Software Engineer – Security & Infrastructure 🇦🇷

Most tools for small businesses weren't built for real operators. We build mobile-first business software that feels like a consumer app, runs on AI, and spreads like a creator brand. Our first product, Allo, 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. We've raised +15 million dollars from Base10, Lightspeed, EMBLEM, and 30+ top operators. Our team is based in Paris, Buenos Aires, Miami.
