Senior React Native Engineer



Job description

Overview

Join to apply for the Senior React Native Engineer role at The Mobile-First Company.

About The Mobile-First Company: The company builds 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 dollars from Lightspeed, EMBLEM, and 30+ top operators.

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

Create solid foundations for our Mobile technology and deliver exceptional mobile applications.

Be critical in defining what Mobile means in the Mobile-First company.

What you'll do

  • Evolve our mobile capabilities and push the limits of what can be done
  • Work closely with designers, backend engineers, and business stakeholders
  • Define, build, and improve the tools and architecture behind our mobile app
  • Ship high-quality apps fast, while always improving UX and performance
  • Monitor usage and performance to identify what's missing or broken
  • Create internal tools, reusable components, and ways to ship faster

Mobile engineering

  • You've built and shipped mobile apps using React Native
  • You're comfortable with both iOS and Android
  • You've already worked on a product with a large user base
  • You know how mobile talks to the backend and how to debug it
  • Product and design mindset; you care about UX and clear UI
  • You think in terms of users, not features
  • You've built polished components with strong attention to detail
  • You know iOS and Android don't behave the same and plan accordingly
  • Performance and data: you know how to build scalable and maintainable code
  • You care about what to measure and how it impacts business and users; you 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 and help shape what's next
  • 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 mobile-first companies
  • You've built or contributed to apps with more than 1 million downloads
  • You're excellent at React Native
  • You have 4+ years of experience in mobile
  • 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
