📋 Description

• Contribute to design reviews for the 5G SA Core lab-to-production transition • Build and execute integration test plans against core network functions • Validate IoT and consumer provisioning flows end-to-end • Build automation — primarily in Python — for repeatable testing, configuration, and post-deployment validation • Reduce manual toil in the lab→prod handoff • Partner with vendor engineers, internal NetOps, security, and product teams to triage and resolve integration defects • Troubleshoot from the device through the RAN to the core • Document runbooks, test artifacts, and automation so the work is auditable

🎯 Requirements

• 7+ years of network engineering experience, with at least 2 years in 4G/5G mobile core (EPC and/or 5GC) • Working knowledge of 5G SA architecture and the major control- and user-plane NFs • Hands-on experience integrating or testing mobile core deployments • Production-grade Python: you write code others maintain, not just scripts • Familiarity with REST/gRPC, async I/O, and at least one test framework (pytest or equivalent) • Experience with IoT cellular networks (NB-IoT, LTE-M, or 5G IoT slices) • Solid troubleshooting fundamentals: packet captures, signaling analysis, log correlation across NFs
