The Senior Network Engineer is responsible for the advanced design, implementation, optimization, and operational support of Berkshire Hathaway Energy’s enterprise network infrastructure. This role applies deep technical expertise to deliver reliable, scalable, and secure network solutions across WAN, LAN, wireless, data center, and network access environments.

• Design, implement, and optimize complex network solutions supporting high availability, performance, and security across enterprise WAN, LAN, wireless, data center, and network access environments.
• Execute detailed engineering designs and implementation plans aligned with established network architectures, standards, and roadmaps.
• Lead complex deployments, upgrades, and technology refreshes, including large‑scale or high‑risk changes requiring advanced technical expertise.
• Serve as a senior technical resource for routing, switching, segmentation, and network access technologies, providing guidance and technical review for engineering activities.
• Implement and enhance network automation solutions using Python, YAML, Ansible, and related tools to improve deployment consistency, reduce manual effort, and increase operational efficiency.
• Participate in proof‑of‑concepts and evaluations of new technologies in collaboration with network architects and technical leadership.
• Provide senior‑level escalation support for complex or high‑impact network incidents, leading troubleshooting efforts, root cause analysis, and remediation activities.
• Monitor network performance and reliability metrics, identifying trends, risks, and opportunities for improvement.
• Collaborate with security, systems, OT, cloud, and application teams to implement secure, compliant, and well‑integrated network connectivity solutions.
• Develop and maintain detailed network documentation, implementation guides, and operational procedures.
• Mentor and provide technical guidance to Network Engineer 1, 2, and 3 staff, supporting skill development and consistent engineering practices.
• Coordinate with vendors and service providers on advanced troubleshooting, escalations, and planned engineering activities.
• Participate in on‑call rotations and lead complex after‑hours maintenance and change activities as required.
• Perform additional senior‑level engineering responsibilities as assigned.

• Bachelor's degree in information systems, computer science or related technical field or equivalent work experience. (Typically four years of additional related, progressive work experience would be needed for candidates applying for this position who do not possess a bachelor's degree)
• Five or more years additional directly related technical experience is required.
• Cisco Certified Network Professional (CCNP) certification or demonstrated equivalent work experience supporting advanced enterprise routing, switching, wireless, and network access technologies.
• Extensive progressive experience supporting and engineering enterprise network environments.
• Advanced experience designing and implementing enterprise WAN routing solutions, including BGP, OSPF, EIGRP, static routing, and associated redundancy and resiliency mechanisms.
• Advanced knowledge of enterprise LAN switching, including VLAN and trunking design, Spanning Tree (RSTP/MST), link aggregation (LACP), switch stacking or chassis‑based platforms, QoS, and high‑availability access and distribution designs.
• Strong experience designing, deploying, and optimizing enterprise wireless networks, including RF planning, capacity management, and performance troubleshooting.
• Advanced experience with Cisco Identity Services Engine (ISE), including policy implementation, troubleshooting complex authentication and authorization issues, and integration with enterprise identity systems.
• Demonstrated expertise in network automation and infrastructure‑as‑code practices using Python, YAML, Ansible, and related tooling.
• Experience engineering and supporting data center switching environments, including hands‑on experience with Cisco Application Centric Infrastructure (ACI), such as fabric operations, endpoint groups (EPGs), contracts, and policy…
