What We’re Looking For

We’re looking for a Lead iOS Software Engineer who is a world-class hands-on builder. You’ll set the bar for engineering excellence, lead by example through code reviews and architecture design, and inspire a growing mobile team to deliver elegant, reliable, and beautiful experiences that define what financial products should feel like.

This is a high-impact role on our Core Product Team, where you’ll help build and scale the ARQ experience - from our flagship app to new initiatives such as Premium, Credit, and other innovative financial products in the pipeline.

What You’ll Be Doing

  • Be the hands-on technical expert for all things iOS - writing world-class code, performing code reviews, and ensuring technical excellence across the app.
  • Collaborate with Product and Design to craft pixel-perfect user experiences with exceptional attention to detail, performance, and reliability.
  • Architect, build, and maintain scalable mobile features that are secure, fast, and delightful to use.
  • Review code, share insights, and elevate the quality of engineering across the app.
  • Drive the evolution of our mobile architecture to support a multi-product environment (Premium, Credit, and more).
  • Collaborate closely with cross-functional teams to ship quickly while maintaining uncompromising quality.
  • Own the full lifecycle of your features - from design and implementation to testing and deployment.

What You’ll Need

  • 6+ years of professional experience in iOS development, ideally building complex, high-scale consumer products.
  • Proven expertise in Swift and Apple’s iOS ecosystem (UIKit, SwiftUI, Combine, etc.).
  • Strong understanding of design patterns, architecture (MVVM, Clean Architecture), and testing practices.
  • Deep passion for UI/UX craftsmanship - you care deeply about the small details that make products amazing.
  • Proven ability to deliver outstanding products end-to-end in fast-moving, high-growth environments.
  • Bonus: Experience in fintech, payments, or digital banking.

Why You’ll Love It Here

  • Competitive salary
  • Hybrid setup
  • Sign-on stock options, so you own part of what you build
  • Discretionary performance bonus
  • The latest tools and technology
  • A growing mobile team with a high bar for product quality
  • A world-class team that will challenge and grow your skills
  • The opportunity to help build the best fintech app in Latin America
