Device & Mesh Testing

• Perform interoperability qualification and validation testing between Telstra WiFi Boosters and Telstra Smart Modems
• Execute end-to-end mesh testing on Telstra Smart Modems, ensuring compliance with expected behaviour and industry standards.
• Conduct sanity, regression, and stability testing on firmware upgrades and downgrades for boosters and gateways.
• Perform manual WiFi performance testing, including coverage, throughput, roaming behaviour, failover, reconnection, and overall mesh effectiveness.
• Execute booster onboarding and connectivity testing using Ethernet and WPS, validating 2.4GHz / 5GHz behaviour, channel changes, and client connectivity.

Test Execution & Defect Management

• Capture logs, record results, and clearly document findings during test execution.
• Raise defects and observations through standard tracking and reporting processes using JIRA, ensuring all supporting logs, evidence, and reproduction steps are included.
• Support root cause analysis activities by providing clear test data and validating fixes.

Collaboration & Vendor Engagement

• Work closely with product leads, engineering teams, and vendors to plan, execute, and validate test activities.
• Generate clear and concise test reports and updates for wider stakeholder consumption.
