This is a role for an experienced mobile engineer who thrives on complexity, cares deeply about clean architecture, and wants to build real, scalable fintech products used by tens and hundreds of thousands of users.

⚠️ Please DO NOT apply if you DO NOT have proven experience building complex fintech OR enterprise-grade iOS applications.

🚀 Project

Trigger Neobank Engine is a powerful platform that allows banks, fintechs, and telcos to launch complete digital banking products — from retail to SME and corporate — 5x faster and 10x more cost-efficient.

As an iOS Developer, you will:

• Continuously refine architecture, improve performance, and maintain a clean, healthy codebase
• Contribute to internal tools, libraries, and frameworks used across multiple projects
   

🛠 Required Skills & Experience

• 10+ years of hands-on iOS development (Swift; Objective-C is a plus)
• Deep understanding of iOS SDK, architectural patterns (MVVM, VIPER, Clean Architecture), and UIKit/SwiftUI
• Strong grasp of SOLID, dependency injection, and scalable modular architecture
• Proficiency with multithreading (GCD, async/await, Combine, or RxSwift)
• Experience integrating and orchestrating REST APIs, handling edge cases in network-driven apps
• Strong skills in UI development, dynamic components, animations, accessibility, and Auto Layout
• Experience with server-driven UI or hybrid rendering approaches — strong advantage
• Experience working on fintech or enterprise apps (banks, wallets, B2B SaaS) — strong advantage
• Confident with Git/Git Flow, CI/CD, and modern tooling

📚 Engineering Mindset & Expectations

• Understanding of modular, reusable codebases
• Ability to navigate and design large-scale mobile architectures
• Obsession with clean, maintainable, testable code
• Strong eye for UX quality and interaction details
• Willingness to challenge assumptions and own end results
• Eagerness to work closely with backend/product to build a true platform, not just an app

👤 Personal Qualities
