Position Details: Solution Architect Network Transformation

Network Modernization ArchitectLead solutioning and delivery architecture for large-scale network modernization programs across WAN/LAN/WLAN and cloud networking. Own end-to-end designs for SD-WAN to SASE/Zero-Trust transitions, Network-as-a-Service (NaaS) models, multi-cloud connectivity patterns, and observability/automation, aligning to business outcomes, security, and experience (SLA/XLA).Roles and ResponsibilitiesOwn discovery, assessment and target-state reference architectures for enterprise networks (WAN/LAN/WLAN, DC/Cloud, OT/edge).Design and document HLD/LLD for SD-WAN platforms and SASE/Zero-Trust controls (SWG, CASB, ZTNA, FWaaS).Define multi-cloud networking patterns (AWS TGW/Transit, Azure vWAN/Route Server, GCP NCC) and hybrid connectivity (ExpressRoute/Direct Connect/Interconnect).Shape LAN/WLAN modernization (intent-based/SD-Access, Wi-Fi 6/6E/7) and campus segmentation with identity-aware policies.Lead PoCs and solution validation; create BOMs/BOQs, migration runbooks, fallback plans, test/UAT approaches and acceptance criteria.Partner with OEMs and Telcos; evaluate NaaS constructs and commercials; contribute to make-vs-buy decisions.Embed observability and AIOps; specify telemetry, synthetics, and experience metrics (e.g., XLA) and define SLOs/SLIs.Industrialize network automation (Ansible/Terraform, pipelines, IaC/GitOps), golden configs and compliance guardrails.Contribute to pursuits (RFI/RFP/Orals), solution narratives, effort/cost models and risk registers; ensure solution governance and sign-offs.Provide architecture oversight into delivery; guide transition, cutovers, hypercare and handover; coach architects/engineers.Author reusable patterns/accelerators and knowledge assets for the practice; evangelize TCS frameworks and best practices.Qualifications:Mandatory Skills Experience:12–18+ years in networking with 6+ years as an architect delivering global programs (>200 sites or equivalent scale).Proven track record leading assessments, roadmaps, designs and migrations for SD-WAN/SASE and campus/DC modernization. Experience in multi-vendor, multi-supplier environments; comfortable with Guardian/Service Integration models.Consulting orientation with strong client-facing communication, storytelling and executive presentation skills.Education & Certifications:Bachelor's degree in engineering/technology (or equivalent experience). One or more vendor/industry certifications: CCNP/CCIE, JNCIP/JNCIE, PCNSE, Fortinet NSE 7/8, ZIA/ZCCP, AWS Advanced Networking Specialty, Microsoft Azure Network Engineer Associate, TOGAF/ITIL (preferred).Technical Skills:Deep architecture expertise in two or more SD-WAN stacks (e.g., Cisco Viptela/Meraki, Aruba EdgeConnect, Versa, Fortinet, Palo Alto/Prisma, Juniper).Hands-on design of SASE components (SWG, CASB/DLP, ZTNA, FWaaS) with vendors such as Zscaler, Netskope, Palo Alto, Fortinet, Cisco, or Cloudflare.Cloud networking across AWS/Azure/GCP (Transit/Hub-and-Spoke, vWAN, Route Server, TGW, NCC), DNS/DHCP/IPAM (e.g., Infoblox) and identity-aware segmentation.Campus & DC networking (EVPN/VXLAN, SDA/ACI or equivalent), Wireless (Wi-Fi 6/6E/7), NAC/802.1X.Automation and IaC (Ansible, Terraform, Git, CI/CD) and scripting (Python/Bash) to codify design, config and operational workflows.Observability & Digital Experience Monitoring (e.g., ThousandEyes, AppNeta, Datadog, Dynatrace) and NPM/NPMD stacks; capacity and performance engineering.Security fundamentals: Zero-Trust architectures, micro/macro-segmentation, certificate/PKI, encryption, BCP/DR for networks.Understanding of OT/Industrial networks and Private 5G/LTE (nice-to-have) for shop-floor and edge scenarios.Desired SkillsCustomer focus and ownership mindset; ability to balance value, risk and cost.Collaborative leadership across architecture, engineering, security and operations.Structured problem-solving; crisp writing; ability to create compelling solution narratives.Success Measures / KPIsSolution quality and governance (architecture checkpoints passed, deployment exceptions).Pursuit impact (win rate/shortlists, solution scoring, commercial hygiene).Migration outcomes (cutover success rate, MTTR, performance uplift, XLA improvements).Automation and standardization (golden configs/templates; % infra as code).
