Digital Architecture & Design

and documents the complete UC ecosystem following enterprise architecture principles.

UC Architecture & Strategy

• Define the end-to-end UC architecture covering CUCM, Unity Connection, CUBE, SIP infrastructure, UCCE, and Webex CC.

• Drive the UC roadmap aligned with business transformation and cloud migration strategies.

• Own the dial plan architecture, intercluster routing, numbering plan normalization, and cross regional governance.

• Lead design decisions for resiliency, HA, clustering, security, and SIP interoperability.

Design & Documentation Ownership

• Produce and maintain HLDs (High-level Designs) and LLDs (Low-level Designs) for UC & Contact Center environments.

• Document SIP call flows, integrations, trunking models, SBC logic, failover behavior, and overall service dependencies.

• Ensure alignment with existing design frameworks (SME/ILS, Webex CC routing logic, SBC universal call flow models).

• Maintain architecture landscapes including CUCM clusters, Unity clusters, voice gateways, SBCs, UCCE components, and Webex CC tenants.

Steering & Governance

• Act as architectural authority for all UC projects, changes, and new deployments.

• Review engineering designs and ensure consistency with standards and blueprint models.

• Collaborate with architects, network teams, security, and vendors to ensure integrated design governance.

• Evaluate new technologies, versions, and upgrade paths (e.g., CUCM, UCCE, Webex CC platform evolution).

SIP, CUBE & Interoperability Leadership

• Define SIP standards, normalization rules, routing logic, and QoS models.

• Architect CUBE deployments (centralized, distributed, or hybrid) and enforce SBC governance patterns.

• Specify security requirements, transport settings, encryption models, and interworking design guidelines.

Contact Center Architecture (UCCE, Webex CC)

• Architect integrations between CUCM, CUBE, UCCE, and Webex CC using standardized SIP SBC frameworks.

• Provide guidance for queueing strategy, routing logic, skill mappings, hours of operations, failovers, and cloud interconnectivity.

Technical Leadership

• Steer engineering teams by providing architectural guidance, design reviews, and implementation oversight.

• Act as the escalation point for complex design related issues.

• Ensure documentation, configuration standards, and architectural decisions are respected across regions., Because we are counting on innovative solutions, sustainable actions, connected thinking and on you, become a part of our formula for success and develop the future with us - in a global team that embraces diversity and equal opportunities irrespective of gender, age, origin, sexual orientation, disability or belief.
