Job description

Own the end-to-end architecture and solution design for enterprise network programs spanning campus/LAN, WAN, data center, cloud, and security-edge (SASE) domains.

• Produce High-Level Designs (HLD), Low-Level Designs (LLD), reference architectures, and design standards, including topology diagrams, IP/routing schemes, migration plans, and bill of materials.
• Lead technology evaluations, PoCs, and OEM/vendor selection, comparing solutions against functional, commercial, operational, and security criteria.
• Support pre-sales and solutioning activities — respond to RFPs/RFIs, size and cost solutions, present designs to customers and executives, and defend design decisions in technical reviews.
• Define transformation and migration strategies for legacy-to-software-defined transitions (e.g., traditional WAN → SD-WAN/SASE, classic DC → spine-leaf fabric, campus → SD-Access/fabric).
• Embed security-by-design — micro-segmentation, Zero Trust, secure edge, and integration with the broader security architecture.
• Drive network automation and Infrastructure-as-Code adoption across designs (templating, ZTP, CI/CD for network config).
• Establish design governance — architecture review boards, design patterns, guardrails, and documentation standards.
• Provide technical leadership and mentoring to network engineers and junior architects; act as design escalation point during delivery.
• Partner with cloud, security, applications, and infrastructure teams to ensure the network architecture aligns with the wider enterprise architecture and roadmaps.
