About

The Role  The Network team is responsible for the evolution, support, and governance of our global network infrastructure. The criticality of our network and the accelerating growth of our systems lead to complex challenges. Through innovation and agility, the team ensures our infrastructure and services stay at the forefront of the company’s needs.
What You’ll Do Here   Provide high-level technical expertise to support network operations across LAN, WAN, data center, campus, and cloud environments.
Design, implement, and support Cisco enterprise routing (BGP, EIGRP) and switching, including Cisco Catalyst and 9k series platforms.
Architect, deploy, and operate Cisco ACI (single site and multisite), including Nexus Dashboard and Nexus Dashboard Orchestrator.
Lead enterprise wireless design and operations leveraging Cisco APs and 9300 series wireless controllers; optimize coverage, capacity, and performance.
Operate and enhance Cisco Catalyst Center for network assurance, automation, and lifecycle management.
Implement and administer Cisco Identity Services Engine (ISE) for TACACS+, RADIUS, and 802.1X network access control across wired and wireless.
Manage Infoblox DDI services (DNS, DHCP, IPAM) and integrate with network provisioning workflows.
Provide guidance and best practices for networking in major cloud platforms (GCP, AWS, Azure), including hybrid connectivity, routing, and segmentation.
Design, implement, and optimize application delivery and load balancing solutions using Net Scaler ADC or F5 BIG-IP (or similar), ensuring high availability, performance, resiliency, and security for web and application services.
Configure L4/L7 policies: content switching, persistence, health checks, SSL/TLS offload, certificate lifecycle, ciphers, and security hardening.
Implement and tune advanced features such as GSLB, HA, responder/rewrite policies, caching, compression, and rate limiting; integrate with authentication and SSO (LDAP/AD, SAML, OAuth).
Monitor and troubleshoot performance using platform analytics (eg App Flow/HDX Insight), logs, and external APM/NPM tools; drive root cause analysis for incidents.
Develop and maintain network and application delivery automation using Python and Ansible; leverage REST APIs/CLI, version-controlled templates, and CI/CD pipelines for repeatable deployments.
Ensure engineering patterns meet SLA/availability, performance, and resiliency requirements; contribute to capacity planning and lifecycle refresh.
Write and review change requests and methods of procedure MoPs; conduct impact analysis, staged testing, and post-implementation verification.
Produce and maintain documentation (network and ADC diagrams, standards, inventories, runbooks) and leverage monitoring/resource management tools.
Collaborate with application, security, and cross-functional teams to plan changes, enforce standards, and execute releases with low risk.
Participate in an on-call rotation to ensure 24x7x365 coverage for critical infrastructure; overtime may be required during emergencies.
What You Bring To The Table   Degree or Diploma in Networking or Technology.
10+ years of experience in IP-based environments; exposure to mission-critical enterprise networks.
Hands-on experience with Cisco routing and switching (BGP, EIGRP), Cisco Catalyst and 9k series switches.

Experience with Cisco ACI (single site and/or multisite), Nexus Dashboard, and Nexus Dashboard Orchestrator.

Experience with enterprise wireless (Cisco APs, 9300 series controllers), RF design principles, and performance optimization.
Familiarity with Cisco Catalyst Center for assurance, automation, and configuration management.
Practical experience with Cisco ISE (TACACS+, RADIUS, 802.1X) and NAC policy deployment.

Experience with Infoblox DDI (DNS, DHCP, IPAM) administration.
Working knowledge of cloud networking (GCP, AWS, Azure): VPC/VNet design, routing, hybrid connectivity (VPN/Direct Connect/Express Route), and segmentation.
Strong expertise in L4–L7 load balancing and application delivery with Net Scaler ADC (MPX/VPX/CPX) or F5 BIG-IP (LTM/GTM/ASM), including SSL/TLS, WAF features, and traffic steering.
