• Generate and deploy F5 configurations, Palo Alto firewall rules, and Cisco ACI policies through Ansible, Python, Terraform, and/or API-driven automation.

• Implement CI/CD pipelines to validate and roll out network and security changes safely and repeatably.

• Implement and support network segmentation strategies for zero-trust architectures and compliance mandates.

• Oversee incident response and escalation workflows, ensuring timely resolution and stakeholder communication.

• Maintain DNS (BIND), IPAM, and domain name services across enterprise environments with automation-first principles.

• Support branch office automation initiatives using Cisco DNA Center and other vendor platforms.

• Deploy Cisco ACI fabric including spine-leaf topology, APIC controllers, and policy-based configurations.

• Configure multi-pod and multi-site Cisco ACI environments for scalability and redundancy.

• Implement L4-L7 service insertion using service graphs and contracts.

• In-depth understanding of Linux networking, kernel-based switching, and open-source routing stacks (FRR, BIRD, and Quagga).

• Proven experience developing and deploying infrastructure-as-code for network and security platforms (Ansible, Terraform, Git, YAML, JSON).

• Experience automating configurations and policy enforcement across:

• Cisco ACI and DNA Center

• F5 load balancers (iControl REST, AS3 templates)

• Palo Alto firewalls and Panorama (REST and XML APIs)

• Proficiency in routing and overlay technologies (BGP, EIGRP, VXLAN/EVPN, OSPF, etc) and switching.

• Experience in SDWAN deployments and support.

• Understanding of network segmentation, zero-trust access, and security frameworks.

• Familiarity with cloud networking platforms including AWS Direct Connect, Azure ExpressRoute, and hybrid/on-prem cloud solutions.

• Experience with packet capture analysis, network monitoring, performance tuning, and capacity planning.

• Strong organizational and communication skills, with the ability to manage multiple priorities and stakeholders.

• Ability to foster effective working relationships across global teams and drive consensus in complex environments.

Qualifications

• Bachelor's degree in Computer Science, Electrical/Computer Engineering, Information Systems, or equivalent practical experience.
• Minimum of 7 years of progressive experience in network engineering, architecture, and support.
• Minimum of 3 years hands-on experience with software-defined networking, Linux, and infrastructure as code methodologies.
• Certifications:
• Cisco (CCNA/P), cross-platform automation and/or Linux certifications preferred but not required
