• Build enterprise telephony capabilities including call recording, voicemail, conferencing, whisper/barge, monitoring, queue management and compliance recording.
• Define extensible Voice APIs, SDKs, webhooks and event frameworks that enable seamless integrations with third-party applications and ecosystem partners.
• Lead customer migration initiatives, including provider migrations, number portability, hosted phone onboarding, and enterprise telephony transitions, while minimizing customer disruption.
• Partner with Engineering, Infrastructure, Security, Compliance, Support and Go-to-Market teams to deliver highly reliable, globally scalable voice products.
• Establish and monitor platform KPIs including call completion rates, SIP reliability, provisioning success, IVR containment, routing efficiency, call quality (MOS), queue abandonment, agent utilization, billing accuracy, platform availability and customer satisfaction (CSAT).
• Develop and execute the long-term roadmap for enterprise telephony, AI-powered communications, multi-vendor architecture and next-generation voice experiences, ensuring HighLevel maintains competitive parity and platform leadership.

Requirement:

• 8+ years of Product Management experience, including ownership of communications, telecommunications, voice infrastructure, CPaaS, CCaaS or enterprise platform products.
