Network Solution Architect

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.

Role & 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.
