About the role

About the Team

OpenAI’s mission is to ensure that artificial general intelligence benefits all of humanity. A majority of our users interact with our products in languages other than English, and our products must work seamlessly across languages, regions, and cultures.

The Internationalization team builds the infrastructure that enables OpenAI products to ship globally by default. We develop the systems that power localization, international product launches, and high-quality global user experiences across all OpenAI products.

About the Role

As a Senior Software Engineer on the Internationalization team, you will build the systems that power localization and international product launches at OpenAI. You’ll work on the platform that manages product content, translation workflows, and localization infrastructure across our products.

This role sits at the intersection of AI systems, developer platforms, and product infrastructure.

In this role, you will

  • Build and scale OpenAI’s localization, content, and experimentation platform used across OpenAI product teams, including open-source components:
  • Develop AI-powered translation pipelines combined with human-in-the-loop review workflows.
  • Design systems that reliably deliver localized product content across web and mobile apps.
  • 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.
  • Have familiarity with Java, React, MySQL, and cloud infrastructure patterns such as object storage, containerized services, and Kubernetes.
  • Enjoy building platforms and internal tools used by many teams.
  • Have experience with or appreciation for open-source software and developer tooling.
  • Are interested in combining AI systems with human workflows.
  • Care about product quality and global user experience.
  • Appreciate cultural and linguistic differences across regions; multilingual proficiency is a plus.
