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, 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.
Next up: expenses, invoicing, and more.

We’ve raised +15 million dolars from Base10, Lightspeed, EMBLEM, and 30+ top operators.
Our team is based in Paris, Buenos Aires , Miami.

Drive the evolution of our backend technology, infrastructure, and AI capabilities to ensure high performance, scalability, and seamless integration for our mobile applications.

What will you do:

- Work side by side with our CTO to build the foundations, the present, and the future of our backend, and AI systems.

- Develop and enhance backend systems for both existing and new applications in conjunction with mobile engineers.

- Contribute to systems design, infrastructure planning, CI/CD processes, and data workflows.

What you’ll be working on

- Implementing and maintaining scalable and reliable backend systems using languages like Kotlin, Java, Go,



Python or similar.

- Designing and defining backend tools, databases, and the architecture of our apps.
