• Entwicklung innovativer Features und Weiterentwicklung der Web-Plattform • Enge Zusammenarbeit mit dem Business-Team • Umsetzung von Features im Team, sauberer Markup und effizienten Code • Teilnahme an Code-Reviews und Verbesserungen • Arbeiten mit modernen Technologien

• Liderar la gobernanza de arquitecturas distribuidas en proyectos de escala masiva • Asegurar la resiliencia y dominio del SDLC en cada solución internacional • Colaborar con equipos globales para implementar las mejores prácticas

• Technical Leadership and Cockpit Architecture: Act as the technical lead (Tech Lead) of the Application Squad, ensuring cohesion between the UI engine (React/TypeScript) and our backend (Kotlin/Spring Boot). You will be responsible for defining API contracts and the data-fetching strategy for our high-density planning screen. • BFF (Backend For Frontend) development in Kotlin: Design and implement microservices in Kotlin (K2) + Spring Boot hosted on Amazon EKS. This BFF will not be a simple request proxy; it will perform intelligent data aggregation, token validation, and manage continuous bidirectional connections (WebSockets/SSE) for real-time screen updates. • Transient State Engineering (Draft Store): Model and implement a "Draft" architecture (What-If scenarios) using Amazon DynamoDB (On-Demand). You will ensure that thousands of cell edits made by planners are saved to hot cache in milliseconds without overloading the primary relational database. • Asynchronous Orchestration to Avoid Timeouts: Eliminate blocking microservice anti-patterns. You will delegate coordination of long-running business flows (such as cycle-close consolidation) to AWS Step Functions, using advanced callback patterns (.waitForTaskToken) and native integrations to connect the frontend to heavy GCP processes and the rules engine, avoiding idle pods. • Full-Stack Synergy: Work closely with the Front-End Specialist. Although your focus is server engineering, you must understand the React lifecycle, the importance of DOM virtualization, and how to structure responses (JSON/Protobuf) to enable memoization and avoid blocking the browser’s main thread. • Quality, CI/CD and Governance: Lead engineering best practices within the Squad. Ensure robust automated test coverage (unit tests, integration with Testcontainers, and contract testing via E2E), enforce rigorous code reviews, and operate the Continuous Deployment pipeline (Azure DevOps / GitHub Actions) based on our internal platform (Backstage).
