Position Summary

The Senior Content Delivery Network Engineer is responsible for the design, implementation, optimization, and operational reliability of enterprise Content Delivery Network (CDN) platforms supporting large-scale, customer-facing digital applications. This role drives the delivery of secure and highly available content by managing CDN configurations, caching strategies, traffic routing, and edge security controls across distributed environments. The position plays a critical role in improving end-user experience and ensuring resilient application delivery through continuous performance tuning and data-driven optimization.

This role serves as the technical owner and subject matter expert for CDN technologies, partnering with applications, network, and security teams to implement scalable solutions and enforce enterprise standards. The Senior CDN Engineer is accountable for automation of CDN operations, incident response and root cause analysis, and ongoing platform improvements, including emerging edge capabilities and security enhancements. Through hands-on engineering, operational leadership, and strategic contribution, the role supports the organization’s broader goals of reliability, scalability, cost efficiency, and secure digital delivery.

Role Responsibilities:

Development & Enforcement

• Design, implement, and enforce enterprise-wide CDN standards, policies, and best practices.
• Develop scalable automation frameworks using tools such as Python, Terraform, and GitOps to streamline CDN configuration management.
• Ensure consistency in security configurations, caching strategies, and routing policies across environments.

Collaboration & Expertise

• Partner with application teams, network engineers, and security stakeholders to design and implement optimized CDN solutions.
• Act as a subject matter expert (SME) for CDN technologies including Akamai, Cloudflare and AWS CloudFront.
• Provide consultation on reference architectures and deployment strategies for enterprise programs.
• Act as a strong team player by partnering with peer engineers and stakeholders to drive end-to-end delivery, ensuring alignment with business goals, timelines, and technical standards.

Analysis & Configuration

• Configure, optimize, and maintain CDN platforms to improve latency, throughput, availability, and user experience.
• Implement advanced CDN features such as bot management, DNS configurations, API acceleration, and caching strategies.
• Analyze performance data and optimize SEO and web performance through CDN enhancements.
• Fine-tune cache behaviors, routing rules, load-balancing, and WAF policies.
• Develop incident response and recovery strategies and able to create on demand RCA’s.
• Investigate complex delivery issues using traffic analysis, HAR traces, Akamai debug headers, log correlation, and origin/CDN handshake validation to isolate edge, DNS, TLS, and application-layer faults.

Operational Support

• Provide L3 support, including incident triage, troubleshooting, and root cause analysis and applying timely fixes for CDN-related issues.
• Participate in on-call rotations, ensuring availability during late-night production releases.
• Maintain high system reliability through proactive monitoring and incident prevention.
• Must troubleshoot advanced DNS and traffic management configurations using Akamai GTM and Edge DNS.
• Establish and track CDN-specific SLOs/SLAs (latency, cache hit ratio, error rates) and implement alerting and proactive remediation.

Mentorship & Training

• Mentor junior engineers and provide guidance on CDN best practices, automation, and troubleshooting techniques.
• Develop internal documentation, playbooks, and training materials to elevate team capabilities.

Innovation and Research

• Evaluate emerging CDN technologies, tools, and performance optimization techniques.
• Drive continuous improvement initiatives in automation, observability, and security.
• Explore new capabilities in edge computing, serverless CDN features, and API acceleration.

Strategic Planning

• Contribute to long-term CDN roadmap and architecture strategy aligned with enterprise goals.
