Software Engineer, Billing

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.

You will work across the billing stack — usage metering pipelines, subscription and entitlement systems, payment integrations, and the ledger layer — to make billing accurate, scalable, and transparent. This is a deeply technical IC role. It is not a finance ops role, and it is not a backend generalist role wearing a billing hat.

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.
