Mobility Network Artchitect

Responsibilities

• Design, deploy, and support 4G/5G network connectivity solutions, including integration with carrier networks, mobile core elements, and enterprise/service provider infrastructure.
• Plan, implement, and maintain IPv4/IPv6 addressing strategies, including subnet allocation, IPAM processes, routing policy, NAT considerations, and large‑scale subscriber/device addressing.
• Troubleshoot and resolve issues across mobile packet core, transport, routing, DNS, DHCP, APN configurations, and service provider interconnects to ensure reliable service delivery.
• Collaborate with internal engineering, operations, vendors, and carrier partners to define network standards, operational procedures, and scalability requirements for mobile and service provider environments.
• Monitor network performance, capacity, and availability, and drive improvements related to resiliency, automation, security, observability, and operational efficiency.

• Bachelor’s degree in Electrical Engineering, Computer Science, Telecommunications, or related field, or equivalent practical experience.
• Strong hands‑on experience with 4G/LTE and 5G networking, including mobile architecture, subscriber connectivity, and carrier/service provider operations.
• Experience with SIM/eSIM provisioning platforms and workflows, including large‑scale activation, profile management, entitlement flows, and operational support.
• Deep knowledge of service provider IP networking, including BGP, OSPF/IS‑IS, MPLS, VRFs, QoS, CGNAT/NAT, DNS, DHCP, and routing policy.
• Proven experience managing IPv4 and IPv6 addressing in production environments, including IP planning, assignment strategy, subnetting, dual‑stack deployment, and IP address lifecycle management.
• Strong troubleshooting skills across Layer 2/Layer 3 networking, mobile services, carrier interconnects, and production operations, with the ability to work effectively in cross‑functional environments.

• Experience with mobile core and packet core technologies such as EPC, 5GC, APN/DNN design, policy control, roaming, and subscriber data flows.
• Experience building or supporting automation for network provisioning and operations using Python, APIs, Ansible, or similar tooling.
• Knowledge of service assurance and observability tools, including telemetry, SNMP, syslog, packet analysis, and performance monitoring in carrier‑grade environments.
• Experience working with carrier/vendor management, service turn‑up, certification processes, and production change management in service provider networks.
• Relevant certifications such as CCNP/CCIE, JNCIP/JNCIE, or telecom/mobile networking certifications are a plus.
