About the job

We are seeking a Senior Network Architect with deep, hands-on expertise in end-to-end network solutioning across the modern enterprise stack — Software-Defined LAN, SD-WAN, SASE, application delivery (load balancing), DDI, and Software-Defined Data Center LAN. The role owns the technical design and architecture of complex, multi-vendor network solutions from concept through to detailed design and handover, translating business and security requirements into resilient, scalable, and automatable architectures.

This is a senior individual-contributor / technical-authority role that blends solution design, pre-sales/solutioning support, standards definition, and mentoring. You will be the go-to authority on network design decisions, reference architectures, and technology selection, working closely with delivery teams, security, cloud, customers, and OEM partners. The role also increasingly requires fluency in AI — both applying AI/AIOps to operate and optimize networks, and designing networks that support AI/ML workloads.

Responsibilities

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.
