It is ideal for someone with deep experience in building scalable middleware solutions, a solid foundation in JavaScript/TypeScript, and a passion for optimizing edge performance at scale.

• Contribute to architectural decisions alongside staff and distinguished engineers
• Collaborate cross-functionally with product, DevOps, security, and platform teams
• Ensure CDN configurations adhere to performance, security, and availability standards
• Monitor, debug, and optimize caching strategies and edge delivery pipelines
• Evaluate and recommend improvements to CDN observability and edge performance tooling
• Actively participate in peer code reviews, providing feedback to your fellow engineers to make them better and to improve the quality of the software we ship
• Provide technical support to product teams, advising on best practices and highlighting risks
• Engage in continuous improvement projects within the team

• 3+ years of experience delivering projects from inception to completion, demonstrating ownership and accountability throughout the entire project lifecycle

Preferred Qualifications

• Experience with edge computing platforms
• Knowledge of Layer 7 routing, WAFs, and edge security patterns
• Experience integrating observability tooling (e.g., logging, metrics, tracing) into CDN workflows
• Strong awareness of web performance optimization techniques (e.g., Lighthouse, Core Web Vitals)
• Exposure to infrastructure-as-code tools (e.g., Terraform or Deployment Manager
• Experience working on a project using mature CI/CD practices
• Exposure to DevOps tools, processes, and culture (e.g., Kubernetes, Docker, CircleCI, Git, GitHub Actions, Gitlab runners, etc.)
• Ability to drive architecture and design decisions in collaboration with more senior level (staff, principal, distinguished) engineers
• Familiarity with web application performance and delivery at the edge
• Experience working with a source versioning tool, such as Git
• Experience working as a member of an Agile software development team
