The Voice Quality squad plays a critical role in ensuring customers can rely on Aircall for business-critical communication. Your investigations and improvements directly impact call reliability and customer trust.

This role focuses heavily on voice quality, VoIP troubleshooting, and telecom integrations, and requires collaboration across internal engineering teams and external carrier partners.

You will work closely with customers, support teams, and telecom providers to diagnose issues such as poor audio quality, call failures, reachability problems, and carrier-related routing issues.

This role primarily supports regional business hours, while collaborating with Aircall’s global support organization when additional coverage or expertise is required.

This role will require you to be minimum 1 day a week in-office.

Improve escalation processes to ensure high-quality case handoffs
Create and maintain internal troubleshooting documentation

Key Responsibilities: Continuous Improvement

Monitor support trends and identify recurring voice-quality issues
Recommend improvements to product features, support processes, and customer troubleshooting workflows

Required Qualifications:

Experience supporting VoIP, telecom, or UCaaS platforms in a technical support or operations role
Strong understanding of VoIP and telephony concepts, including SIP signaling and call routing
Solid understanding of IP networking fundamentals (TCP/IP, NAT, VLANs, QoS, LAN/WAN)
Experience troubleshooting real-time communications issues such as poor audio quality, dropped calls, or call routing failures
Strong written and verbal communication skills in English
Ability to clearly explain complex technical issues to both technical and non-technical audiences
Strong organizational skills and the ability to manage multiple issues simultaneously in a fast-paced environment
Customer-focused mindset and strong problem-solving skills

Preferred Qualifications:

Experience troubleshooting WebRTC-based communication platforms
Experience working with telecom carriers or telephony providers
Familiarity with packet capture analysis (PCAP) or SIP trace analysis
Experience with monitoring and observability tools such as Datadog
Familiarity with analytics tools such as Looker
