Senior iOS Engineer - Legacy Platform Modernization (Remote)

About the Role

We're hiring a Senior iOS Engineer (remote) to join our experienced iOS team focused on modernizing a legacy platform. This role is perfect for those who thrive in a pragmatic, product-led environment where delivering valuable features is as important as technical quality.

What You'll Do

• Help accelerate the delivery of a new initiative within an established organization.
• Work confidently across both modern and legacy iOS systems.
• Maintain, refactor, and incrementally modernize a UIKit + RxSwift codebase.
• Build new features using SwiftUI and modern Swift concurrency.
• Collaborate closely with engineers, product managers, and non-technical stakeholders.
• Communicate clearly and pragmatically at different levels of the organization.
• Take a quality-led approach to development, testing, and performance.

Requirements

• Strong, recent experience with native iOS application development in commercial, production environments.
• Experience maintaining and refactoring legacy UIKit + RxSwift systems.
• Proficiency in SwiftUI for modern UI development.
• Knowledge of modern Swift concurrency (Combine and async/await) alongside RxSwift.
• Familiarity with multiple architectural patterns: MVVM, MVI, and legacy patterns such as MVP.
• Experience with quality-led development (unit tests, UI tests, snapshot testing).
• Familiarity with CI/CD tooling and practices (e.g., CircleCI).
• Ability to diagnose and improve performance issues in mobile applications.

Nice to Have

• Deep experience with RxSwift / RxCocoa and reactive programming.
• Experience with unidirectional data flow patterns.
• Experience migrating legacy iOS codebases to modern Swift paradigms.
• Familiarity with video player SDKs (e.g., Brightcove, Ooyala, or similar).

What We Offer

• €330 per day, fully remote (EU-based contractors welcome).
• B2B engagement with on-time, reliable payments.
• Opportunity to work on real product initiatives, not greenfield demos.
• Exposure to both modern iOS practices and large-scale legacy systems.
• A pragmatic, product-focused engineering culture.
• Clear scope and meaningful impact over a 6-month delivery window.

This Senior iOS Engineer remote role is not just another greenfield rebuild fantasy; it’s a well-scoped contract for engineers who enjoy solving real problems, modernizing systems sensibly, and shipping features that matter for a globally recognized tech company.
