Staff Software Engineer (Billing Platform)

• 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

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 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 Enjoy cross-functional work.

Billing sits between Product, Finance, Sales, and Legal, and a lot of the job is translating between those worlds Have a track record of shipping in fast‑moving environments where the requirements shift under you and you still land something correct and maintainable Worked on revenue reconciliation, financial reporting pipelines, or systems that had to survive an audit Direct experience integrating or extending third‑party billing and payment platforms, and opinions on where they fall short We encourage you to apply even if you do not believe you meet every single qualification.

Not all strong candidates will meet every single qualification as listed.

Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you’re interested in this work Experience with enterprise commerce — CPQ, quote‑to‑cash, contract management, or the operational side of B2B billing Built billing, payments, subscription, or fintech systems before — and know firsthand how a small pricing change ripples through the whole stack 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
