MQA Engineer (UniFi Switching)
Ubiquiti, Taiwan +1
What you will do
Protocol & Feature Validation
- Manually validate core L2/L3 switching features: VLANs, STP/RSTP, LACP/port-channels, LLDP, IGMP/MLD snooping, QoS, ACLs, static/dynamic routing
- Validate PoE behavior (PoE/PoE+/PoE++) across port classes, power budgets, and mixed-load scenarios
- Test switch management interfaces — CLI, SSH, SNMP, REST API, and UniFi Network application/controller integration
- Perform interoperability testing across multi-vendor topologies and mixed firmware versions
- Validate clustering, redundancy, and failover behavior under various failure conditions
Firmware & System Testing
- Perform long-duration soak/stability testing to catch memory leaks, port flaps, and firmware degradation over time
- Test system behavior under scale conditions (high MAC/ARP table size, VLAN scale, heavy traffic load)
- Validate authentication, authorization, and access control (802.1X, RADIUS, management access)
Debugging & Root Cause Analysis
- Debug using switch logs, CLI diagnostics, packet captures, and port/interface statistics
