Design and maintain IREG-based test campaigns for roaming partners, network changes and service launches across Data, Voice and SMS. Manage the test SIM and eSIM fleet, remote test probes, campaign configuration, scheduling, execution, reporting and coverage history. Build repeatable test pipelines, integrate smoke and regression suites into CI/CD, and provide clear release gates; so that core network changes and Steering of Roaming adjustments never quietly break the existing footprint. Define the KPIs, baselines and thresholds that tell us the service is healthy. Correlate synthetic test results with production KPIs and real customer journeys, and turn what you find into alerts and runbooks the Operations team can act on. Design and run the tests that show our geo-redundancy behaves as designed, i.e. site failover and failback, Diameter and GTP path recovery, session survival, data consistency after a switch; and verify that our core platforms deliver the capacity they were dimensioned for, under sustained load and under signalling bursts. Analyse PCAP, MAP/SS7, Diameter, GTP and DNS traces alongside monitoring data to isolate failures, support root cause analysis, validate fixes and strengthen regression coverage.

You've worked in telecom QA, network testing, service assurance or roaming validation. You know how LTE/EPC fits together. Give you a registration or session flow and you'll find where it broke. Wireshark is where you go first, not last. You write your own automation in Python or something close, and you keep regression suites running in CI/CD.

Experience at a roaming hub, IPX provider, mobile operator or MVNO, including partner interoperability testing. Hands-on SIM box or remote testing probe management. Exposure to 5G roaming and VoLTE roaming, including S8HR and SMS over IP. Familiarity with HSS/HLR, PCRF and OCS functions, and how they show up in roaming failures. Working knowledge of GSMA roaming procedures and documents, including IR.21, IR.24, IR.35, IR.38 and IR.92.
