Staff Software Engineer, Billing PlatformActive$320K

The opportunity

Anthropic exists to ensure the world safely navigates the transition through transformative AI. That work is funded by commercial revenue — and every dollar of it runs through Billing Platform.

What you'll do

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Drive down the manual work. Enterprise contract amendments, pricing config: changes, billing support escalations — a lot of it is still human-in-the-loop, and closing that gap is a direct line to scale.

What they're looking for

  • Operate what you ship. You’ll own SLOs on customer-facing flows, instrument: the revenue pipeline so discrepancies surface before month-end close, and be on the hook when it pages.
  • Partner across the company. Growth wants promotional mechanics, Sales wants: quote flexibility, Finance wants GAAP-clean data, product teams want it yesterday — you’ll help thread that needle.
