Staff Software Engineer, Billing Platform

Anthropic Anthropic · AI Frontier · San Francisco, CA · Engineering & Design - Product

Software engineer for Anthropic's Billing Platform, responsible for building and operating the infrastructure that handles pricing, charging, and revenue accounting for all Anthropic products. This role focuses on production-critical financial systems where correctness and data integrity are paramount.

What you'd actually do

  1. Design and ship billing capabilities end to end — pricing primitives, payment flows, contract and entitlement models, revenue data pipelines — depending on the surface area you own.
  2. Build for correctness first. Billing data is financial data; you’ll develop the instincts for where idempotency, reconciliation, and audit trails matter and where they don’t.
  3. Own the interfaces. Whether it’s the billing API a product team integrates against or the revenue dataset Finance closes the books on, you’ll design contracts that hide the complexity and hold up under change.
  4. Make build-vs-buy calls. We lean heavily on third-party billing, payment, and tax platforms, and you’ll decide where to extend them and where to build our own primitives around them.
  5. Own the payments stack. Authorization rates and retry logic so a good card doesn’t silently decline, processing cost as a real number you drive down, automated dispute response, and fraud controls that stop bad actors without blocking real customers.
