Senior React Native Engineer 🇫🇷

About The Mobile-First Company

Most tools for small businesses weren’t built for real operators.
They were built for employees in offices, not people running a business from their phone.

We’re changing that.

We build mobile-first business software that feels like a consumer app, runs on AI, and spreads like a creator brand.

Our first product, Allô, gives you a second number on your phone, answers missed calls with AI, transcribes everything, and syncs it to your CRM.

Over 20,000 businesses use it every day.
Next up: expenses, invoicing, and more.

We’ve raised 5 million euros from Lightspeed, EMBLEM, and 30+ top operators.
Our team is based in Paris, Buenos Aires, and soon Miami.

Create solid foundations for our Mobile technology and deliver exceptional mobile applications. Be critical in defining what “Mobile” means in the Mobile-First company.

What will you do:

You’ll be our second mobile engineer. You’ll work side by side with Pablo (Founding Mobile Engineer) to build the foundations, the present, and the future of mobile here.
