You’ll lead the design and growth of our Packet Core (EPC/5GC), ensuring our network scales effortlessly as our global traveler base doubles and triples.
You’ll be our primary architect for global connectivity, managing roaming coverage through IPX/GRX providers and securing bi-lateral agreements that keep our users online everywhere.
You’ll dive deep into signaling procedures across 3G, 4G, and 5G NSA. When a connection fails, you’re the expert who decodes the "why" using tools like Wireshark to look under the hood of Diameter and GTP signaling.
You’ll fine-tune critical network flows—from the moment a user "attaches" to the network to the creation of high-quality voice and data bearers—ensuring every byte is delivered with precision.
You’ll lead design reviews and manage the "Acceptance Testing" (ATP) phase to ensure our partners deliver to the high standards our users expect.
Requirements
You’ve spent significant time in the "engine room" of a Tier 1 Carrier, Mobile Operator, or a major Equipment Provider. You understand the stakes of a live, global network.
You are fluent in the language of mobile networks. Whether it's legacy 3G (SGSN/GGSN), dominant 4G (MME/PGW), or the transition to 5G, you understand how these systems interlock.
You have a rock-solid grasp of IP networking—BGP routing, subnets, and ASN management are second nature to you.
You understand that "it’s always DNS." You have hands-on experience architecting the DNS hierarchy (S-NAPTR) that allows mobile nodes to discover one another across the globe.
