Software Integration Lead – 5G CORE

Own the integration architecture and delivery for back-end systems that interface directly with the 5G Core: SIM/eSIM provisioning, CRM, billing and online/offline charging, and device management.

Define and implement the integration between SIM and eSIM provisioning infrastructure and core subscriber management — including subscriber profile delivery, remote SIM provisioning workflows, and profile lifecycle management across satellite and ground.

Design and own the interface between CRM and the core network: subscriber record synchronisation, service entitlement and quota management, and real-time event delivery for customer-facing workflows.

Lead integration of the billing and charging stack with the core charging interfaces — CDR generation and delivery, online charging authorization flows, and reconciliation between core charging events and BSS billing records.

Integrate device management capabilities with core network functions, including device policy enforcement, configuration delivery, and status signalling across the satellite link.

Define interface contracts (API specifications, data models, event schemas) at each BSS/OSS-to-core boundary; maintain them as the engineering source of truth shared across core software and back-end platform teams.

Build and maintain integration test harnesses for each BSS/OSS-to-core interface; drive automation and define acceptance criteria for every interface at each release milestone.

Own defect triage and root-cause analysis for integration failures at BSS/OSS-to-core boundaries; coordinate resolution across core software and back-end platform engineering teams.

Lead and mentor a small integration engineering team (2–4 engineers); set delivery cadence and engineering quality standards.
