Backed by premier Silicon Valley investors, the team is rethinking telecom from the ground up—designing infrastructure that gives individuals and mission-critical operators greater control over their data. This is not incremental telecom. Its a clean-sheet approach to secure, cloud-native wireless infrastructure that supports U.S. and allied national security priorities. The Opportunity Were hiring a Wireless Network Architect to design, build, and operate a modern, cloud-based 4G/5G Core network. This role is for someone who understands legacy telecom deeply—but is motivated to reinvent it. You'll operate at the intersection of architecture and execution: shaping system design, deploying production infrastructure, working directly with vendors, and ensuring reliability at scale. Your work will directly impact national security and privacy-forward communications. What You'll Do Architect and deploy 4G/5G Core networks (voice, data, messaging) with scale and reliability. Lead implementation of IMS, EPC, and 5G Core functions (HSS/UDM/UDR, MME/AMF, SGW/UPF, etc.). Design and execute seamless feature rollouts (VoLTE, VoNR, VoWiFi, SMS/MMS over IP) with zero user disruption. Interconnect across roaming partners, MVNOs, private networks, IPX, and trunking environments. Troubleshoot complex network issues using traces and protocol-level analysis. Drive enhanced privacy and security standards beyond traditional telecom norms. Launch new network instances across regions and evolving mission requirements. What You Bring 4+ years of wireless Core network architecture experience (4G

LTE, 5G NSA/SA

). Deep knowledge of

IMS, EPC, 5G

Core, and related protocols (Diameter, SIP, GTP). Experience deploying, configuring, and debugging network functions hands-on. Strong understanding of telecom regulatory requirements (e911, NG911, CALEA). Vendor management experience and strong technical documentation skills. Comfort operating in a fast-moving startup environments Cloud-native Core deployments MVNO launches, roaming interconnects, IPX RAN familiarity and SIM/SIM applet/OTA expertise Fluency in Mandarin (Preferred) US Citizenship (Required)
