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 DolarApp 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

• Sign‑on stock options, so you own part of what you build

• Discretionary performance bonus (stock options)

• Paid annual leave

• State‑of‑the‑art technology and tools

• A world‑class team that will challenge and grow your skills

• The opportunity to shape the financial system of the future
