ryd

DEINE AUFGABEN Der Systemarchitekt bei ryd ist verantwortlich für die Architektur der Integrationsplattform. Sie entwerfen die technische Grundlage, die es ryd ermöglicht, sich mit Dutzenden unterschiedlicher Partner und Ökosysteme zu verbinden – konsistent, sicher und schnell. Sie arbeiten an der Schnittstelle aller Teams und aller Geschäftsbereiche. Sie sind die Person, die sicherstellt, dass jeder Integrationsansatz unter einer einzigen, erweiterbaren Architektur vereint wird, die bei Bedarf konfigurierbar ist. Sie berichten an den CTO und arbeiten mit Lösungsarchitekten, dem leitenden KI-Experten, den Leitern der Entwicklungsteams und dem Produktmanagement zusammen. Kernaufgaben 1. Entwurf der einheitlichen Integrationsplattform * Definieren Sie den Katalog der Standard-Integrationsansätze – APIs (REST, GraphQL, gRPC), Webhooks, WebView-/iframe-Einbettung, SDK-basierte Integration, OAuth-basierte Authentifizierungsabläufe, dateibasierte Batch-Integration. * Stellen Sie sicher, dass jeder Ansatz erweiterbar und konfigurierbar ist – Partner können Parameter (Authentifizierungsmethoden, Datenfelder, Ereignisauslöser) anpassen, ohne dass Codeänderungen an der Kernplattform erforderlich sind. * Entwerfen Sie die Architektur für das Partner-Onboarding – von der Registrierung über die Sandbox bis zur Produktion, mit klaren Meilensteinen, automatisierten Tests und Self-Service-Funktionen. * Entwerfen Sie die Datenflussmuster – wie Partnerdaten durch den Kafka-Ereignisbus von ryd, die BigQuery-Analytik und interne Dienste fließen, wobei Konsistenz, Idempotenz und Beobachtbarkeit bei jedem Schritt gewährleistet sind. 2. Teamübergreifende Koordination * Arbeiten Sie mit den Backend-Teams zusammen, um sicherzustellen, dass die Integrationsplattform die NestJS-Mikroservices, das Kafka-Event-Streaming und die Datenbanktechnologien von ryd effektiv nutzt. * Arbeiten Sie mit den Frontend-Teams zusammen, um einbettbare UI-Komponenten, WebView-Abläufe und Dashboards für Partner zu entwerfen. * Arbeiten Sie mit der Qualitätssicherung zusammen, um Strategien für Integrationstests zu definieren – Sandbox-Umgebungen, automatisierte Tests der Partnerabläufe, Vertragstests. * Arbeiten Sie mit dem DevOps-Team zusammen, um sicherzustellen, dass die Plattform auf Kubernetes und GCP skalierbar ist und über angemessene Überwachungs-, Warn- und Kostenmanagementfunktionen verfügt. * Arbeiten Sie mit den Produkt- und Geschäftsbereichen zusammen, um Partnersegmente zu verstehen, Integrationsansätze zu priorisieren und die Weiterentwicklung der Plattform an den Geschäftszielen auszurichten. * Arbeiten Sie mit dem Lead AI Practitioner zusammen, um sicherzustellen, dass die Plattform KI-optimiert ist – KI-lesbare Dokumentation, KI-testbare Abläufe, KI-gestützter Partner-Support. 3. Alle Geschäftsbereiche verstehen * Flottenmanagement – wie Flottenunternehmen Fahrzeuge, Fahrer, Tankkarten, Ausgaben und Berichterstattung verwalten. * Zahlungsabwicklung – PCI-DSS-Konformität, Zahlungsgateways, Abrechnung, Kontenabstimmung. * Mobilitätsdienste – Kraftstoff, Laden von Elektrofahrzeugen, Autowäsche, Parken, Maut. * Fintech-Integrationen – wie Bank- und Finanzplattformen Dienste von Drittanbietern in ihre Apps einbinden. * E-Commerce-Integrationen – wie E-Commerce-Plattformen Händlern Zusatzdienste anbieten. * ERP-/Buchhaltungsintegrationen – wie Unternehmen wie SAP, Datev oder Lexware Transaktionsdaten nutzen. * OEM-Integrationen – wie Automobilhersteller Zahlungsfunktionen einbinden  * Kostenmanagement – wie Dienste wie Pleo, Moss oder Circula Flottenausgaben verarbeiten und kategorisieren. 4. Die Partnererfahrung gestalten * Entwerfen und erstellen Sie eine Partner-Testumgebung (ähnlich wie https://partners-demo-frontend.web.app/partners/demo/webview-launcher), in der potenzielle Partner Integrationsansätze interaktiv erkunden können. * Verantwortung für den ryd-Portal-Integrationsleitfaden übernehmen – sicherstellen, dass die Dokumentation klar, aktuell und per KI durchsuchbar ist. * Selbstbedienungsmanagement entwerfen – Partner können ihre Integration konfigurieren, Analysen einsehen, API-Schlüssel verwalten und Probleme beheben, ohne den ryd-Support kontaktieren zu müssen. * KI-gestützte Unterstützung für Partner entwerfen – Chatbots, die Fragen zur Integration beantworten, KI, die Konfigurationsänderungen vorschlägt, KI, die Integrationsprobleme analysiert. 5. KI in die Architektur einbetten * Wenden Sie KI-Architekturmuster (RAG, Agenten, Pipelines, Orchestrierung) auf die Integrationsplattform an. * Entwickeln Sie KI-gestützte Onboarding-Abläufe für Partner – die KI analysiert die Systembeschreibung eines Partners und empfiehlt den besten Integrationsansatz. * Implementieren Sie KI-gesteuerte Fehlerbehebung – erkennen Sie Integrationsanomalien, schlagen Sie Lösungen vor und automatisieren Sie gängige Lösungswege. * Stellen Sie sicher, dass die Wissensdatenbank der Plattform für die Nutzung durch KI strukturiert ist (gemäß den Standards des Lead AI Practitioner). * Nutzen Sie KI-Tools (Claude Code, Cursor, Copilot) in Ihrem eigenen Workflow – demonstrieren Sie, wie eine KI-beschleunigte Architektur aussieht. 6. Steuerung und Weiterentwicklung der Plattform * Führen Sie Architekturentscheidungsprotokolle (ADRs) für alle wichtigen Plattformentscheidungen. * Definieren und setzen Sie nicht-funktionale Anforderungen durch – Leistung, Sicherheit, Skalierbarkeit, Zuverlässigkeit, Beobachtbarkeit. * Überprüfen Sie die Integrationsentwürfe der Lösungsarchitekten – stellen Sie sicher, dass diese mit dem einheitlichen Ansatz der Plattform übereinstimmen. * Sammeln Sie Feedback von Lösungsarchitekten und Partnern – verbessern Sie die Integrationsansätze kontinuierlich. * Verwalten Sie technische Schulden – jede Integration, die nicht zur Plattform passt, ist eine zukünftige Schuld. Das verhindern Sie.
