## Job description

## 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 https://www.withallo.com/, 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.

## MISSION

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

## WHAT WILL YOU DO

- Work closely with our CTO and engineering team to design and evolve the core backend and platform architecture that powers all our applications.
- Mentor and support other engineers.
- Lead complex technical initiatives across backend systems, data infrastructure, CI/CD pipelines, and developer tooling.
- Define and implement scalable foundations that allow the team to ship faster and operate reliably as we grow.

## WHAT YOU’LL BE WORKING ON

- Designing and evolving the backend architecture that powers our products and internal platform.
- Building scalable and reliable services.
- Improving infrastructure, observability, reliability, and deployment workflows across the engineering stack.
- Working directly with cloud services (e.g., AWS, Supabase, Cloudflare).
- Leading technical decisions and helping the team scale operationally.

## WHAT WE’RE LOOKING FOR

## BACKEND ENGINEERING

- Strong expertise in backend development with languages like Kotlin, Java, Go, Python, or similar.
- Proven experience building and operating scalable backend systems in production.
- Deep understanding of distributed systems, reliability, and performance optimization.
- Experience integrating AI models or AI-powered workflows into real product systems is a strong plus.

## SYSTEMS ARCHITECTURE

- Strong experience designing scalable architectures and making high-impact technical decisions.
- Ability to design systems that remain reliable, observable, and maintainable as the company scales.

## PLATFORM & INFRASTRUCTURE

- Experience designing and improving developer platforms, CI/CD pipelines, or internal engineering tooling.
- Strong understanding of cloud infrastructure and production environments.
- Experience with monitoring and observability tools such as New Relic, Datadog or similar.

## HOW YOU THINK

- You care about why we build things, not just how.
- You ask smart questions, challenge ideas when needed, and help shape what’s next.
- You think in terms of user value and business impact.

## HOW YOU WORK

- You communicate clearly, give feedback with no ego, and help others grow.
- You move fast, take ownership, and thrive in ambiguity.
- You're comfortable working in English and in a small team with big goals.

## WHAT MATTERS TO US

- You’ve worked in product companies.
- 7+ years of experience building and operating large-scale backend systems.
- Experience owning or influencing architecture decisions across teams.
- You’re proactive, autonomous, and comfortable operating in early-stage startup environments.
- You can communicate in English, since that’s our official language. Most of the team also speaks Spanish and French.

## WHAT WE OFFER

- Competitive salary (in USD or local equivalent)
- Equity package
- 10-day team retreats abroad every quarter
- Trips to our Hubs (Pairs/Miami/BA) for onboarding and more
