About the role

Software Engineer on the Platform team responsible for owning and scaling the systems that route and serve millions of LLM requests daily, across edge and cloud infrastructure, data stores, CI/CD, and platform tooling.

Responsibilities

  • 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.

Qualifications

  • 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; ability to 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.
