ICT Infrastructure Engineer

Key Responsibilities:

Network Transformation Architecture

• Lead the design, engineering, and execution of next-generation network transformation solutions
• Collaborate with internal teams, including cloud, security, and application stakeholders, to align network infrastructure with business needs
• Provide technical leadership in building highly resilient, scalable, and secure hybrid/multicloud network environments

Design, Deployment, and Operations

• Architect and deploy advanced Cisco ACI infrastructure across active-active datacenters
• Integrate ACI with hybrid cloud and multicloud environments to ensure seamless connectivity and performance
• Manage day-to-day operations, monitoring, and troubleshooting of ACI fabric components
• Collaborate with vendors, Cisco TAC, and internal teams to resolve complex network incidents and escalations

Policy Management and Automation

• Develop and implement policy-driven network architectures using Cisco ACI’s capabilities
• Utilize automation tools (e.g., Ansible, Python) to streamline network operations and ensure efficiency
• Ensure network policies align with industry best practices and compliance requirements

Documentation and Governance

• Maintain accurate network diagrams, policy documentation, and technical procedures
• Ensure all infrastructure and operations meet internal governance and security standards

Mentorship and Knowledge Sharing

• Provide SME-level guidance to internal teams and mentor junior network engineers
• Lead knowledge transfer sessions to enhance team capabilities in ACI and related technologies

Requirements:

• A bachelor’s or master’s degree and 10-15 years of experience in core Network technologies with at least 5 years focused on Cisco ACI

Deep knowledge of Cisco ACI components and concepts:

• Fabric Architecture: Spine-Leaf topology, Fabric Discovery, and Fabric Access Policies
• Application Policy Infrastructure Controller (APIC): Clustering, APIs (REST, XML, JSON), and GUI management
• Endpoint Groups (EPGs), Contracts, and Filters: Policy-based connectivity and segmentation
• Tenant Model: VRFs, Bridge Domains, and Layer 2/3 connectivity across multiple tenants
• ACI Multi-Site and Multi-Pod deployments
• Integration with L4-L7 services (e.g., firewalls, load balancers) using Service Graphs
• Expertise in ACI troubleshooting: Health Scores, Service Graphs, and CLI/APIC diagnostics
• Experience with Cisco Nexus Dashboard Insight for monitoring and managing ACI environments effectively

VXLAN and EVPN Expertise

• VXLAN Fabric Architecture: Understanding of VXLAN encapsulation for scalable Layer 2 and Layer 3 networks
• MP-BGP EVPN (Ethernet VPN): Control plane for VXLAN, providing seamless Layer 2 extension and optimized Layer 3 routing
• Interoperability between ACI and non-ACI environments using VXLAN/EVPN

BGP and OSPF Routing Expertise

• In-depth knowledge of BGP (Border Gateway Protocol) for managing external and internal routing policies
• Experience with BGP peering, route filtering, and path selection in complex ACI and datacenter environments
• Expertise in OSPF (Open Shortest Path First) for building dynamic Layer 3 routing in underlay networks
• Integration of BGP and OSPF within ACI fabric to manage hybrid cloud and multi-pod deployments

Solution Architect: (Preferrable)

• Solution-level understanding of Cisco ACI interoperability with firewalls (e.g., Palo Alto, Check Point, Fortinet), load balancers (e.g., F5 GTM, LTM, ASM), micro-segmentation solutions, policy enforcement, and IPAM, DNS, and DHCP systems
• Added advantage for candidates with hands-on experience integrating ACI with these solutions, though a willingness to learn and adapt to new technologies is acceptable
• Experience with Ansible, Python scripting, and ACI REST APIs for automation
• Knowledge of ACI App Center integrations and customization of ACI apps
• Experience with integrating ACI with multicloud environments (AWS, Azure, GCP)

Soft Skills

• Excellent analytical, problem-solving, and decision-making skills
• Strong communication and collaboration skills, with the ability to engage with stakeholders across departments
• Self-motivated with a continuous learning mindset and ability to work under pressure
