• Build and maintain infrastructure using AWS Cloud Development Kit (CDK) in TypeScript

• Improve platform resilience, scalability, and performance across global regions

• Implement protections against large-scale attacks (e.g. DDoS, traffic spikes, abusive patterns)

• Analyze traffic behavior and continuously optimize caching, routing, and security policies

• Contribute to standardization and automation of global public infrastructure

• Collaborate closely with engineering teams to support secure and performant delivery of web applications

Highly Valuable Experience

• Operating high-volume commercial or consumer-facing web platforms

• Edge performance engineering and latency optimization

• Advanced caching strategies and origin shielding

• Security engineering at CDN / edge layer
