Job Description

letgo is a revolution in marketplaces: it's mobile, easy to use and local. Our goal is to make selling and buying from people nearby a breeze! We’re looking for Senior Frontend Developer to join our dynamic product team!

We are a data-driven, agile team. Developers have the freedom to come up with new feature ideas and work closely with product managers & user experience designers to make an impact on the millions of users in letgo community. We ship often, get immediate user feedback and use experimentation to make decisions

We are very open to the use of new technologies. In our stack we have php, mysql, gearman, mongodb, orientedb, elasticsearch, redis, docker, javascript, node.js, and python among others, but we welcome the use of new tools/languages that help us improve.
