• Designing and implementing scalable data architectures on GCP, primarily using BigQuery and Cloud Composer.
• Developing and maintaining reliable, recoverable ELT/ETL pipelines.
• Building analytics-ready data models with dbt, including staging, warehouse and mart layers.
• Implementing data documentation, testing and quality checks.
• Setting up and maintaining CI/CD processes with GitLab, including quality gates and promotion across environments.
• Managing cloud infrastructure with Terraform, including cloud resources, IAM permissions and relevant networking dependencies.
• Developing Python components for data ingestion, orchestration, data quality checks and automation.
• Taking ownership of production operations, including monitoring, alerting, incident response, cost management and performance optimisation.
• Working closely with Analytics Engineers, AI Engineers and business stakeholders to translate requirements into robust data products.

Technical environment ###

• GCP: BigQuery, IAM, Cloud Composer and Airflow
