Yelda recrute !

À propos

Get your voice-ready virtual assistant in a minute. Yelda's platform works with your website, Google Assistant & Home, Amazon Alexa, Facebook Messenger, etc.


Yelda is a start-up founded by the entrepreneurs behind KRDS (8 offices worldwide / several successful rounds of fundraising) and CommitStrip (1M readers/month). Over the last 20 years most businesses have gone (nearly entirely) paperless. Now, we’re in a new era: the era of assistance and automation. Within three to five years, every company will need a stand-alone voice assistant connected to major support platforms (Alexa, Google Assistant...).

Our mission: provide every company in the world with a smart Voice Assistant via our platform Yelda.

In just a few months, Yelda has already earned the trust of its first customers including BNPP Bank, the nationwide FNAC retailer, and the French national railway operator SNCF. After completing our first seed fundraising, we are looking to build a solid team in Paris with expertise in web product development, artificial intelligence and business automation, composed of Yelda’s founders and ‘early employees’. Ready to join the adventure?

Descriptif du poste

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.

Your daily tasks:

  • Daily meeting with the other members of the project
  • Yelda project development in coordination with other team members.
  • Writing technical documentation and tests
