## About the Role

 * Semi-Structured Data (NoSQL equivalent): Working knowledge of handling JSON/JSONB data types within PostgreSQL.
 * Performance & Integration Awareness: Basic familiarity with indexing strategies, query execution plans (EXPLAIN), or connecting PostgreSQL to wider cloud environments (e.g., Azure integration or Foreign Data Wrappers).

## Description

We are looking for a Junior PostgreSQL Developer to join our data streams. In this role, you will play a critical part in bridging the gap between data analysis and database engineering. You will collaborate closely with data analysts to design, optimize, and maintain the database structures required to drive our public sector data streams, with a heavy focus on backend database development.
Core Responsibilities

 * Data Mapping & Transformation: Focus on core database tasks, specifically writing clean, efficient queries to map and transform raw data into structured relational tables.
 * ETL & Pipeline Development: Assist in developing database-level ETL (Extract, Transform, Load) processes, using PostgreSQL to clean, aggregate, and prepare data for analysis.
 * Cross-Functional Collaboration: Collaborate closely within paired streams to ensure the database layer effectively supports analytical and reporting requirements.
