Perform interoperability testing when onboarding new telecom solutions, hardware, or carrier integrations to ensure compatibility with the existing platform.
Serve as the senior escalation point for complex voice quality and call-routing issues, analyzing SIP/RTP packet captures with tools like Wireshark, Homer, and vendor-specific diagnostics.
Lead post-incident reviews and drive root-cause analysis to prevent recurrence.
Collaborate with customer support teams to resolve voice-related customer escalations, providing deep technical analysis and timely resolution.
Participate in a team on-call rotation providing 24/7 support for critical production voice services.
Build and maintain automation (Python, Bash, or Go) for provisioning, monitoring, configuration management, and routine maintenance tasks.
Contribute to internal tooling and APIs that enable self-service for carrier management, number porting, and call-routing configuration.
