Using Git and CI/CD pipelines to maintain code quality and support deployments

Working with data transformation, cleansing and standardisation

Supporting modern data architectures including data lakes and data warehouses

Using Terraform / Infrastructure as Code to build and manage environments

Implementing logging, monitoring and alerting across production systems

Working with technologies such as Pandas, Pydantic, Airflow, AWS Glue, Docker, JSON and Parquet

Working alongside data scientists, engineers and multidisciplinary delivery teams

Supporting and mentoring other engineers and sharing technical knowledge

Strong commercial experience with Python

A solid understanding of backend / software engineering principles

Experience working with AWS, Azure or GCP

Experience with Git, CI/CD and automated testing

Knowledge of databases and data processing

Experience building or working with APIs, services or data pipelines
