## Join our Team
About this opportunity
As a UDM / Core Data & Provisioning Solution Architect, you will shape end-to-end solutions across Ericsson’s subscriber data and provisioning portfolio, including CCDM, CCRC, CCSM, HSS/HLR, EDA, and related 4G and 5G Core network functions. You will translate customer business and technical needs into secure, scalable, and resilient architectures for cloud-native and hybrid environments.
Working with customers, product and project teams, delivery engineers, operations, and partners, you will lead solution definition from requirements and high-level design through deployment assurance and operational handover, ensuring solutions meet performance, availability, interoperability, security, and lifecycle requirements.
What you will do
- Lead customer and stakeholder workshops to understand business objectives, requirements, constraints, and migration needs.
- Define end-to-end architectures for CCDM, CCRC, CCSM, HSS/HLR, EDA, and their integration with 4G/5G Core network functions and OSS/BSS systems.
- Produce and review architecture deliverables, including high-level designs, interface and deployment views, design decisions, and risks.
- Shape cloud-native deployment approaches covering Kubernetes/CNF topology, resilience, scaling, observability, and lifecycle management.
- Define integration principles and end-to-end flows across interfaces and protocols such as Diameter, HTTP/2, REST, SOAP, XML, LDAP, and 5G SBI/N interfaces.
- Assess capacity, performance, availability, disaster recovery, networking, and security requirements, identifying dependencies and trade-offs.
- Develop migration and upgrade strategies covering coexistence, data transition, rollback, and service continuity.
- Guide technical teams through detailed design, integration, verification, and acceptance, ensuring traceability to customer requirements.
- Lead technical governance, design reviews, risk management, and resolution of cross-domain architecture issues.
- Support bids with solution descriptions, estimates, compliance responses, and scope clarification.
- Ensure designs are implementable and supportable, contributing to documentation, knowledge transfer, and handover.
- Drive standardization and automation in solution delivery.
