Standards and Compliance: Establish and enforce engineering design standards, approved product and configuration baselines, Quality of Service (QoS) requirements, cybersecurity controls, and disaster recovery and business continuity requirements.

Performance Reporting: Establish and communicate meaningful measures for engineering backlog, milestone delivery, design quality, lifecycle risk, operational readiness, and recurring technical issues.

3. Technical Leadership and Architecture

Solution Architecture: Serve as the Subject Matter Expert and architectural authority for assigned enterprise voice, VTC, SIP trunking, Session Border Controller (SBC), telephony, and collaboration solutions.

Technical Roadmaps: Develop and maintain technical roadmaps for modernizing legacy PBX and telephony environments and transitioning to appropriate on-premises, hybrid, UCaaS, and cloud collaboration platforms.

Enterprise Telephony Engineering: Provide technical direction for enterprise dial plans, E.164 number normalization, digit manipulation, call routing, SIP trunking, carrier interconnections, PSTN services, voice gateways, voicemail, and emergency calling capabilities.

Availability and Resiliency: Define technical requirements for high availability, geographic redundancy, survivability, disaster recovery, capacity management, and service continuity.

Technology Evaluation: Lead product evaluations, proof-of-concept activities, interoperability testing, and technical risk assessments for new voice, video, and collaboration technologies.

Cross-Functional Alignment: Coordinate closely with Transport Engineering, Network Operations, Cybersecurity, program leadership, customers, and vendor partners to align collaboration solutions with enterprise infrastructure, security, and operational requirements.

Vendor and Carrier Coordination: Lead technical engagements and escalations involving equipment manufacturers, software providers, telecommunications carriers, SIP service providers, and system integrators.

4. Hands-On Technical Engineering and Escalation

Design and Deployment: Perform and oversee the configuration, integration, testing, and deployment of IP telephony systems, SIP proxies, SBCs—including AudioCodes, Ribbon, and Cisco CUBE—and unified communications platforms.
