Software Engineer, Platform

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.

Existing user of OpenRouter, or active side projects in AI products/infrastructure or developer tooling.

The base salary for this full-time position in the United States, spanning multiple internal levels depending on qualifications, ranges between $215,000 to $285,000 plus benefits & equity. Compensation for internationally based candidates will vary to reflect local market conditions.
