📋 Description

• Own and evolve our edge and cloud infrastructure across Cloudflare, Google Cloud, and Vercel. • Scale and operate our data layer including Spanner, ClickHouse, and Postgres. • Ensure we are optimizing for performance when serving LLM inference as traffic rapidly grows. • Partner with engineering leadership on capacity, reliability, and cost across the routing layer, with ownership of the systems carrying production traffic. • Set the bar and playbook for how we run infrastructure and operations as the team grows — tooling, observability, on-call, and the patterns other engineers build against.

🎯 Requirements

• 5+ years building and operating production infrastructure at companies where uptime, latency, and cost matter. • Proven experience with cloud platforms (GCP, AWS, Azure) and edge-first serverless platforms (e.g. Cloudflare Workers) • Deep expertise in operating large scale databases (e.g Postgres, Spanner, etc). • A full-stack TypeScript shop won't faze you; you can move across the stack when the platform needs it. • High agency and a bias toward action. You don't wait for tickets — you see the bottleneck and fix it. • AI-forward in your workflow. You use coding agents, MCPs, and LLMs heavily and have opinions about what works. • Pragmatic about tradeoffs between speed and simplicity.
