Transport & Backhaul Engineering 

• Define transport and backhaul requirements for PLTE/5G deployments, ensuring alignment between core network services, radio access networks, and utility communications objectives. 
• Collaborate with transport, routing, cybersecurity, and infrastructure teams to develop architectures that support PLTE/5G network performance, resiliency, scalability, synchronization, and operational requirements. 
• Evaluate transport network designs for latency, QoS, redundancy, traffic engineering, timing, and service availability impacts on critical LTE and 5G core functions. 

RAN, RF, & Wireless Integration 

• Support integration of eNodeB and gNodeB infrastructure with private LTE and private 5G core networks. 
• Collaborate with RF engineering teams on coverage, capacity, mobility, performance, and service quality objectives. 
• Evaluate emerging RAN, Open RAN, and private wireless technologies for utility use cases. 

PLTE/5G Cybersecurity & Critical Infrastructure Security 

• Develop cybersecurity architectures for Private LTE and Private 5G networks used in critical infrastructure and utility OT environments. 
• Evaluate and influence security architecture strategies for private LTE and 5G networks, ensuring appropriate integration of security controls across core, transport, cloud, and operational technology environments 
• Align PLTE designs with utility cybersecurity expectations, defense-in-depth principles, Zero Trust concepts, and applicable NERC CIP considerations when the environment supports Bulk Electric System or other regulated operational functions. 

Operational Readiness & Performance Management 

• Provide architectural guidance for monitoring, alarming, KPI, and reporting frameworks supporting PLTE core, RAN, transport, security, and operational systems. 
• Advise on lifecycle management strategies, technology roadmaps, capacity planning approaches, software maintenance considerations, and platform evolution initiatives. 
• Evaluate service-impacting events and performance trends to identify architectural improvements that enhance reliability, resiliency, and operational effectiveness. 

Preferred Qualifications
