Software Engineer, Internationalisation Platform

The i18n Platform team owns all the ways we create, process and deliver internationalisation features for our users at Klaviyo.  As a Software Engineer on the team, you will be involved in how we manage translations, deliver new localisation features, handle multiple currencies, and improve our internationalisation processes.

You can look forward to being a part of a highly technical team with significant domain expertise. We oversee tools and services that are leveraged across the organization from the frontend UI to backend data.  The team also owns and orchestrates several services to manage the pipeline of translations with our localisation team.

As we look toward the next 6-12 months, we aim to focus on delivering LLM workflows to improve our translation capabilities, increase the availability of our Smart Translations product, and develop new features for handling different currencies in multiple regions.
