Senior Back-end Developer

Yubo is hiring!

About

Yubo is a live social discovery app launched in 2015, with the ambition to create a space where Gen Z can belong, feel safe and make friends.
With more than 70 million users worldwide across 140 countries, we celebrate the true essence of being young, and make it easy to connect with others wherever you are.

We are a French Tech company, part of the Next120, and our mission is to inspire and enable a new generation to find out about the world and themselves. Yubo’s business model is different from other social networks: in-app purchases and subscriptions. Yubo’s growth relies on paid UA, not virality.

Our objective is to become the safest social app in the world.
Indeed, as leading platform for young people to socialize online, we have a special responsibility towards our community to building a safe digital space, and we take it very seriously. Safety is at the core of our DNA, and we have developed and implemented a wide range of safeguards in the app. We also work closely with the broader technology industry, NGOs and charities to create industry-leading child protection standards.

We really have a proactive approach to protect, support and educate.
