Overview:
Key responsibilities
- Act as the highest level of technical escalation (L3) for incidents raised against the Nokia FlowOne platform and its integrations.
- Perform root cause analysis on complex production issues — provisioning failures, orchestration errors, and service activation defects across FlowOne modules.
- Troubleshoot cross-system integration issues between FlowOne and upstream/downstream network elements: HSS/HLR, PCRF, OCS/billing platforms (Matrixx, Aria), and SIM/IMSI provisioning systems.
- Diagnose resource allocation failures between FlowOne and Nokia Unified Inventory (UIV) — e.g. incorrect or unavailable port, bandwidth, or equipment records blocking service activation.
- Analyze Diameter protocol traces (S6a, Gx, Gy/Ro, Cx/Sh) to isolate provisioning sync issues, unknown-subscriber errors, and related result-code failures.
- Own and drive resolution of P1/P2 incidents impacting customer-facing services such as IMSI provisioning, activation, and data/voice service delivery.




- Coordinate with Nokia vendor support and engineering teams on platform-level bugs, patches, and escalations.
- Review orchestration workflows, catalog configurations, and activation rules within FlowOne to identify systemic defects.
- Build and maintain runbooks, a known-error database (KEDB), and troubleshooting guides for L1/L2 teams.
- Monitor system health via Grafana/Elasticsearch dashboards to proactively identify error spikes and provisioning failures before they escalate.
- Participate in a rotational on-call schedule to support 24x7 production operations.
- Support problem management — identify recurring issues and drive permanent fixes with engineering and vendor teams.
- Review and validate changes and patches prior to production deployment as part of the change management process.
