About this role

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

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
