About the Opportunity
A major European telecommunications group is establishing a new technology hub in Hungary to deliver engineering excellence, on-site support, and knowledge exchange across its European programmes. As Solution Architect / Designer, you will be the technical authority within this hub — bridging business requirements and engineering delivery across a modern Java-based microservices stack in a mission-critical telco environment.
This is a hands-on architecture role: you will design, validate, and guide implementation — not just draw diagrams.
Key Responsibilities
* Own end-to-end solution design across backend, integration, and frontend layers
* Define and enforce architectural standards for Java microservice-based systems
* Translate complex business and product requirements into scalable, maintainable technical solutions
* Design REST API frameworks and integration patterns for internal and external systems
* Oversee PostgreSQL data architecture including JSONB structures and schema design
* Guide and review frontend architecture decisions using Angular and/or React / TypeScript
* Define CI/CD pipeline standards and DevOps integration patterns
* Evaluate and recommend tooling across the Apache ecosystem (Kafka, Camel, etc.)
* Lead technical workshops and design reviews with cross-functional teams
* Collaborate with product owners, developers, and DevOps engineers in agile Scrum/Kanban environments
* Support and mentor senior developers, ensuring architectural consistency across teams
* Contribute to build vs. buy decisions, vendor assessments, and technical roadmaps
* Ensure solutions meet performance, security, scalability, and compliance standards
Required Skills & Experience
* Proven experience as a Solution Architect or Senior Solution Designer in enterprise environments
* Deep expertise in Java (Java 21 preferred) and Spring Boot microservice architecture
* Strong REST API design and integration experience — internal and third-party systems
* Solid PostgreSQL knowledge including schema design and JSONB
* Frontend architecture experience: JavaScript/TypeScript with Angular or React
* Experience with Apache ecosystem tooling (Kafka, Camel, or similar)
* CI/CD pipeline design: Maven, Jenkins, GitLab CI or equivalent
* Containerisation and orchestration: Docker, Kubernetes, Helm
* Strong understanding of security, performance, and resilience patterns in distributed systems
* Telecommunications sector experience — strong advantage
* Agile mindset with hands-on Scrum or Kanban experience
* Fluent English — written and verbal
* Interest in and practical exposure to AI-assisted development tooling
Nice to Have
* SOAP service integration and legacy modernisation experience
* Graylog or equivalent observability/logging platform
* German language skills (beneficial, not mandatory)
* Architecture certifications (TOGAF, AWS/Azure/GCP)
