BI Developer
Craft data pipelines and reporting systems to empower business decisions.
What is a BI Developer?
BI Developers build and maintain the infrastructure that transforms raw data into actionable insights. They design ETL processes, develop data warehouses, and create interactive dashboards, enabling stakeholders to monitor key performance indicators and make data-driven decisions.
You spend most days building, validating, and monitoring pipelines, manipulating stored data for analysis, and clarifying user requirements for reports. Between deployments you confer with systems analysts and engineers to design interfaces, test and validate ETL jobs, and prepare status reports. Work is largely sitting at a terminal, switching between SQL, data models, and stakeholder email to keep dashboards reliable and consistent.
