Data Engineer

You will build and look after the pipelines that move data from the client's operational systems into the warehouse, and the data models that everything downstream depends on. Ingestion, processing and modelling, plus the documentation that goes with them. You will also do the analyst work that keeps the numbers honest. 
What you will do 
Profile new sources before you build: databases, APIs, files, open data, structured and unstructured. 
Build, schedule and monitor ingestion and processing pipelines in the tools the client already uses, and extend them where it makes sense. 
Design and build the warehouse models (star schemas, conformed dimensions) that dashboards and machine-learning use cases sit on. 
Put data-quality checks and lineage capture into every pipeline, and keep the conceptual, logical and physical model documentation current. 
Work with business owners to reconcile figures and define KPIs, and help write the monthly progress report. 
What you need 
Strong Python and SQL, used in production 
Spark (Databricks or Hadoop) and BigQuery, and comfort with both data-lake and warehouse patterns 
Hands-on experience with at least two of Talend, Informatica, NiFi and Denodo 
Extracting and capturing changes from MS SQL Server, Oracle, MySQL and PostgreSQL 
Ingesting from APIs, files (SFTP, Excel, CSV) and open data, in batch and streaming 
Dimensional modelling: star schemas, conformed dimensions, slowly changing dimensions, and the ability to document models at conceptual, logical and physical level 
Orchestration, monitoring, retries, data-quality checks and lineage 
Profiling, reconciliation, defining KPIs with business users 
Good to have 
dbt, Airflow, Dataflow, Iceberg
