Senior Cisco Network Engineer

Overview

• Provide Network Engineering support for all network segments and applications.
• Act as L2/3 escalation for P1/P2 incidents; lead triage, stabilization, and post‑incident RCA with clear corrective actions.
• Troubleshoot advanced routing, switching, wireless, firewall, load balancing, and VPN issues across multi‑vendor environments.
• Optimize performance (QoS, congestion control, path selection) and reduce chronic incident recurrence.
• Design and implement high‑availability network architectures (redundant core/edge, SD‑WAN, data center fabrics, segmentation).
• Own changes from design review through implementation and validation, aligning with GxP/GMP change control and documentation.
• Enforce network security baselines (micro‑segmentation, NAC, firewall policies, IDS/IPS, secure VPN, certificate management).
• Collaborate with InfoSec on risk assessments, hardening, and compensating controls.
• Manage and optimize connectivity to public cloud (Azure/AWS): ExpressRoute/Direct Connect, hybrid routing, private endpoints.
• Support SD‑WAN policy design, traffic steering, and cloud edge security integration.

• Maintain robust observability (SNMP, flow telemetry, synthetic tests, packet captures, logs, NPM/APM tools).
• Utilize NPM tools (e.g., SolarWinds, ThousandEyes), packet capture (Wireshark), NetFlow/sFlow/IPFIX, syslog/SIEM – or similar tools
• Build automation for configuration compliance and repeatable changes (e.g., Ansible/Netmiko/Python), including templating and guardrails.
• Author and maintain network standards, runbooks, validated configurations, and diagrams (as‑built/target state).
• Execute ITIL processes (Incident, Problem, Change, Configuration Management) with precise records suitable for audits.
• Mentor L1/L2 engineers; provide technical guidance and training.
• Partner with OT, Lab IT, Manufacturing, Application, and Security teams to deliver solutions aligned to business and regulatory needs.
• Ability to rack/stack equipment and work in data center/lab/manufacturing areas with appropriate PPE.
• Work with cross-functional teams to design solutions for expanding connectivity while maintaining overall network performance and integrity.

• Security: Experience with firewalls (e.g., Palo Alto, Fortinet, Check Point), VPN/IPsec/SSL, IDS/IPS, micro‑segmentation, ACLs, NAT, secure management (SSH/TLS/SNMPv3).
• Wireless/NAC: Enterprise WLAN (controllers, RF design, WPA2‑Enterprise/802.1X), NAC (e.g., Cisco ISE), role‑based access policies.
• SD‑WAN: Policy‑based path selection, application steering, HA design, integration with cloud edges.
• Load Balancing: F5/NGINX/AVI or equivalent for L4–L7 services, TLS offload, persistence, health monitors.
• Cloud Networking: Azure VNets, VNet peering, Private Link/ExpressRoute; AWS VPCs, TGW, Direct Connect; hybrid routing and security patterns.
• Experience with zero‑trust network principles, micro‑segmentation platforms, and certificate/PKI operations.
• Observability: Hands‑on with NPM tools (e.g., SolarWinds, ThousandEyes), packet capture (Wireshark), NetFlow/sFlow/IPFIX, syslog/SIEM.
• Automation/Scripting: Practical experience with Ansible and Python for network tasks (templates, compliance checks, bulk updates).
• Process: ITIL familiarity and disciplined change management in 24x7 production settings.
• Soft Skills: Clear communicator, calm under pressure, able to lead incidents and influence cross‑functional teams.
