Senior Frontend 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**.
