Wireless Network Architect; 4G​/5G Core - NY

Wireless Network Architect (4G/5G Core)

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

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.

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 r work will directly impact national security and privacy‑forward communications.

• 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, Vo Wi Fi , 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.

• 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)
