Key responsibilities
Architecture and roadmaps
· Define enterprise network reference architectures, standards, and patterns for campus/branch, data center, cloud connectivity, and remote access.
· Own L2/L3 designs (BGP, OSPF, VRF, route-maps, NAT, QoS) with an emphasis on high availability, segmentation, and zero-trust principles.
· Develop multi-year technology roadmaps and capacity plans; drive lifecycle management and refresh strategies.
SD-WAN (HPE Aruba EdgeConnect)
· Design and optimize underlay/overlay, path conditioning, segmentation, and business intent policies.
· Establish best practices for active/active paths, performance monitoring, and failover; integrate with MPLS/Internet and cloud on-ramps.
Cisco enterprise and Meraki
· Lead designs for campus/branch switching and routing (Catalyst/IOS-XE) and Meraki (switching, MX, wireless).
· Establish segmentation strategies (VRF/VLAN, SGTs if applicable), QoS, and resiliency (HSRP/VRRP, ECMP).
Identity and NAC (Cisco ISE)
· Architect and operationalize 802.1X/MAB, profiling, posture, guest/BYOD, and device onboarding.
· Define policies for dynamic VLANs, SGT/TrustSec (if used), and certificate/PKI integrations; ensure smooth enforcement across Cisco and Meraki.
Data center networking
· Design and maintain data center fabrics and core switching (e.g., Cisco Nexus/leaf-spine or equivalent), L2/L3 redundancy, and EVPN/VXLAN or traditional designs as applicable.
· Integrate firewalling, load balancing, and private/public cloud connectivity.
Monitoring, telemetry, and tooling
· Set standards for observability (SNMP/telemetry, syslog, NetFlow/IPFIX), dashboards, and alerting.
· Leverage and integrate tools such as SolarWinds/Orion, NetFlow/IPFIX collectors, packet capture/analysis (e.g., Wireshark), and configuration/asset platforms.
· Define SLOs/SLIs and use data to drive capacity planning and problem management.
Security, compliance, and governance
· Embed security and regulatory best practices applicable to financial services into network designs (segmentation, encryption, access controls, logging/retention, change control).
· Partner with Security, Compliance, and Audit to meet policy and regulatory expectations.
Delivery and operations
· Provide L4/L5 escalation support; lead root-cause analysis and corrective action plans for major incidents.
· Author high-quality documentation: HLDs/LLDs, standards, runbooks, and diagrams.
· Participate in CAB/ITIL processes; plan and execute complex changes, including after-hours maintenance windows.
Collaboration and leadership
· Mentor engineers, review designs, and raise the bar for engineering quality.
· Engage with vendors, evaluate solutions, and contribute to budgeting and SOWs.
· Translate business requirements into robust technical solutions and clear deliverables.
Required qualifications
· 8–10+ years of progressive experience designing and operating large enterprise networks; 3+ years in an architecture or principal engineering role.
Deep hands-on expertise with:

· HPE Aruba/Aruba EdgeConnect SD-WAN certifications (Professional/Expert level).
· ITIL Foundation.
· Network automation and IaC experience (e.g., Python, Ansible, REST APIs, Git) and familiarity with source control and CI/CD practices.
· Cloud networking exposure (Azure/AWS/GCP routing, VPN/SD-WAN/cloud interconnects, virtual appliances).
· Experience with DNS/DHCP/IPAM, CMDB, and source-of-truth platforms.
Education
· Bachelor’s degree in Computer Science, Engineering, Information Systems, or equivalent practical experience.
Work conditions
