Software Engineer, Payments

The Payments Team is working to make AGI financially sustainable by enabling OpenAI to accept payments across our existing products (ChatGPT, ChatGPT for Teams, API) and supporting future commercial experiences. We own the user-facing payments experience, direct integrations with payment service providers, and other supporting infrastructure that powers checkout and payment flows.

Payments works closely with teams across Finance, Legal, Growth, Product, external vendors and more to ensure our payments infrastructure scales with the business and supports evolving commercial goals.

As a Software Engineer on the Payments Team, you will play a pivotal role in shaping the infrastructure that powers OpenAI's financial systems. You'll design and build core payments systems, partner with cross-functional teams to deliver scalable solutions, and ensure that our financial systems support rapid product iteration and global reach.

We're looking for people who are pragmatic, collaborative, and energized by the opportunity to build systems that are foundational to OpenAI's long-term mission and sustainability.

This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.
