Negotiation DNA — Why This Role Commands a Premium at Fastly
This is the signature engineering role at Fastly. Edge Compute Engineers build Compute@Edge — Fastly's WebAssembly-powered edge computing platform that enables developers to run custom code at the edge of the internet. Unlike traditional CDN edge computing (which uses JavaScript V8), Compute@Edge uses WebAssembly for near-native performance with sub-millisecond cold start times.
Fastly (NYSE: FSLY, ~$4B market cap) is headquartered in San Francisco. Compute@Edge enables use cases like edge authentication, API gateways, personalization, A/B testing, and full edge applications — all running within milliseconds of end users. The platform supports Rust, JavaScript, Go, and other languages compiled to Wasm.
The role requires expertise in runtime engineering, WebAssembly, systems programming, and distributed systems — a rare combination at the frontier of edge computing technology.
