge data flows into value for customers and shareholders. This means you are able to steer company decisions and boost customer experiences.


As a leading telecommunications company with its two feet in the digitization of our society, Telenet is eager to bring aboard (big) data-minded personalities that share our passion for turning tremendous amounts of data into value for our customers and shareholders through real-time, data&insights-driven product, service and business innovation. We are looking for a Big Data Architect to contribute to this process by shaping big data architecture, data governance, and data-democratisation within Telenet. 

If this sounds like a nice proposition, here’s what you should have in store for us, and what we will have in store for you…


  • Define and evangelize the short- and long-term vision on Big Data architecture in light of the increasing strategic importance and value of data within the company.
  • Strike the right balance in the way data governance and information architecture is conducted for small- and large-scale data assets (i.e. level of automation, level of detail, coverage, long-term vs short-term focus, cost).
  • Identify opportunities for unlocking business value from (integrating) Telenet’s data sources cross-departmentally.
  • Collaborate with IT security and legal/compliance teams for similar deliverables on data security, privacy (GDPR) and compliance front.

  • Proactively identify techniques that make our data assets easier to use or find.
  • Democratise access to (large-scale) information assets for business users.

  • Big Data technology:  You are experienced in existing and upcoming Big Data technologies (Hadoop, Spark, Kafka, Flink, Cassandra, ELK, ...) and continuously keep in touch with new evolutions in the big data ecosystem.
  • Business acumen: You are able to quickly grasp new business processes and have an aptitude for identifying the best ways to improve or enable those, using data.
  • Visualisation: You know how turn data into insights by using the right, compelling visuals, underpinning your key message.
  • Data ethics: With great power comes great responsibility. Privacy and ethics are top of mind.
