Staff+ Software Engineer, Billing Platform

<div class="content-intro"><h2><strong>About Anthropic</strong></h2> <p>Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.</p></div><h2 class="heading"><strong>About the role</strong></h2> <p>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. We build and operate the infrastructure that turns product usage into revenue across everything Anthropic ships: <a class="text-accent-secondary-100 underline" href="http://Claude.ai" target="_blank">Claude.ai</a>, the Developer Platform, Claude Code, and whatever comes next. The faster we can price it, charge for it, and account for it correctly, the faster Anthropic can fund the mission.</p> <p>We’re looking for a software engineer to join Billing. Depending on where you land, you might be building the integration contracts product teams plug into so they can launch a paid SKU without becoming billing experts, automating the quote-to-cash lifecycle so enterprise deals don’t bottleneck on manual ops, or building the reconciliation and data foundations that keep every revenue number trustworthy at audit time. This is production-critical infrastructure where correctness is non-negotiable — a rounding error here is a revenue discrepancy somewhere else — and you’ll work closely with Finance, Product, Sales, and Accounting to build systems that scale with the business.</p> <h2 class="heading"><strong>What you’ll do</strong></h2> <ul> <li> <p>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.</p> </li> <li> <p>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.</p> </li> <li> <p>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.</p> </li> <li> <p>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.</p> </li> <li> <p>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.</p> </li> <li> <p>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.</p> </li> <li> <p>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.</p> </li> <li> <p>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.</p> </li> </ul> <h2 class="heading"><strong>You may be a good fit if you</strong></h2> <ul> <li> <p>Have 8+ years building backend or platform systems in production, 3+ years leading large scale, complex projects or teams as an engineer or tech lead</p> </li> <li> <p>Have a track record of shipping in fast-moving environments where the requirements shift under you and you still land something correct and maintainable.</p> </li> <li> <p>Care about correctness and data integrity as first-class design concerns, not afterthoughts — and know how to build systems that are easy to reason about when money is on the line.</p> </li> <li> <p>Enjoy cross-functional work. Billing sits between Product, Finance, Sales, and Legal, and a lot of the job is translating between those worlds.</p> </li> </ul> <h2 class="heading"><strong>Strong candidates may also have</strong></h2> <ul> <li> <p>Built billing, payments, subscription, or fintech systems before — and know firsthand how a small pricing change ripples through the whole stack.</p> </li> <li> <p>Direct experience integrating or extending third-party billing and payment platforms, and opinions on where they fall short.</p> </li> <li> <p>Worked on revenue reconciliation, financial reporting pipelines, or systems that had to survive an audit.</p> </li> <li> <p>Experience with enterprise commerce — CPQ, quote-to-cash, contract management, or the operational side of B2B billing.</p> </li> <li> <p>Owned payments optimization in a self-serve or PLG environment — authorization rates, payment cost, fraud, chargebacks — and know what it takes to move those numbers without breaking the good customers.</p> </li> </ul><div class="content-pay-transparency"><div class="pay-input"><div class="description"><p>The annual compensation range for this role is listed below. </p>
