About THEO Technologies

THEO is a scale-up on a mission to change the way the world streams video over the internet. Our flagship product is THEOplayer which enables our customers to stream videos on all kinds of devices and platforms (Web, Android, iOS, Roku, ...). Chances are high you have used it already. Maybe watched a video on Vrt Nu, Yelo or CNN? That's all THEOplayer! It offers a variety of features like content protection, advertisements, analytics and so on. THEO also has an innovation team which invented the HESP streaming protocol. It is specifically designed for ultra low-latency streaming that other protocols just can't offer at the same scale.


The role

We are looking for an experienced software developer to join the team. This small team of very experienced and passionate engineers builds an entire streaming pipeline leveraging our HESP protocol. The main focus is the backend, so ingesting data from customers, transcoding it to different qualities, packaging the data and distributing it to the end customers using a CDN and of course THEOplayer. The product is built on common technologies like Typescript, Node, Python, Docker, Kubernetes, Helm, ... But since it really pushes the state of the art, the team needs to be creative and come up with solutions for problems that just haven't been tackled by the industry. The team also has a lot of freedom and responsibility. Everyone works closely together and the architecture, technologies used, ... are all decided by the team. We really believe in the 'the right tool for the right problem' approach.


About you

  • 3+ years of experience as a software developer.
  • You have a creative and problem-solving mind.
  • You write clean code and like to help in designing the architecture.
  • Strong interest in learning.
  • Strong interest in media.
  • You're a team player that knows when to work together and when to fly solo.
  • Tons of energy, passion, humor and enthusiasm.


What we offer

  • A competitive salary with plenty of extra benefits;
  • The opportunity to work for an exciting scale-up with a stimulating working environment, which values action, courage and curiosity with stunning and passionate colleagues;
  • Personal development: a chance to grow and to develop your strengths while working with many bright minds and to get in touch with the cutting edge of online video;
  • A hybrid working policy with flexible working hours;
  • Regular and fun team activities.
