Software Engineer Intern

We’re the rebels of the translation world, on a mission to revolutionize how businesses connect with their global audiences. Think of us as matchmakers, pairing companies with the perfect words in every language.

We launched our first product—a lightning-fast A/B testing tool that’s already helping 20+ companies perfect their messaging! Now, we’re building on this vision and partnering with leading tech startups to create an even more ambitious product .

Current localization software—tools used to manage and display translations on websites, web apps, or mobile apps—are largely outdated, with many still using 2005 technology to solve 2024 challenges. We're designing a completely new approach to website translation, addressing every issue that existing software currently overlooks, so you get:

Founded in March 2024 by Aude Flecchia (CEO), Antoine Borrelly (CPTO), and Jehan Oré (COO) and already backed by VCs who believe in our mission, we’re not just another startup. We're a rocket ship that just left the launchpad! ​

We’re a mighty team of 5 people (soon to include YOU ), up to 8, including freelancers. And you’ll work closely with the 3 founders.

Aude graduated from HEC Paris & Yale Business School, is an ex-Bain consultant in NYC , and the queen of fundraising and sales.

Antoine studied at ISEP and UC Berkeley before working at Lydia as a Product Manager. He masters Product as well as Engineering—double hat, double responsibilities.

Jehan is also an engineer, a graduate of Centrale Lyon & Imperial College Business School, a serial entrepreneur (2+ startups before founding Gleef), and he looks like Anthony Bourbon, but shhh, don’t tell him that.
