About the role
We're looking for a Data Scientist to join Event Time Advancements, the team behind Assaia's flight event time and delay prediction capabilities – especially departure delay prediction and related operational forecasting problems.
This is an applied ML role with end-to-end ownership.



You'll work across the full lifecycle: building datasets and features from evolving event histories, training and evaluating models, and helping keep them reliable in live use together with backend engineering.
A big part of the role is working on dynamic prediction problems rather than one-row-per-case modelling. The same flight or operational event evolves over time through repeated updates, and the model needs to make useful predictions from a changing picture as new information arrives. This makes the work especially interesting for someone who enjoys temporal modelling, sequential reasoning, and building systems that stay useful across multiple decision points.
You should be comfortable making judgment calls on data trust, validation design, and trade-offs, and defending those calls to both technical and non-technical stakeholders.
The team builds and owns its own tooling for dataset generation, trainin
