QC Collaborator

Call Functional Testing

• Test main call flows on iOS and Android: 1-1 and group voice/video calls (outgoing and incoming) and in-call controls;
• Test call behavior in different situations: app in background or killed, missed or declined calls, and interruptions from other calls;
• Check call history, notifications, and permissions.

Audio Devices & Integrations

• Test calls with external audio devices (speaker, wired and Bluetooth headsets), including switching devices during a call;
• Test calls on CarPlay and Android Auto.

Network Conditions

• Run basic call checks under different networks (Wi-Fi, 4G/5G, network switching, weak connections), focusing on call drops and reconnection;

QC Process

• Write and maintain test cases, run regression and release testing, and report test results in Jira;
• Reproduce issues, collect device logs, and log clear bugs in Mantis with steps and evidence;
• Work with developers and the QC lead to verify fixes and support release sign-off.

• Solid QC fundamentals: test design techniques, bug lifecycle, writing test cases and bug reports;
• Hands-on mobile testing experience on iOS and Android: device/OS fragmentation, app lifecycle, permissions, push notifications, basic debug logs;

Nice to have

• Previous experience testing Call/VoIP products (SIP/WebRTC concepts, CallKit/ConnectionService, codecs, call KPIs);
• Network knowledge: TCP/UDP, NAT/firewall, latency/jitter/packet loss;
• Familiar with Charles/Proxyman, Wireshark, or Network Link Conditioner.
