Improve how models are developed, deployed and operated in production. Work in an Agile Scrum environment and apply practices such as TDD and DDD where appropriate. WHAT WE ARE LOOKING FOR: Hands-on experience across data engineering and applied data science, with the ability to move between exploratory analysis, experimentation and production pipeline development. Strong data analysis skills, including the ability to investigate datasets, interpret findings and explain what they mean for product decisions. Experience working directly with Product Owners to understand requirements, propose experiments and define success metrics. Strong experience building end-to-end production ML pipelines, covering ETL, feature engineering, model training, deployment, serving and monitoring. Proficiency with AWS SageMaker, AWS Glue and AWS Lambda, plus hands-on experience with MLflow, Spark and Airflow.
