Wireless Network Architect (4G/5G Core)

Privacy-First Cellular Infrastructure | Mission-Driven | Growth-Stage Startup

About the Company

Founded by leaders from top defense-tech and national security organizations, this venture-backed company is building a next-generation, privacy-first cellular network. 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)
