[GBL] Technical Lead Mobile (iOS & Android)

Job Description

Project – the aim you’ll have

Our client delivers personalized and seamless digital experiences to millions of members. Following a major re-platforming initiative, we are adopting a modern cloud-native architecture to accelerate mobile development across both iOS and Android platforms.

As Technical Lead Mobile, you will be responsible for shaping the mobile architecture, technical strategy, and engineering excellence across both native platforms. You will lead a cross-functional mobile engineering team, drive alignment between iOS and Android codebases, and ensure our apps deliver secure, high-performing, and scalable experiences that complement our cloud-native web ecosystem.

This is a hands-on technical leadership role – you will contribute code to critical features while mentoring engineers, defining standards, and making key architectural decisions that impact millions of users.

Position – how you’ll contribute

• Define and evolve the mobile architecture strategy for both iOS (Swift) and Android (Kotlin) platforms, ensuring scalability, performance, and maintainability
• Lead technical decision-making on cross-platform consistency, shared design patterns (MVVM, MVI, Clean Architecture), and platform-specific optimizations
• Design and develop critical native features in iOS (Swift, SwiftUI) and/or Android (Kotlin, Jetpack Compose), including secure authentication flows (Auth0, OAuth2) and cloud service integrations
• Mentor and upskill senior and mid-level mobile engineers through code reviews, design reviews, architecture discussions, and pair programming
• Establish and enforce mobile engineering standards: code quality, testing strategies (unit, UI, integration), security practices (Keychain, secure storage, certificate pinning), and CI/CD best practices
• Drive adoption of automated testing frameworks (XCTest, JUnit, Espresso, Compose UI tests) and mobile observability tools (Firebase Crashlytics, analytics platforms)
• Collaborate closely with Product, UX, Backend, and DevOps teams to align mobile technical roadmap with business priorities and ensure seamless API integrations
• Unblock complex technical challenges, conduct root cause analysis for production issues, and champion continuous improvement across mobile platforms

Qualifications

Expectations – the experience you need

• 5+ years of commercial mobile development experience with deep expertise in native iOS (Swift) and/or native Android (Kotlin)
• 2+ years in a technical leadership role (Tech Lead, Staff Engineer, or equivalent), with proven experience mentoring engineers and driving architectural decisions
• Strong command of modern mobile architecture patterns (MVVM, MVI, Clean Architecture) and ability to apply them pragmatically across platforms
• Hands-on experience integrating REST APIs, implementing secure authentication workflows (OAuth2, Auth0, JWT), and working with cloud-based backend services
• Proficiency with automated testing frameworks: unit tests (XCTest, JUnit), UI tests (Espresso, Compose UI tests, XCUITest), and CI/CD pipelines (GitHub Actions, Fastlane)
• Proven track record shipping production-grade mobile applications at scale, with focus on performance optimization, reliability, and user experience
• Strong problem-solving mindset, excellent communication skills, and ability to translate business requirements into scalable technical solutions
• Team-oriented leader who fosters a culture of engineering excellence, code quality, and knowledge sharing

Additional skills – the edge you have

• Experience with cross-platform technologies (Kotlin Multiplatform Mobile - KMM, shared business logic layers) and evaluating platform-specific vs. shared solution trade-offs
• Familiarity with mobile analytics and engagement platforms (Amplitude, Braze, Firebase) and push notification strategies
• Knowledge of cloud platforms (AWS, serverless architectures) and infrastructure-as-code tools (Terraform, Cloudflare) in mobile context
• Experience with WebViews, hybrid app architectures, and performance considerations for web-native integrations
• Understanding of mobile DevOps practices: feature flags, A/B testing frameworks, staged rollouts, and mobile-specific monitoring/alerting strategies
