This role emphasizes correctness and scalability in the revenue infrastructure, with opportunities to influence third-party billing integrations and build robust reconciliation

Qualifications

• 8+ years building backend or platform systems in production.
• 3+ years leading large scale projects or teams as an engineer or tech lead.
• Experience with enterprise commerce and billing platforms.

Responsibilities

• Design and ship billing capabilities end to end.
• Own the payments stack, including authorization retries and dispute controls.
• Collaborate with Finance, Product, Sales, and Accounting to ensure GAAP-clean data.

Job description

• 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
• 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
• 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

Benefits

• Comprehensive health, dental, and vision insurance for you and your dependents
• Inclusive fertility benefits via Carrot Fertility
• 22 weeks of paid parental leave
• Flexible paid time off and absence policies
• Mental health support for you and your dependents
• Competitive salary and equity packages
• Optional equity donation matching at a 1:1 ratio, up to 25% of your equity grant
• Retirement plans with competitive matching
• Life and income protection plans
• $500/month flexible wellness and time saver stipend
• Commuter benefits
• Annual education stipend
• Home office stipends
• Relocation support for those moving for Anthropic
• Daily meals and snacks in the office
