What success looks like in this role:
Own and lead end-to-end network architecture for large, complex customer environments, including multi-site, hybrid, multi-cloud, and regulated ecosystems.
Drive architecture discovery through comprehensive current-state assessments, application dependency mapping, traffic flow analysis, capacity baselining, and risk evaluation.
Develop high-quality architectural deliverables, including:
High-Level and Low-Level Designs (HLD/LLD)
Reference architectures and reusable design patterns
Logical and physical diagrams
Segmentation strategies and routing/switching frameworks
Security and resiliency architectures (fault domains, high availability, disaster recovery)
Bills of materials, licensing alignment, and cost/risk trade-off analysis
Define and validate future-state architectures across:
Data center, campus, WAN, and branch environments
SD-WAN, SASE, and ZTNA integrations
Load balancing (L4/L7), DNS/DHCP/IPAM (DDI)
NAC, segmentation, and micro-segmentation (as applicable)
IPv4/IPv6 strategy, BGP/OSPF/ISIS, and EVPN/VXLAN where required
Ensure all designs align with business objectives, including growth initiatives, M&A activity, regulatory compliance, cloud adoption, user experience, and cost optimization.
Maintain hands-on credibility by validating designs through configuration prototypes, lab testing, packet captures, and live-environment troubleshooting.
Lead initiatives to stabilize and mature network operations by implementing:
Standard operating procedures, runbooks, and defined escalation paths
Incident reduction programs leveraging root cause analysis (RCA) and structured problem management
Formal change governance with standardized templates, risk scoring, and rollback strategies
Configuration standardization (golden configurations, compliance validation, drift detection)
Resiliency improvements through SPOF elimination, HA consistency validation, and failover testing
Develop and execute a Network Reliability Plan with measurable outcomes:
Improved availability and reduced downtime
Reduced MTTR
Lower change failure rates
Alert noise reduction
Performance SLOs (latency, jitter, packet loss) aligned to application requirements
Establish strong Day-2 operational readiness by implementing:
Monitoring and telemetry baselines (SNMP, streaming telemetry, syslog, NetFlow)
Event correlation and service mapping
Capacity forecasting and lifecycle management
Drive post-implementation validation through performance testing, failover validation, and formal operational acceptance criteria.
Serve as a trusted technical advisor to executive stakeholders (CIO, CTO, CISO, VP Infrastructure/Operations).
Lead executive workshops and translate technical strategy into business outcomes, including:
Risk posture and resiliency strategy
Compliance readiness
CapEx/OpEx optimization and vendor strategy
Cloud and network roadmap alignment
Present architectural decisions with clearly articulated trade-offs:
Option comparisons (cost, risk, complexity, time-to-value)
Explicit assumptions and constraints
Clear, defensible recommendations
Own the technical narrative in high-impact forums such as QBRs, EBRs, steering committees, architecture review boards, and executive incident briefings.
Provide architectural governance throughout the delivery lifecycle.
Review designs for accuracy, scalability, security, and operational readiness
Ensure implementation fidelity to architectural intent
Lead technical checkpoints (design reviews, pre-change readiness, go/no-go decisions)
Define and enforce quality standards for:
Implementation best practices and validation checklists
Documentation completeness and operational handoff
Functional, performance, and failover testing
Partner with Program Managers and Delivery Leads on scope definition, sequencing, dependency management, risk mitigation, and cutover strategy planning.
Serve as the highest-level escalation point for complex network issues, including:
Routing instability, BGP/OSPF anomalies, asymmetry, STP/loop conditions
MTU/fragmentation challenges, application timeouts, TLS impacts
WAN/ISP/cloud edge packet loss and jitter root cause analysis
Firewall/NAT conflicts and segmentation misalignment
Lead major incident bridge calls and coordinate cross-functional teams including network, security, compute, storage, applications, ISPs, and cloud providers.
Apply evidence-based troubleshooting using packet captures, flow analytics, logs, telemetry, traceroutes, and synthetic testing. Translate deep technical findings into concise, executive-ready summaries.
Embed security into architecture and operational practices through:
Segmentation and least-privilege connectivity models
Secure management plane architecture (MFA, AAA, TACACS/RADIUS)
Logging, auditability, and compliance alignment
Design in accordance with applicable frameworks such as Zero Trust principles and regulatory control models (PCI, HIPAA, SOX, FedRAMP-like requirements).
Ensure secure remote access and third-party connectivity architectures.
Drive enterprise-wide network engineering standards, including:
Architecture standards and naming conventions
IP schema governance, BGP community design, QoS strategy
Lifecycle management including EOL/EOS tracking and refresh planning
Promote automation and operational efficiency through:
Infrastructure as Code (Ansible, Terraform) where appropriate
Configuration templates and compliance guardrails
Repeatable, automated deployment pipelines
Mentor senior engineers and architects to elevate architectural quality and consistency. Lead communities of practice and provide technical enablement, training, and reusable design frameworks. Set technical direction across multiple programs and internal initiatives. Influence stakeholders across sales, delivery, and operations—driving alignment without formal authority.
