The Internationalisation team builds the platform that helps Stripe products work naturally across languages and markets. We create and operate the infrastructure that enables Stripe teams to localize product interfaces, services, and written communications while delivering consistent, high-quality experiences to users around the world.
What it asks for · 5
- Strong coding skills in any programming language (we understand new languages can be learned on the job so our interview process is language agnostic)
- Experience developing reliable infrastructure, platform, or backend-service solutions.
- Strong product judgment and a commitment to building high-quality user and developer experiences.
- Ability to own ambiguous work end to end and make progress through research, experimentation, and iteration.
- Strong written and verbal communication skills, with the ability to work effectively in a collaborative, cross-functional environment.
Also a plus
- Experience building or operating production LLM or machine-learning systems.
- Experience evaluating LLM output or combining automated systems with expert human review.

- Build and maintain integrations with translation-management systems, LLM services and external localization providers.
- Evolve Stripe’s existing production LLM capabilities to improve translation quality, market relevance, turnaround time, and operational efficiency.
- Develop automated quality checks and human-evaluation workflows that combine LLM-driven automation with expert linguistic judgment.
