Job Summary:

We are seeking a Senior Solution Integrator with proven experience in executing complex UDM (User Data Management) upgrades involving core components such as CCRC, CCSM, CCES, and CCDM. The role requires deep understanding of Ericsson Cloud Infrastructure, integration lifecycle, cluster-based deployments, and the ability to handle customer-facing upgrades with zero/minimal downtime.  

Key Responsibilities:

Upgrade Execution

• Perform end-to-end upgrade of UDM components: CCRC, CCSM, CCES, and CCDM, including validation, configuration migration, and service cutover.
• Drive the upgrade via redeployment or ISSU approach based on product compatibility and customer environment.
• Coordinate version compatibility checks, rollback planning, and delta validation before and after upgrade.

Solution Integration & Validation

• Integrate UDM components with surrounding nodes: HLR, HSS, UDR, UDSF, AUSF, PCRF.
• Validate interworking with Diameter, LDAP, and HTTP/REST interfaces.
• Execute functional and performance test cases post-upgrade using Ericsson validation tools (e.g., EVFNM, CCD CLI, REST APIs).

Automation & Tools

• Utilize automation scripts (e.g., Ansible, Bash) for health checks, node readiness, and service restarts.
• Handle containerized deployments in Ericsson CaaS / CCD-based environments using Helm/K8s tools.
• Work with backup/restore tools for cluster and DB safety before upgrade initiation.

Technical Troubleshooting & Optimization

• Proactively identify and troubleshoot upgrade-related issues across nodes, clusters, or interfaces.
• Provide logs and RCA documentation for post-upgrade issues (connectivity, schema migration, data sync).
• Fine-tune system parameters and cluster configurations for optimized post-upgrade performance.

Documentation & Governance

• Prepare and review MOPs (Method of Procedure), CRs (Change Requests), and deployment plans.
• Maintain technical documentation, design changes, and interface control documents.
• Support compliance with security and audit controls during the upgrade.

Stakeholder Collaboration

• Coordinate with delivery teams, customer operations, and global product support for successful upgrade execution.
• Provide regular progress updates to internal and external stakeholders.
• Participate in governance calls, issue triage, and handover sessions.
