• Keep high i18n coding standards, conduct code reviews, and mentor junior engineers on global-readiness best practices.

• Partner with UX Designers to ensure global design requirements are met early in the product lifecycle.

• Participate in our on-call rotation, available at all times while on-call to help respond to and triage any issues that arise.

• Proficiency in TypeScript, JavaScript, and hands-on experience building applications or libraries using React (or similar frameworks).

• Deep understanding of Unicode standards, CLDR (Common Locale Data Repository), ICU formatting, and BCP 47 locale codes.

• Hands-on experience with i18n libraries (e.g., i18next, react-intl, formatjs) and Translation Management Systems (TMS) like Phrase, Smartling, or Transifex.

• Strong knowledge of frontend localization challenges, including RTL layout rendering, CSS logical properties, and font fallback strategies.

• Experience integrating localization workflows into CI/CD pipelines (e.g., GitHub Actions, Jenkins) and working with serialization formats (JSON, XLIFF, PO, YAML).
