• Build systems that enable self-service analytics and pave the way for data science applications across our businesses
• Monitor performance metrics for how Data is produced and consumed, and respond to Data incidents.

What we’re looking for

• Experience building, designing, refactoring or optimising data lakes and data warehouses from a variety of data sources using data modelling techniques
• Experience in Building Extract Transform and Load (ETL) pipeline (streaming / batch) using MPP frameworks (Spark, Beam, or other)
• Experience in orchestrating complex pipelines using Airflow, Dagster or other
• Proficiency in one or more programming languages: Python, Java, GO or other
• Experience with AWS or GCP and their products (S3, GCS, Kinesis, Pub/Sub, Lambda/Cloud functions, DataProc)
• Experience with one of the main databases for analytics (Redshift, BigQuery, Snowflake or other).

Nice to have

• Experience modelling and transforming data from event collection to report curation, especially for e-commerce or affiliate businesses
• Experience building production‑grade ML pipelines
• Experience using infrastructure as code (Terraform, Cloud Formation, or other)
• Experience using CI/CD principles.
