About this role
1) Customer Network Architecture End-to-End Design Leadership (Primary)
- Own the end-to-end network architecture for large/complex customer environments (multi-site, multi-cloud, hybrid, regulated).
- Lead architecture discovery: current-state analysis, application dependency mapping, traffic flows, capacity baselining, and risk assessment.
- Produce high-quality architecture artifacts, including:
- High-level and low-level designs (HLD/LLD)
- Reference architectures and patterns
- Logical/physical diagrams, segmentation models, routing switching plans
- Security and resiliency designs (fault domains, HA, DR)
- Bill of materials, licensing alignment, and cost/risk trade-offs
- Define and validate target-state architecture across:
- Data center campus WAN branch
- SD-WAN, SASE, ZTNA integration
- Load balancing (L4/L7), DNS/DHCP/IPAM
- DDI, NAC, segmentation, micro-segmentation (where applicable)
- IPv4/IPv6 strategy, BGP/OSPF/ISIS, EVPN/VXLAN (if required)
- Ensure designs align to customer business outcomes (growth, MA, compliance, cloud adoption, user experience, cost controls).
Hands-on expectation: Ability to validate designs via config prototypes, lab testing, packet capture, and troubleshooting in real environments.
2) Operational Stabilization Network Reliability Excellence (Primary) - Lead the stabilization of network operations by establishing and driving:
- Operational maturity (standard operating procedures, runbooks, escalation paths)
- Incident reduction program using RCA, problem management, and corrective action plans
- Change governance with standardized change templates, risk scoring, and backout plans
- Configuration standardization (golden configs, compliance checks, drift detection)
- Resiliency improvements: elimination of SPOFs, HA consistency, redundancy validation, failover testing
- Create a Network Reliability Plan with measurable targets:
- Availability downtime reduction
- MTTR improvement
- Change failure rate reduction
- Alert noise reduction
- Performance SLOs (latency/jitter/loss) aligned to app needs
- Build Day-2 Operations readiness:
- Monitoring/telemetry baselines (SNMP/streaming telemetry/syslog/NetFlow)
- Event correlation and service mapping
- Capacity forecasting and lifecycle management
- Drive post-implementation validation: performance testing, failover testing, and operational acceptance criteria.
- Act as the trusted technical advisor to customer executives (CIO, CTO, CISO, VP Infrastructure/Operations).
- Lead executive-level workshops and steer conversations from technical detail to business outcomes:
- Risk posture, resiliency, compliance readiness
- Cost optimization (CapEx/OpEx), vendor strategy, roadmap planning
- Cloud/network strategy alignment
- Present architectural decisions with clear trade-offs:
- Option A vs B cost, risk, complexity, time-to-value
- Explicit assumptions, constraints, and recommended path
- Own the technical narrative in high-stakes settings:
- QBRs/EBRs, steering committees, architecture review boards
- Critical incident executive briefings (what happened, impact, mitigation, prevention)
- Provide architectural governance across the delivery lifecycle:
- Review designs for correctness, security, scalability, and operational readiness
- Ensure implementation matches the design intent
- Lead technical checkpoints: design review, pre-change readiness, cutover go/no-go
- Define quality bars for:
- Implementation standards and validation checklists
- Documentation completeness and operational handover
- Testing requirements (functional, performance, failover)
- Partner with PMs and Delivery Leads on:
- Scope definition, sequencing, risk and dependency management
- Technical change windows and cutover strategy
- Serve as top-tier escalation for complex issues:
- Routing instability, asymmetry, BGP/OSPF issues, STP/loop events
- MTU, fragmentation, application timeouts, TLS handshake impacts
- Packet loss/jitter root causes across WAN/ISP/cloud edges
- Firewall policy conflicts, NAT issues, segmentation misalignment
- Lead bridge calls during major incidents; coordinate across teams/vendors:
- Network, security, compute, storage, application, ISP, cloud providers
- Use evidence-based troubleshooting:
- Packet captures, flow analytics, logs/telemetry, traceroutes, synthetic tests
- Translate technical root cause into executive-ready summaries.
- Ensure security is built into architecture and operations:
- Segmentation strategy, least privilege connectivity patterns
- Secure management plane, MFA/AAA, TACACS/RADIUS
- Logging, auditability, and compliance controls alignment
- Align designs with common requirements (as applicable):
- Zero Trust principles, PCI/HIPAA/SOX/FedRAMP-like control expectations
- Secure remote access and third-party connectivity patterns
- Drive adoption of network engineering best practices:
- Architecture standards, naming conventions, IP schema, BGP communities, QoS strategy
- Lifecycle standards: EOL/EOS tracking and refresh planning
- Enable automation and reduce manual work:
- Infrastructure as Code where practical (Ansible/Terraform)
- Configuration templates, compliance guardrails, repeatable build pipelines
- Mentor senior engineers and architects; elevate overall architecture quality.
- Lead communities of practice; provide technical training and design patterns.
- Set technical direction across multiple customer programs and internal initiatives.
- Influence stakeholders without direct authority; drive alignment across sales, delivery, and operations.
