Job Description
We are looking for someone who understands the heart of mobile networks — how subscribers move, connect, and roam across the world. In this role, you will manage the critical mobility functions that keep our customers connected everywhere. From Update Location procedures in HLR, HSS, and UDM, to designing and maintaining roaming profiles across 3G, 4G, and 5G, you’ll make sure mobility always works seamlessly.
You’ll work on roaming profiles that not only define network access but also identify VPLMNs by both GTs and MCC/MNC. You’ll handle the nuances of Cancel Location when new IMSIs register on the same SIM, and you’ll ensure that subscriber state is synchronized across multiple data centers — even when traffic scales to tens of millions of users.
Resilience is key in this role. You’ll support VNF recovery and failover without service impact, and you’ll troubleshoot complex roaming issues across multi-vendor environments. Along the way, you’ll work with interconnect agreements,...
