Senior Network Architect

What Success Looks Like In This Role

• 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, M&A, 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.

• 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.
• Executive / C-Level Customer Engagement & Technology Leadership (Primary)
• 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)

• Delivery Oversight & Technical Governance (Primary)
• 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

• Hands-On Technical Troubleshooting & Escalation Leadership (Primary)
• 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.
• Security, Compliance & Risk Integration (Key)
• 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

• Standardization, Automation & Best Practices Enablement
• 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

• Mentorship, Leadership & Cross-Functional Influence
• 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.
