Senior Backend Engineer Job Opening In Santa Fe – Now Hiring The Mobile First Company


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, 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.

We’ve raised +$5 million from Lightspeed, EMBLEM, and 30+ top operators.

Our team is based in Paris, Buenos Aires, Miami.

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.

Working directly with Cloud services (e.g., AWS, Supabase, Cloudflare).

Creating tools, libraries, or components to enhance the efficiency of backend development processes.

What we’re looking for

Backend Engineering

Proficiency in backend development with expertise in languages like Kotlin, Java, Go, Python or similar.

Familiarity with database design, management, and optimization.

Track record of building and maintaining scalable and reliable backend systems.

Experience with AI is a strong plus, especially in applying models to real‑world product use cases and optimizing performance in production environments.

Systems Architecture

Expertise in designing scalable and maintainable backend architectures, understanding when to apply different architectural patterns.

Capable of monitoring the whole architecture using tools like New Relic or Datadog.

Performance and Data

Know how to build scalable and maintainable code.

Care about what to measure and how it impacts business and users.

Track behavior, usage, and performance, and improve based on it.

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.

4+ years of experience designing and building high‑performance systems used by millions.

You’re proactive, autonomous, and know how to fill the gaps.

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.

30‑day onboarding in Paris (we cover flights and housing).

Laptop and work setup of your choice.

Private health insurance (for US or LATAM hires).

A tight, ambitious team building something real — fast.

How to apply

Click the Apply button on this page to send your application.

No cover letter needed — just tell us who you are and why this role fits you.

Not the perfect match, but want to join us?

Diversity and Inclusion

Send a spontaneous application to ****** welcome people from all backgrounds.

If you’re part of an underrepresented group in tech, we especially want to hear from you.
