Mid

Distributed systems engineer scaling Replit's cloud infrastructure for AI-built apps

Interview for Replit's Compute Platform team, building the cloud infrastructure (Golang/Rust) that lets Replit Agent deploy and run millions of user-built apps reliably and cost-efficiently. Expect deep distributed-systems and Linux-internals questions, plus reliability and cost-optimization scenarios, given oncall rotation is required.
