Alongside Yelda’s CTO Marie, based in Paris, you will develop the backoffice of our management tools for voice bots automation in Node.js, including: defining architecture (database, hosting, deployment workflow), connecting to various APIs, setting up NLP tools (Natural Language Processing), developing our own secure APIs and obviously writing documentation and unit tests.


You will work hand in hand with our 2 fullstack developers Naomi and Balavishnu, and you may also need to write some custom modules depending on our customers’ needs.


Our next challenges will concern NLP (improve and monitor user messages understanding quality, implementation of RASA, ...), conversation logic improvement, back office monitoring and performance, and eventually Machine Learning, in order to improve the performance of our virtual assistants.
