Overview:
Our client is seeking a highly experienced Senior Network Engineer to lead the design and deployment of Cisco ACI and SD-Access solutions across campus and data center environments. This individual will play a pivotal role in enabling end-to-end segmentation and access control by integrating Cisco ACI, ISE, and DNA Center within a unified enterprise network fabric.

Key Responsibilities:

• Lead the design, configuration, and deployment of Cisco ACI fabric, including application profiles, endpoint groups (EPGs), and contracts.
• Architect and implement SD-Access across campus environments, integrating with Cisco DNA Center and ISE for identity-based access and policy enforcement.
• Develop and execute ACI segmentation strategies, including mapping user groups and endpoints using security group tags (SGTs) from ISE.
• Ensure seamless integration of campus switching, desktop VLANs, and data center networks within the ACI-based fabric.
• Oversee end-to-end segmentation and access control, from wired/wireless edge through the core network to the data center.
• Collaborate with security, desktop, and application teams to align segmentation with organizational access policies.
• Provide troubleshooting, optimization, and ongoing support for the ACI/SD-Access environment.
• Mentor junior engineers and lead cross-functional project efforts.

Required Qualifications:

• 8+ years in enterprise networking, with deep, hands-on experience in Cisco ACI.
• Strong expertise with Cisco ISE, Cisco DNA Center, and SD-Access deployments.
• Demonstrated experience with ACI segmentation design and implementation (SGTs, EPGs, contracts).
• Proficient in campus switching (Catalyst/Nexus) and integrating wired/wireless access into ACI fabric.
• Familiarity with enterprise security and access control principles.
• Strong understanding of L2/L3 protocols, routing, and multicast within ACI fabrics.
• Ability to lead projects independently, work cross-functionally, and communicate clearly with technical and non-technical stakeholders.

Preferred:

• Cisco certifications (e.g., CCNP, CCIE, Cisco Certified Specialist – ACI or SD-Access)
• Experience with automation via Python, Ansible, or Cisco APIs
• Familiarity with hybrid cloud or multi-site ACI environments
