We are working exclusively representing a specialized IT-Consultancy in Nürnberg known for their "Engineering as a Vocation" mindset. They arent a typical "body-shop" agency; they are a small, elite squad of experts who build and run mission-critical systems for German federal agencies and high-security sectors. We are looking for a Senior Backend Engineer who wants to stop "ticket-pushing" and start taking true Architectural Ownership. You will be building cloud-native platforms where stability, zero-trust security, and high-availability are the baseline requirements, not afterthoughts. The Technical Challenge Modernize & Scale: Transitioning legacy-critical systems into high-performance, Cloud-Native environments. Complex Backend: Leveraging Java (LTS) and Spring Boot/Quarkus to handle sophisticated business logic and high-security data flows. Platform Ownership: You aren't just writing code; you are managing the lifecycle using Kubernetes, Helm, and FluxCD/ArgoCD. Clean Architecture: Applying CQRS, Event-driven patterns, and AOP to ensure systems are modular and maintainable. Observability: Taking responsibility for system health via OpenTelemetry and Prometheus. Who You Are The Veteran Developer: You have 5 years of deep Java/Spring experience. You understand what happens "under the hood" of your frameworks. K8s Proficient: You have integrated services into live Kubernetes clusters and understand the "Ops" in DevOps. Security-Minded: You understand the weight of working on KRITIS-relevant (Critical Infrastructure) projects. Consultative Mindset: You enjoy solving complex problems and can communicate technical decisions clearly. Language: Professional fluency in German (C1) is mandatory due to federal project requirements. USP Elite Environment: Work in a 1-10 person expert team where your engineering decisions carry weight. Purpose-Driven Work: Projects that actually matter for the public infrastructure of Germany. Growth: A culture that invests in deep-tech training and rewards technical excellence over "hours sat at a desk." Transparent Process: We offer a fast, 3-step interview process (CV Tech Chat Fit Chat) with no "coding homework" fluff.
