Job description

Our mission is to automate coding. The first step in our journey is to build the best tool for professional programmers, using a combination of inventive research, design, and engineering. Our organization is very flat, and our team is small and talent dense. We particularly like people who are truth-seeking, passionate, and creative. We enjoy spirited debate, crazy ideas, and shipping code.

About the role

We're hiring a Software Engineer, Billing to evolve the systems that power how Cursor charges and reconciles revenue across millions of developers and enterprise teams.

What you'll do

• Implement usage and billing systems changes end-to-end, from updates in the UI and raw usage events at the edge to invoiced amounts in Stripe, including the metering pipeline, aggregation logic, entitlement enforcement, and ledger.
• Evolve our ledger system that serves as the source of truth for customer balances, credits, overages, and adjustments - with the correctness guarantees that financial systems require.
• Integrate deeply with Stripe including subscriptions, usage records, invoices, webhooks, and edge cases like mid-cycle plan changes, prorations, and failed payment recovery.
• Build billing APIs and internal tooling that product, finance, and customer success teams depend on to query customer state, issue credits, and investigate billing anomalies.
• Improve observability across the billing pipeline - metering lag, reconciliation discrepancies, invoice accuracy - so the team can quickly detect and debug billing regressions.
• Partner with product, infrastructure, and finance teams to ship new pricing models with confidence and minimal operational risk.
• You will own usage limits across the product family, payments (stripe + daily jobs), grants promotions, ledger, and internal data insights. You will be a technical authority on billing correctness and scale.
• You will not own tax compliance, or general finance infrastructure unless it intersects directly with the billing system.
• You will not be a backend generalist who contributes to billing occasionally. This is the core of your scope.
• Revenue accuracy is part of the job, but the goal is to build systems with enough correctness and observability that billing is boring - not to manually reconcile every edge case.
