Our Tech team

1. Technologies we use:

• We're mainly relying on three different languages:
  • Ruby in the backend (for APIs and crawlers).
  • Typescript in the frontend (for our React SPA).
  • Python (mainly used by our Data Science team).

• Everything is hosted on AWS and running on K8s, and we have created a robust CI system to develop and deploy our code quickly. We deploy directly from Slack!

2. We are organized by squads.

• One year and a half ago, we changed our internal organization by moving from a structure splitted by stack to something more features-oriented. We created cross-skill squads that are focused on specific parts of the tool to develop and maintain them more efficiently and quickly. Each of them is responsible for its roadmap, and everyone in the squad can participate in product discussions.

3. We value ownership and an entrepreneurial mindset.

What's in it for you?
