Johannesburg, South Africa | Posted on 21/05/2026 Build independent, composable micro frontend modules that integrate into a governed portal shell using runtime composition. Build domain-aligned, event-driven backend capabilities that support deterministic decisioning, versioning, and replay ability. Responsibilities Develop micro frontend modules (widgets, panels, tabs) using React and Next.js Integrate via Module Federation and platform extension points Use platform SDK for context, events, telemetry and messaging Ensure compliance with platform contracts and governance rules Build responsive, accessible UI aligned to design system Maintain performance budgets and emit telemetry Own and implement domain capabilities (e.g. Party, Quotes, Pricing) Design APIs, events, and data ownership boundaries Implement event-driven architecture (commands, events, projections) Ensure full versioning discipline across APIs, events, and rules Integrate systems via contracts, not direct coupling API Gateway and BFF patterns Open Policy Agent (OPA) Schema Registry and contract testing Temporal or workflow engines Requirements Matric and a Tertiary Degree Front End Required Skills Module Federation or microfrontend architecture experience Experience with OpenTelemetry (frontend) Experience with design systems and component libraries Back End Required Skills .NET Core (preferred) or equivalent backend platform PostgreSQL and Redis Event-driven architecture and event sourcing concepts #J-18808-Ljbffr
