Senior VoIP Pbx Engineer

In this role, we want you to lead the engineering and operational work that keeps our VoIP PBX environment stable, secure, and scalable.

• Design, deploy, and maintain VoIP PBX solutions (e.g., SIP-based systems), including core call flows, routing, and dial plans.
• Configure and manage SIP trunks, inbound/outbound calling, number normalization, and carrier interop.
• Implement and tune voicemail, IVR, conferencing, hunt groups, call queues, and call recording workflows (where applicable).
• Ensure reliability by building and refining monitoring, alerting, and log/trace practices for call quality and uptime.
• Troubleshoot production issues end-to-end (SIP signaling, RTP/media flow, codecs, NAT/firewalls, latency, and configuration drift).
• Collaborate with networking, security, and application stakeholders to integrate PBX services with external systems.
• Harden systems through secure configuration baselines, access controls, and vulnerability awareness.
• Document architectures, runbooks, and standard operating procedures to improve team velocity and reduce outages.
• Mentor team members and contribute to technical design reviews and best-practice improvements.
