Why You Should Join the Internationalisation Platform Team
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.
Why you should join
We foster a culture of psychological safety, collaboration, and work/life balance through flexible hours and structured on-call rotations.
We practice a “you make it, you support it” attitude to our products and provide on-call support in case of incidents. We offer compensation for on-call rotations and expect to maintain a very low number of incidents requiring call-out. New engineers are onboarded to the on-call rotation gradually, typically joining the active rotation after their first 6 months and thorough training.
We are committed to your growth. You will be paired with a dedicated mentor and given time for focused skill development, including opportunities to attend relevant industry conferences and a growing suite of learning & development opportunities.
We enjoy a high degree of autonomy to generate innovative solutions across the entire system, learning directly from customers and suggesting cool new approaches.
Free lunch at our Aldgate office three times a week
Highly competitive salary, equity package, and comprehensive health benefits.
How You Will Make a Difference
You will collaborate closely with the team to build the next generation of i18n features for our customers and fellow engineers.
You will be responsible for implementing new functionality into complex systems.
You will work closely with engineers from other teams across Klaviyo to bring internationalisation processes and features to their code.
You will be an active participant in all team processes including standups, backlog refinement, retrospectives, on call, and more.
You will help interview new engineering team members as we continue to grow our organization.
You will own and deliver features end-to-end, learning to scope and execute small-to-medium-sized projects under the guidance of your mentor.
