Staff Mobile Architect & Platform Lead

Airwallex; Singapore; On-site; SGD 210,000 - 280,000; Full time

Job summary

Airwallex is seeking a Staff Mobile Engineer for its Mobile Foundations team in Singapore. You will shape architecture across iOS and Android, driving shared libraries, tooling, and scalable platform capabilities.

You’ll lead cross‑team initiatives, raise the bar on quality, security, and observability, and own CI/CD pipelines. The role requires strong leadership, hands‑on coding, and a track record of delivering at scale.

Qualifications

• 8–10+ years of experience building native mobile applications on iOS or Android, including at least 3+ years operating at a Senior or Staff level.
• Deep expertise in one native mobile platform: Swift, SwiftUI, Combine, and async/await on iOS, or Kotlin, AndroidX, Jetpack, Coroutines, and Hilt on Android, with commercial knowledge of both platforms.
• A proven track record of leading cross-team technical initiatives and evolving mobile architectures, such as modularisation, design systems, networking, or offline support.
• Strong focus on code quality and reliability, including designing for testability and maintainability and writing high-quality automated tests.
• Experience owning and improving mobile CI/CD pipelines, including build optimisation, test stability, and release workflows using tools such as GitHub Actions or Bitrise.
• Experience driving mobile application security, performance, reliability, observability, or release engineering.
• Demonstrated ability to influence without authority, align engineers, product managers, and designers around technical direction, and make pragmatic trade-offs.
• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.

Responsibilities

• Define and evolve the shared mobile architecture across navigation, state management, networking, offline strategies, error handling, modularisation, and boundaries between platform foundations and product features.
• Own critical mobile platform capabilities, including design system components, analytics, feature flags, experimentation, authentication, payments, and observability, making them stable, well-documented, and easy for product teams to adopt.
• Improve mobile application security, reliability, performance, and observability through anti-tampering measures, certificate pinning, security best practices, crash reporting, logging, metrics, and tracing.
• Define and track platform-level measures such as crash-free sessions, ANRs, app start-up time, bundle size, and network performance, using data to guide priorities with product teams.
• Own and continuously improve mobile CI/CD pipelines and release workflows across iOS and Android, reducing build times, test flakiness, and friction in shipping new versions.
• Drive cross-squad technical initiatives from problem definition through rollout and adoption, aligning engineering, product, design, and platform stakeholders around technical direction and trade-offs.
• Raise the bar for mobile engineering through hands-on technical leadership, design reviews, mentoring, documentation, automation, best practices, hiring, and community building.
