You will lead the solution design across key operational domains, including Network Inventory (Physical and Logical - PNI/LNI), Workflow Systems, Monitoring, Event Management, and IT Integration. Your expertise will be crucial in strategically replacing existing OSS legacy systems including TIBCO-based IT integration (covering Enterprise Integration services incl. business process logic and Service order management) with a modern, API-driven, and cloud-native OSS architecture, significantly enhancing business agility, accelerating time-to-market, and optimizing operational efficiency.
Key Responsibilities:
- Design and execute strategic roadmaps for our OSS Transformation, specifically covering PNI/LNI, Workflow Systems, Monitoring, Event Management, and the replacement of legacy IT Integration.
- Lead the design and implementation of a new IT integration layer fully compliant with TM Forum Open APIs and Open Digital Architecture (ODA) principles across our IT ecosystem.
- Define and implement integration and orchestration patterns (API Gateway, service mesh, event streaming ...) to ensure scalability, resilience, and decoupled system communication across OSS domains.
- Design and develop modern cloud-native solutions for all core OSS domains, utilizing microservices, containerization, and event-driven architectures as the foundation for this new IT Integration.
- Mentor technical teams and establish best practices to build organizational capability in advanced OSS architecture and the new IT integration solution.
- Collaborate closely with DevSecOps teams to design and maintain robust CI/CD pipelines, automated testing, and deployment strategies supporting continuous delivery of integration components.

- Proven hands-on experience with TM Forum Open APIs and Open Digital Architecture (ODA) implementation, with a focus on building new integration solutions including practical application of integration patterns (synchronous/asynchronous, event-driven, message bus, API Gateway, choreography vs. orchestration) and modern microservices-based integration. Candidate must understand architecture standards, design patterns, shape short-term and long-term architecture solution options involving pros and cons.
- Practical understanding of DevSecOps principles, CI/CD tools and pipelines.
- Proficiency in modern backend technologies (Java, Python) and software design best practices.
- Proven/prior experience in developing OSS applications leveraging microservices architecture and cloud-native technologies and solutions including hybrid integration architecture.
- Experience with TIBCO products (BW5, BW6, BWCE, FOM/FOS) and TIBCO transformation to a new architecture is an advantage.
- Proficiency in modern architectural principles (microservices, containerization, cloud platforms, event-driven architectures) for building next-gen IT integration.
