Fastly

The 2024 program placed twelve interns across engineering teams - observability, edge protocols, cache, traffic management, monetization, NetOps, domain services (TLS), Varnish, API services and others - with project work delivered from the San Francisco headquarters and the New York office. Published listings for the role describe a twelve-week paid program running across the summer. The intake is small and team-allocated, so a candidate is not applying to a generic intern pipeline but to a specific engineering function; the prep that pays off is depth in that function rather than a general analyst-style application.

Fastly's company page and independent profiles such as Wikipedia describe a small set of architectural choices that set it apart:

• Founded in 2011 by Artur Bergman around a programmable, Varnish-based edge network
• Public on the New York Stock Exchange under the ticker FSLY since May 2019
• A deliberately fewer-but-more-powerful POP architecture, with stated edge capacity above 570 Tbps and Instant Purge that clears cached content globally in under roughly 150 ms
• Compute, a serverless edge runtime (originally launched as Compute@Edge in 2019) that lets customers run their own code at the network edge

For an early-career engineer the implication is concrete: the day-to-day work is closer to networking, systems and runtime engineering than to typical web-application backend work, and the prep that maps onto it is operating-systems and HTTP fundamentals rather than CRUD frameworks.
