We're looking for a seasoned Full Stack Consultant to join our client's team and help build a data-driven web platform that supports policy decision-making in a highly complex regulatory environment. This role sits at the intersection of software engineering, large-scale data processing, and analytical decision logic, offering the chance to work on a solution with real societal impact—without exposing any client or program identity.
The role
Our client is developing a new web application designed to analyze large datasets, generate reproducible snapshots, and apply complex business and regulatory rules to support long-term planning and reporting. As a Full Stack Developer, you will translate functional analyses into robust technical solutions, contributing to both backend and frontend development within a modern, cloud-connected architecture.
The platform processes high volumes of structured data (such as CSV inputs), performs analytical workflows and projections, and applies decision logic to produce traceable and auditable outcomes. The technical landscape includes a Java Spring Boot backend, a web frontend, a PostgreSQL database, and integrations with cloud-based data processing services.
