## Join our Team
About this opportunity
We are seeking an experienced and technically proficient Solution Architect to lead the end-to-end solution design and upgrade strategy for UDM (User Data Management), IMS (IP Multimedia Subsystem), and Packet Core network elements. The architect will collaborate with cross-functional teams to define upgrade paths, validate design impacts, and ensure seamless execution in live network environments.
What you will do
Upgrade Strategy & Planning
- o Define upgrade approach (ISSU vs. redeployment) based on product capabilities and customer environment.
- o Evaluate backward compatibility and interoperability impacts across EPC/5GC/Cloud components.
- o Align upgrade activities with network architecture roadmap, lifecycle policies, and vendor release cycles.
- Solution Architecture & Design:
- o Develop high- and low-level solution architecture for upgrades, including software/hardware pre-requisites.
- o Create detailed upgrade impact assessments and rollback strategies.
- o Validate upgrade path for clustered/HA deployments, geo-redundancy, and distributed architectures.
- Stakeholder Coordination:
- o Work with delivery, operations, product teams, and customers to gather requirements and constraints.
- o Participate in technical governance and change control boards for upgrade approvals.
- o Present solution documents, risk mitigations, and test validation plans to internal and external stakeholders.
- Tools, Automation & Compliance:
- o Leverage automation for pre-checks, health-checks, and post-upgrade validation (e.g., EVFNM, CaaS scripts).
- o Ensure compliance with security, data protection, and audit standards during upgrade cycles.
- o Integrate solutions with CI/CD pipelines where applicable.
- Documentation & Knowledge Sharing:
- o Develop and maintain architecture documentation, upgrade playbooks, and decision logs.
- o Share knowledge across teams via technical sessions, mentoring, and documentation
