The Prospect

A Cellular Architect for this engagement must combine telecom architecture (LTE/5G IoT), cybersecurity threat modeling, and utility-scale AMI communication expertise, with solid capabilities in risk assessment, encryption/identity, and long-term network strategy.

A comprehensive analysis of potential impacts to Client cellular functions such as availability, integrity of commands and data, remote operations and service disconnect, fleet management and provisioning, and over-the-air (OTA) updates and firmware distribution. A comprehensive assessment of the public LTE carrier core compromise scenario should begin with a transparent definition of the threat scenarioincluding underlying assumptions, relevant threat actors, preconditions, and potential exposure pathways between carrier infrastructure

Your Key Responsibilities

The Cellular IoT Architect shall assess and evaluate clients proposed communications approaches for upgradation, with a focus on resilience, and long-term viability. Provide an assessment of the client ecosystem and the timelines associated with the modules and services provided by the major wireless carriers.
