Backend Engineer

Build the systems behind the product.

The fundamentals every backend engineer reaches for daily: a programming foundation in Python and TypeScript, HTTP and APIs, databases and indexes, the unix shell, bash discipline, containers, CI/CD pipelines, system design at scale, and the SRE practices that keep services alive in production.
