Staff Backend Engineer, Financial Engineering

Applied AI Engineering - San Francisco

About the Team

Financial Engineering (FinEng) builds the financial systems behind ChatGPT. These products serve people, developers, and businesses around the world. We make them easy to buy, use, and pay for.

Our systems support everything from individual subscriptions to usage-based billing and complex enterprise agreements.

We also build the foundations for how products are packaged, accessed, and used: product catalogs, SKUs and bundles, workspaces, entitlements, and usage metering. These systems connect what customers purchase to the capabilities they can access and the usage they can manage.

That reach creates challenging engineering problems. We build services and data pipelines that handle large volumes of usage and transactions, keep payments, product access, and financial records consistent across systems, and adapt as products and pricing change. The same foundations must support a simple checkout and the detailed spending controls a large business needs.

• Keep charges and product access correct when requests are retried, updates arrive late, or another service fails.
• Build metering systemsation, and records that are easy to trace and verify.
• Create reusable building blocks that let product teams launch new offerings, pricing, and payment options without rebuilding the foundations each time.
• Make complex financial workflows simple for customers and internal teams, using customer feedback and experiments to improve the experience.
• Scale and evolve live systems while protecting customer accessance, and security.
• Own problems from early design through launch and operation, working with product, design, finance, and other engineering teams to make and test important technical decisions.

Nice to Have
