Priority skills for screening: SD-WAN architecture (Versa preferred), Zscaler, enterprise network design, and OT/LAN architecture exposure.

Key Responsibilities

1. Network & Infrastructure Solution Architecture

- Design and develop end-to-end enterprise network and infrastructure solutions aligned with business and technical requirements.
- Define target-state architectures, high-level designs (HLDs), low-level designs (LLDs), and solution architecture documents.
- Develop scalable, resilient, and secure network architectures for data centers, enterprise campuses, branch offices, and distributed environments.
- Evaluate existing network infrastructure and recommend modernization, optimization, and transformation strategies.
- Define network topology, connectivity, routing, switching, redundancy, and high-availability strategies.

2. SD-WAN Architecture & Implementation

- Design and architect enterprise SD-WAN solutions for branch connectivity, data centers, and cloud environments.
- Demonstrate a robust understanding of SD-WAN architecture, deployment models, traffic engineering, application-aware routing, and centralized policy management.
- Experience with Versa SD-WAN is highly desirable.
- Define SD-WAN migration strategies, implementation roadmaps,



and coexistence models with existing WAN infrastructure.
- Integrate SD-WAN with security, cloud connectivity, and enterprise network services.
- Assess network performance, resiliency, bandwidth utilization, and application experience.

3. Zscaler & Network Security

- Design and integrate secure network access solutions using Zscaler technologies.
- Exposure to Zscaler Zero Trust Exchange, Zscaler Internet Access (ZIA), and Zscaler Private Access (ZPA).
- Understand Zero Trust Network Access (ZTNA), Secure Web Gateway (SWG), Secure Access Service Edge (SASE), and Security Service Edge (SSE) architectures.
- Define secure connectivity patterns for users, branches, applications, and cloud workloads.
- Work with security teams to align network architecture with enterprise security policies and compliance requirements.

4. OT/LAN Architecture

- Develop and review Operational Technology (OT) and enterprise LAN architecture.
- Understanding of the Three S approach to OT/LAN is desirable.
- Assess OT/LAN network segmentation, security zones, connectivity, and operational requirements.
- Define secure and resilient network designs for IT and OT environments.
- Support the integration of OT environments with enterprise network and security architectures.
