Staff Software Engineer, Billing Platform

About the role

Anthropic is building a Billing Platform that turns product usage into revenue for its AI services. As a Staff Software Engineer you will own critical parts of this infrastructure, ensuring pricing, payment, and revenue data are accurate and scalable.

Key responsibilities

• Design and ship end‑to‑end billing capabilities, including pricing primitives, payment flows, contract models and revenue data pipelines.
• Prioritize correctness and build robust idempotency, reconciliation and audit mechanisms for financial data.
• Define and maintain billing APIs and revenue datasets that hide complexity from product teams and finance.
• Evaluate build‑vs‑buy decisions for third‑party billing, payment and tax services, extending or replacing them as needed.
• Own the payments stack, handling authorization rates, retry logic, dispute automation, cost optimisation and fraud controls.
• Reduce manual processes such as contract amendments, pricing changes and billing support escalations.
• Operate the services you ship, setting SLOs, instrumenting pipelines for early discrepancy detection and responding to incidents.

Required profile

• Proven experience building production‑critical, revenue‑impacting infrastructure.
• Strong collaboration skills with Finance, Product, Sales and Accounting teams.
• Ability to make data‑driven decisions and balance engineering trade‑offs.
