- Monitor and optimize app performance, stability, battery usage, and telemetry; troubleshoot production issues.
- Ensure compliance with enterprise security, data privacy, and secure coding practices.
- Contribute to agile ceremonies (planning, refinement, stand-ups) and deliver iteratively with the team.
Skills Required (Experience and Capabilities):
- 3+ years’ experience building mobile apps for both iOS and Android, using native and/or cross-platform approaches.
- Native: Swift/SwiftUI (iOS), Kotlin/Jetpack (Android)
- Cross-platform (nice to have): Angular
- Strong understanding of mobile app architecture, design patterns, performance optimization, and debugging.

- Working knowledge of .NET backend development and API fundamentals (able to collaborate effectively and contribute where needed).
- Familiarity with GCP-hosted services and mobile-relevant cloud components (e.g., Firebase, Cloud Functions, Pub/Sub or equivalents).
- Experience with CI/CD and release tooling (e.g., GitHub Actions, Fastlane, Bitrise, Azure DevOps or similar).
- Understanding of security best practices for mobile (secure storage, certificate pinning awareness, threat modelling mindset).
- Strong communication skills and a collaborative approach across engineering, product, and design.
