MEET AVIOBOOK

AvioBook is a global leader in cutting-edge software and unique hardware for the aviation industry. We revolutionised the Electronic Flight Bag (EFB) market with a product designed by pilots, for pilots. Today, we keep building smart, user-centric solutions that make airlines more efficient and simplify work for flight crews and operational teams.

For our HQ in Hasselt, we're looking for an experienced Data & AI Engineer who wants to build something from the ground up.

How you'll work

You'll collaborate closely with Product Engineering, Operations and the teams managing data ingestion to understand their data and use cases and to ensure data reliability at the source. Together with our Compliance team, you make sure our data is governed the right way.

You'll package and hand off trained models to production, and work with Product Engineering to get them implemented and serving our customers.
