Senior/Middle iOS Developer (Complex Fintech and B2B SaaS Platform) to $3500

We’re looking for a Senior/Middle iOS Developer to join our team and contribute to the development of Trigger Neobank Engine — our flagship platform for building fully digital banks.

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:

• Work on highly configurable mobile banking applications
• Build reusable dynamic UI and component-based architecture
• Create native mobile components that integrate with our no-code Interface Engine
• Solve real-world fintech challenges like dynamic rendering, multilevel configuration layers, and complex flows
• Own the mobile delivery end-to-end and collaborate closely with UI/UX, backend, product, and implementation teams

🎯 Key Responsibilities

• Design and implement a customizable, modular, scalable, and testable Mobile Interface Engine for iOS
• Build elegant, functional, and reusable UI components following best UX and architecture practices
• Ensure performance, stability, and security across all iOS devices
• Work closely with designers and product managers to deliver dynamic components driven by backend configurations
• Participate in code reviews and provide strong technical leadership
• 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

• 5+ 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

• Proactive and responsible — this is non-negotiable
• Strong communication and problem-solving skills
• Ability to work independently in a fully remote environment
• Comfortable interacting directly with stakeholders and product owners
• Open-minded, feedback-driven, and growth-oriented
