• Partner closely with engineering to productionise models into a TypeScript-led backend

• Coach and mentor engineers and data scientists on data, modelling, and ML practices

Technology Environment

• AWS(Airflow / MWAA)

• Python for analysis and modelling

• JavaScript / TypeScript in the product layer

• SQL for analytical workflows

• Optional but valuable: S3, Glue, Athena, IAM, SageMaker

How This Role Actually Operates
