• Build tools that enable linguists and localization teams to review and improve translations.

• Develop developer tooling that simplifies localization and internationalization workflows.

• Build and maintain internationalization libraries used across OpenAI products:

• Design systems that correctly handle numbers, currencies, dates, and pluralization across locales.

• Improve support for multilingual interfaces and right-to-left languages.

• Partner with product teams to improve the international readiness of new features.

You might thrive in this role if you

• Have strong software engineering experience building backend or full-stack systems.
