Requirements

8+ years of hands-on network engineering experience, with several years in a senior or architecture-focused role designing and supporting large-scale enterprise networks
Expert-level knowledge of routing and switching protocols including BGP, OSPF, EIGRP, EVPN/VXLAN, SD-WAN, and MPLS in multi-vendor environments
Deep experience with network security technologies and protocols including IPSec, IKE, GRE, TACACS, RADIUS, 802.1x, NAC, and EAP-TLS
Proficiency with network automation and configuration management tools such as Python, Ansible, Terraform, OpenStack, and REST APIs
Extensive hands-on experience deploying and troubleshooting Cisco routing/switching, Aruba wireless, Palo Alto firewalls, and Zscaler secure access platforms
Strong packet analysis skills using tools like Wireshark or tcpdump to diagnose root causes of performance degradation, latency, or connectivity failures
Understanding of AI and machine learning concepts as they apply to network operations, including familiarity with AI-driven anomaly detection, predictive analytics for capacity planning, and how large language models can assist with configuration generation and troubleshooting workflows
Bachelor's degree in Computer Science, Information Technology, Engineering, or equivalent practical experience

Nice To Haves

Certifications such as PCNSE, ZIA/ZPA, CCNP, CCIE, CISSP, or equivalent work experience are a strong plus
You can explain a complex BGP routing decision or firewall policy conflict to a non-technical stakeholder in two sentences without losing the nuance or oversimplifying the risk
You do not wait for a crisis to automate. You see repetitive manual tasks and build scripts, playbooks, or workflows that make the next deployment faster and more reliable
You are comfortable working after hours to support maintenance windows, upgrades, or critical incidents, and you plan those windows with enough detail that they rarely go sideways
You stay current on emerging technologies like AI-driven network operations, machine learning for anomaly detection, and large language models, and you think about how they apply to real infrastructure problems

Responsibilities

Design and architect enterprise network solutions across LAN, WAN, data center, wireless, and security infrastructure that support a global workforce and AI-driven workloads
Deploy, configure, and troubleshoot production network infrastructure using Cisco, Aruba, Versa, Palo Alto Networks, and Zscaler platforms in multi-site environments
Build and maintain automation workflows using Python, Ansible, Terraform, and REST APIs to standardize configurations, reduce manual intervention, and improve deployment speed
Lead the implementation of SD-WAN, EVPN/VXLAN, and DMVPN architectures to optimize connectivity and scalability across distributed sites
Monitor network performance and security posture, analyze packet captures to diagnose latency, packet loss, and application-layer issues, and drive resolution
Develop and maintain network documentation including architecture diagrams, configuration standards, security policies, and operational runbooks
Mentor network engineers and cross-functional IT teams, sharing knowledge on complex protocols, troubleshooting techniques, and automation best practices
