Principal Cloud & Telephony Architect

Sunstate Equipment Co., LLC•Phoenix, AZ

About The Position

The Principal Cloud and Telephony Architect is a senior technical leader responsible for enterprise architecture, design, and operational excellence across cloud infrastructure (IaaS) and SaaS-based enterprise telephony (Dialpad). This role defines and governs cloud platform standards, resilience and disaster recovery strategy, service management practices, and operational/network support models—while ensuring consistent, secure, highly available communications across multi-site locations throughout the US. This role partners closely with Development, Operations & Network, Security and key business stakeholders to deliver scalable platforms, reliable services, and measurable outcomes (availability, performance, cost efficiency, and supportability).

Requirements

10+ years in infrastructure/platform engineering, with significant experience in enterprise cloud architecture (IaaS) and operational leadership.
Deep expertise in cloud networking concepts (VPC/VNet, routing, DNS, load balancing, firewalls, private connectivity).
Strong background in resilience/DR design, including RTO/RPO planning, dependency mapping, and DR testing.
Demonstrated capability to lead cross-functional programs and influence architecture decisions across multiple teams.
Experience architecting and supporting enterprise telephony in a SaaS model (Dialpad strongly preferred).
Understanding of voice fundamentals and troubleshooting: SIP concepts, call flows, QoS, and voice-quality drivers (latency/jitter/packet loss/MOS).
Experience operating multi-site telephony deployments across geographically distributed locations in the US.
Familiarity with device and endpoint standards (softphone/deskphone/headsets), onboarding/offboarding workflows, and admin governance.

Responsibilities

Own enterprise cloud reference architectures and patterns for compute, storage, networking, identity, and security across one or more cloud providers (e.g., Azure/AWS/GCP).
Lead platform decisions for landing zones, account/subscription strategy, network segmentation, routing, DNS, and connectivity (VPN/ExpressRoute/Direct Connect).
Define and enforce standards for IaC (Infrastructure as Code), configuration management, environment consistency, and platform governance.
Design and guide implementation of cloud operational models: patching, capacity management, performance monitoring, incident response, and lifecycle management.
Work with the teams to ensure that the DR strategy and resiliency tiers (RTO/RPO targets) are established for critical services.
Establish DR testing programs (tabletop + functional failover), runbooks, and continuous improvement cycles based on lessons learned.
Partner with Network and Security teams to design reliable hybrid connectivity and site readiness standards for multi-site operations.
Define and oversee operational controls for routing, QoS, firewall rules, segmentation, and secure remote administration.
Ensure observability and troubleshooting coverage across cloud infrastructure, WAN/ISP circuits, and unified communications traffic paths.
Serve as the technical owner for the enterprise Dialpad telephony environment, including architecture, provisioning strategy, and ongoing operations.
Define governance for number management, call routing policies, auto attendants, call queues, ring groups, integrations, and role-based administration.
Design multi-site deployment standards: site dialing plans, emergency calling considerations, device standards (desk phones, softphones, headsets), and user lifecycle workflows.
Establish reliability and support practices for voice quality and performance (latency, jitter, packet loss), including cross-team troubleshooting with Network/ISP partners.
Lead vendor management and escalation with Dialpad and related carriers/providers; review releases and coordinate change adoption.
