The Quality Analytics Team at Lilt

Lilt is a high-performance, large-scale language translation system powered by interactive machine translation. We have a large and diverse translation workforce that is distributed worldwide, whose interactions with the system form a fascinating large-scale dataset for researching translators' behavior.

Lilt’s Quality Analytics Team is part of the larger Production team which is a global workforce operating across four continents. We are passionate about localization and making information accessible to all. The team consists of project management, program management, quality, and talent management, working with some of the world’s largest organizations. Working on Lilt’s Quality Analytics Team you will have access to leading tools, collaborative teammates, and opportunities to make a real impact.


What you’ll do

You will be playing a key role in building the capabilities in language translation quality measurement and drive improvements in the quality deliverables. You will be building quality measurement tools to evaluate and monitor the quality of the translation of our human translators which would be used to make decisions on optimizing the document workflow. To develop these tools you will also be evaluating the use of various state-of-the-art tools including the latest developments in large language models. You will also be developing tools to assess the quality of the linguists that is most appropriate for a particular project. Additionally you will build predictive models to estimate the quality of the translation and enable optimal placement of the projects to maximize quality.

This position can be based out of any of our hubs and will be expected to work in the office in a hybrid capacity (where and when applicable).


Key Responsibilities

  • Experience in quantitative user experience research methods, such as experiment design and A/B testing

  • Experience with software development to deploy ML models in user-apps


Our Story

Our founders, Spence and John met at Google working on Google Translate.  As researchers at Stanford and Berkeley, they both worked on language technology to make information accessible to everyone. They were amazed to learn that Google Translate wasn’t used for enterprise products and services inside the company and left to start a new company to address this need – Lilt. 

At its core, Lilt has always been a machine learning company since its incorporation on March 6, 2015. At the time, machine translation didn’t meet the quality standard for enterprise translations, so Lilt assembled a cutting-edge research team tasked with closing that gap. While meeting customer demand for translation services, Lilt has prioritized investments in Large Language Models, believing that this foundation was imperative to the future of enterprise translation.
