Description : Job Description :
Lead 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 Responsibilities
- Own 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 Skills
Customer 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 / KPIs
Solution 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).#LI-KR2
