Inside Fastly’s 2026 Internship Program: Projects, Impact & Culture

Fastly’s fourth internship cohort for Summer 2026 contributed production-focused projects across engineering, network operations, security, developer tools, and UX, reflecting the company’s emphasis on hands-on work for early-career talent. Interns modernized internal cloud-cost and feature-flag systems, created network transit scoring and DNS-utilization tools, improved peering automation, developed Go microservices for infrastructure and service configuration, expanded local caching tests in Viceroy, and applied machine learning to bot detection and web application firewall false-positive mitigation. Their work aimed to improve operational efficiency, reliability, security, developer workflows, customer experience, and cost management. Participants described a supportive culture marked by mentorship, collaboration, access to experienced engineers, social events, and opportunities to deploy meaningful code, while advising future interns to ask questions, study documentation and source code, seek feedback, build connections, track project milestones, and focus on measurable impact.
