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.

Key Responsibilities:

- Upgrade Strategy & Planning:
- Define upgrade approach (ISSU vs. redeployment) based on product capabilities and customer environment.
- Evaluate backward compatibility and interoperability impacts across EPC/5GC/Cloud components.
- Align upgrade activities with network architecture roadmap, lifecycle policies, and vendor release cycles.

- Solution Architecture & Design:

- Develop high- and low-level solution architecture for upgrades, including software/hardware pre-requisites.
- Create detailed upgrade impact assessments and rollback strategies.
- Validate upgrade path for clustered/HA deployments, geo-redundancy, and distributed architectures.

- Stakeholder Coordination:

- Work with delivery, operations, product teams, and customers to gather requirements and constraints.
- Participate in technical governance and change control boards for upgrade approvals.
- Present solution documents, risk mitigations, and test validation plans to internal and external stakeholders.

- Tools, Automation & Compliance:





- Leverage automation for pre-checks, health-checks, and post-upgrade validation (e.g., EVFNM, CaaS scripts).
- Ensure compliance with security, data protection, and audit standards during upgrade cycles.
- Integrate solutions with CI/CD pipelines where applicable.

- Documentation & Knowledge Sharing:

- Develop and maintain architecture documentation, upgrade playbooks, and decision logs.
- Share knowledge across teams via technical sessions, mentoring, and documentation.

Required Skills & Experience:

- Telecom Domain Expertise:
- Deep understanding of UDM (HSS, UDR, UDSF, AUSF), IMS (CSCF, TAS, MGCF), and Packet Core (MME, SGW, PGW, AMF, SMF, UPF) in EPC/5GC networks.
- Proven experience in at least 2-3 large-scale upgrade projects involving these domains.

- Technical Skills:

- Familiarity with virtualization (VMware, OpenStack) and containerization platforms (Kubernetes, Docker, CaaS).
- Competence in scripting (Python, Bash, Ansible) for automation.
- Experience with integration and deployment tools like Git, Jenkins, Helm is a plus.

- Design & Analysis:

- Robust grasp of system interdependencies, signaling flows (Diameter, SIP, HTTP2, GTP), and failover mechanisms.
- Ability to conduct impact analysis across interfaces (Nxx, Sxx, Gx, Rx, etc.).

- Soft Skills:

- Excellent communication and stakeholder management.
- Analytical mindset and problem-solving orientation.
