StubHub is seeking a Senior Software Engineer to join the Edge Services team, which owns the global content delivery and edge security infrastructure powering the world's leading live event marketplace. This role combines infrastructure engineering with security-focused development, working on CDN architecture, bot mitigation, fraud detection, and real-time traffic controls at massive scale.
You will design and operate AWS edge services (CloudFront, WAF, Route53, Shield, Global Accelerator) and develop scalable systems for detecting and mitigating malicious automated traffic using both commercial platforms and custom controls. Key responsibilities include codifying Infrastructure as Code (Terraform) modules to enable safe, consistent deployments; integrating fraud detection pipelines for real-time edge blocking decisions; collaborating with security and platform teams on zero-trust controls and origin shielding; and driving edge observability using metrics, traces, and logs to detect anomalies and optimize performance.
You'll also evaluate and implement emerging technologies (edge compute, rate limiting frameworks, multi-CDN failover), participate in incident response and root cause analysis, and integrate CDN and bot management coverage into existing developer platform products.
The Edge Services team treats infrastructure as a product, standardizing interfaces, applying zero-trust principles, and building scalable tooling to enable internal teams. You'll collaborate closely with Security Engineering, SRE, and product development teams to deliver best-in-class availability, reliability, and security.
Location: Hybrid (3 days in office, 2 days remote) with offices in Aliso Viejo CA, Century City CA, or New York NY.
**Requirements:**
- Expert-level experience with AWS edge and networking services (CloudFront, WAF, Route53, Shield, Global Accelerator)
- Expert-level proficiency with Terraform and infrastructure-as-code patterns in production
- Deep experience implementing or operating enterprise-grade bot management platforms (e.g., HUMAN, AWS Bot Control, Cloudflare Bot Management, Akamai Bot Manager)
- Advanced knowledge of HTTP protocol, CDN caching strategies, edge compute functions (e.g., Lambda@Edge), and TLS management
- Strong software development experience in a modern language (Python, Go, TypeScript, Java)
- Track record of building safe, observable, and performant infrastructure at scale
- Familiarity with building and scaling fraud prevention systems or integrating with fraud intelligence platforms is a plus
**Preferred Skills:**
- Experience authoring real-time request evaluation logic at the edge
- Familiarity with HTTP/2, QUIC, and emerging transport protocols for low-latency content delivery
- Familiarity with custom device fingerprinting, rate limiting, and CAPTCHA challenge orchestration
- Experience supporting traffic segmentation, geo-steering, or multi-CDN architecture
- Background in high-scale event collection and processing for edge analytics
- Proficiency in implementing defense-in-depth mechanisms for Layer 7 attacks
- Proficiency in building distributed rate-limiting or request scoring systems
- Familiarity with principles of secure system design and zero-trust architectures
- Contributions to open-source projects in the edge, networking, or observability space
