We are looking for an experienced Solution Architect to own the end‑to‑end architecture of a modern middleware platform. The role covers designing and evolving a distributed, event‑driven stack that integrates off‑the‑shelf components such as ELK, Kafka and Keycloak with custom microservices‑based backend and SPA/frontend applications. Solid hands‑on experience in defining and enforcing strict non‑functional requirements (security, performance, scalability, high availability) and translating them into concrete architectural patterns, capacity models and deployment topologies is essential.

Role And Responsibilities

• Translate business requirements into end‑to‑end architectural designs aligned with enterprise, IT and regulatory strategy.
• Engage with customers and stakeholders, presenting and defending architectural decisions.
• Shape Enterprise Architecture roadmap and support change initiatives and innovation.
• Lead cross‑domain architectural work and mentor delivery teams to ensure consistent execution.
• Define and own EA strategy across Business, IS and IT.
• Design architectures using API management, microservices and container platforms (Kubernetes).
• Ensure solutions meet SLAs and critical non‑functional requirements (security, performance, scalability, availability).
• Apply industry standards (TOGAF, ArchiMate, UML) and work within Agile/DevOps environments.
• Embed security‑by‑design (IAM, authN/authZ, compliance) and design for public, private and hybrid cloud landscapes.
