About the role
Every token that flows through OpenRouter is a financial event. Billions of requests run across hundreds of models and dozens of providers, and each request carries its own cost, price, discount and contract terms. Behind the inference engine sits a money engine: metering, pricing, invoicing, credits, payments, payouts and the ledger that ties it all together.

- Hands-on experience with Stripe (or similar processors) and a billing/invoicing platform, including contract, subscription and usage-based models
- Strong TypeScript and SQL. Comfortable with Postgres and analytical stores (ClickHouse or similar) at high event volume
