You know what change control, four-eyes approval, and an audit finding actually mean in practice. * The judgement to work independently and the discipline to document decisions * Genuine interest in applying AI to enterprise problems -- and the instinct to ask how it fails before shipping it * {LANGUAGE -- e.g. English required; German an advantage for stakeholder work} ## Description * Design, build, and maintain backend services in Java and Spring Boot -- REST APIs, microservices, event-driven integrations * Take ownership of existing services: modernise them, harden them, and close technical and regulatory findings * Secure API integrations using OAuth2, OpenID Connect, JWT, and Keycloak * Build and operate services across our hybrid on-prem and Azure landscape, deployed through Jenkins pipelines with all artifacts sourced from our internal Nexus registry * Develop AI-supported workflows -- agentic API automation -- with the security, auditability, and data-protection controls a regulated bank requires * Own quality: automated tests, meaningful observability, and production support for what you build * Work directly with Product, QA, DevOps, Architecture, Security, and Business -- not through layers, * Own architecture decisions for critical backend services, balancing delivery speed with security, resilience, and auditability. * Lead technical design reviews and guide implementation standards across teams. * Mentor engineers through code reviews, pairing, and structured feedback. * Take operational ownership in production: incident leadership, root-cause analysis, and prevention actions. * Drive cross-team delivery by aligning Product, Security, DevOps, and Architecture on technical trade-offs. * Improve engineering maturity: documentation quality, test strategy, observability standards, and secure SDLC practices. Nice to have * Azure services, particularly Azure OpenAI or Azure AI Document Intelligence * Kubernetes, API gateways, monitoring and observability tooling * Hands-on work with RAG pipelines, LLM integration, or agent frameworks (Semantic Kernel, LangChain, or similar) * Messaging and event streaming (Kafka or equivalent) * Experience with securities, payments, or lending domains Tech stack Java · Spring Boot · REST · Microservices · PostgreSQL · Keycloak · OAuth2/OIDC · Docker · Jenkins · Nexus · Azure · Azure OpenAI · Azure AI Document Intelligence
