We provide the best, most complete, and most accurate real-time flight-tracking service and are proud to have built a wide variety of successful products on this foundation that have become central to the aviation industry at large.

The Aviation Insight group in Engineering is responsible for delivering real-time and historical insights from our data. We do this through streaming data processing and fusion to generate our single source of truth, which we then use to train our predictive models. FlightAware's Predict crew builds state-of-the-art machine learning systems that leverage years of historical data and hundreds of millions of examples in order to build models for computing runway landing times, gate arrival times, and more. The results of these models power the FlightAware Foresight product suite, which streams live predictive aviation data to major customers in the industry.

As a Machine Learning engineer on our Predict crew, you will be building our next generation of Machine Learning models that will become new Foresight products, improving our existing models, and through this work, improving the operational efficiency of the world’s largest airlines and airports.
