Job description

The Role

As the iOS Mobile Lead Engineer, you’ll take ownership of the iOS applications end to end — from architecture and performance to team leadership and delivery. You’ll work closely with Product, Design, and Engineering leadership to build scalable, reliable, and elegant mobile solutions used globally.

The apps are built primarily with Swift and SwiftUI, with some legacy Objective-C, and they are actively modernising toward best-in-class iOS patterns and tooling.

What You’ll Do

• Own and evolve the iOS platform, ensuring high performance, stability, and scalability
• Architect and deliver new end-to-end features, from backend integration to refined UI
• Lead, mentor, and develop a team of iOS engineers
• Partner with Product and Engineering Managers on planning, estimation, and roadmap delivery
• Support multi-region deployments and localisation as the platform expands globally
• Drive modernisation initiatives, migrating toward SwiftUI, Combine, and Swift Concurrency
• Collaborate with Android and Web leads to align mobile architecture and best practices
• Monitor app health including performance, crash rates, and battery usage
• Manage App Store releases, certificates, provisioning, and compliance with Apple guidelines

What We’re Looking For

Leadership & Strategy

• Proven experience leading iOS teams in a hands-on technical leadership role
• Strong collaboration skills with Product and Design partners
• Ability to balance long-term architectural thinking with delivery

Technical Expertise

• Deep expertise in iOS development using Swift and SwiftUI
• Experience designing modular, scalable, and testable mobile architectures
• Strong understanding of performance optimisation, state management, and modern concurrency
• Experience with CI/CD pipelines (Fastlane, CircleCI, or similar)

Quality & Problem Solving

• High standards for code quality, testing, and maintainability
• Experience integrating APIs (REST / GraphQL) and working with real-time data
• Strong analytical skills and pragmatic problem-solving ability

Nice to Have

• Exposure to Kotlin Multiplatform (KMP)
• In-depth knowledge of App Store Connect, localisation, and Apple review processes
