Du kombinierst starkes Product Sense mit Hands-on Engineering und baust agentische Systeme, die in der Praxis zuverlässig, sicher und skalierbar funktionieren.\nWichtig: Keine disziplinarische Personalverantwortung. Du führst über Expertise, Standards und Ownership.\nDeine Aufgaben\nFullstack-Execution: Du entwickelst UI und Backend-Services in unserem Stack (TypeScript/Angular) und baust robuste APIs sowie Integrationen.\n\nOutcome Focus: Du verantwortest messbare Ergebnisse. Du definierst Success Metrics, Baselines und Guardrails - bei dir zählt Impact vor Output.\n\nAI Strategy: In enger Zusammenarbeit mit Product identifizierst du High-leverage Workflows, die wir durch intelligente Agents automatisieren.\n\nIterative Shipping: Du übersetzt unscharfe Probleme in iterative Releases (MVP → v1 → Scale) und triffst smarte Trade-offs zwischen UX, Risiko und Engineering-Qualität.\n\nAgentic Architectures: Du designst und implementierst Architekturen für AI-Agents - von Tool Use und Orchestrierung bis hin zu Kosten- und Latenz-Kontrolle.\n\nRobust Evaluation: Du etablierst Testsets und Regression-Suites, um Quality, Safety und Reliability unserer AI-Features in Production sicherzustellen.\n\nEngineering Standards: Du setzt die Benchmarks für Testing, Code-Qualität, CI/CD und Skalierbarkeit in einer Cloud-Umgebung (AWS).\n\nTech Leadership: Du hebst das Team-Level durch Design Reviews und Pairing, schaffst Orientierung und setzt Standards für AI-Reliability.\n\nMentoring & Hiring: Du unterstützt das Wachstum des Teams durch Mentoring und bringst dich aktiv in unseren Interview-Prozess ein.\n\nDein Profil\nProduct Shipper: Du hast eine nachweisbare Historie darin, Customer-facing Produkte End-to-end (UX + Backend + Ops) erfolgreich zu releasen.\n\nFullstack Pro: Du bist technisch tief in unserem Stack (TypeScript + Angular) verwurzelt.\n\nProduct Mindset: Du balancierst technische Exzellenz mit Business Outcomes und triffst pragmatische Entscheidungen für das Produkt.\n\nProduction Experience: Du bist sicher im Umgang mit AWS, Docker, CI/CD und bringst ein ausgeprägtes Reliability-Mindset mit.\n\nAgentic Know-how: Du hast Hands-on Erfahrung mit Agentic Coding oder Workflows (LLMs, die planen und Tools nutzen).\n\nCollaboration: Du arbeitest zuverlässig, pragmatisch und absolut teamorientiert über alle Funktionen hinweg.\n\nLanguages: Du kommunizierst sicher auf Englisch.\n\nBonus Points (Nice-to-haves)\nAI Track Record: Du hast bereits AI-Produkte vom ersten MVP bis zur breiten Adoption in Production begleitet.\n\nMessaging & Data: Erfahrung mit Pub-Sub Systemen (RabbitMQ, SQS) sowie MongoDB Performance und Data Modeling.","description_format":"text","description_chars":2817,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"German","level":"Advanced
