This is a remote position.

As a Senior Data Scientist at Migo, you will play a key role in optimising our machine learning-driven decision systems, from monitoring and retraining existing models to developing new ones that power automated lending decisions. You will analyse performance data to refine features, select optimal models for different customer segments, and integrate new data sources into our modelling frameworks. Your work will combine statistical rigour with practical problem-solving, leveraging causal inference concepts, A/B testing, and robust ETL pipelines to improve model accuracy and stability. Working closely with engineering and product teams, you will ensure our decision-making systems remain adaptable, data-driven, and effective as we scale into new markets and serve a growing customer base.
