About the role

  • Design and deliver core networks that support essential features (voice, data, messaging), address customer use cases, and solve hard problems with novel, never-been-done solutions—while ensuring scale and reliability.
  • Partner across teams and vendors to stitch together solutions and bring them successfully to market.
  • Implement new features with zero disruption to live users through well-planned MOPs, maintenance windows, test plans, and phased rollouts.
  • Troubleshoot deeply—dig into network traces with partners and vendors to isolate root causes and resolve complex issues.
  • Interconnect networks—from private to commercial, roaming to MVNO—ensuring seamless interoperability.
  • Drive new standards in security and privacy, whether by encrypting data, eliminating unnecessary storage (e.g. CDRs), augmenting 3GPP/GSMA functions, or inventing new protections against malicious actors.
  • Stand up new network instances in new regions or with functionality tailored to evolving customer needs.

Requirements

  • 4+ years wireless Core network architecture experience, including IMS, EPC/PGW, MME, HSS, SGW (or 5G equivalents).
  • Hands-on operational skills—comfortable deploying, configuring, and debugging network functions in a startup environment.
  • Deep expertise in telecom features such as VoLTE/VoNR, VoWiFi, SMS/MMS over IP, and regulatory compliance (e911, NG911, CALEA).
  • Familiarity with 4G, 5G NSA, and 5G SA architectures.
  • Strong protocol knowledge: Diameter, SIP, GTP, and related cellular network protocols.
  • Vendor management experience, with the ability to hold external partners accountable.
  • Design documentation skills, from high-level architecture to detailed network diagrams.
  • Comfort with disruption—willingness to do things differently than legacy telecom approaches.
  • Preferred experience: Cloud-based network deployments; Launching MVNOs, roaming interconnects, IPX, trunking, and cross-network connections; RAN expertise and/or knowledge of SIMs, SIM applets, and OTA platforms.
  • Willingness to travel extensively, including international, especially during the first 6 months.
  • Willingness to relocate to NYC or DC (application asks if willing).
