Job Description:
We're looking for a Senior Lead Engineer - React Native with deep experience designing and building scalable, high-performance mobile applications using React Native, TypeScript, Expo, and modern mobile architecture patterns. This role will play a critical part in shaping the technical direction of our mobile platform, driving architecture decisions, optimizing performance, and delivering enterprise-grade mobile experiences.

### What You’ll Be Doing

- Provide technical leadership and oversee the daily mobile engineering operations.

- Define and drive the mobile architecture strategy aligned with business goals.

- Lead the design and development of scalable, high-performance mobile applications using React Native and TypeScript.

- Architect modular, reusable component systems and scalable state management solutions (Redux, Zustand, Context API, etc.).

- Design clean navigation, deep linking, and mobile routing strategies (React Navigation, Expo Router).

- Implement secure authentication flows (OAuth/OIDC, biometrics, secure storage, token lifecycle management).

- Drive native module integrations (Swift, Kotlin) for SDKs such as payments, fraud detection, analytics, push notifications, and device security.

- Optimize mobile performance (startup time, bundle size, memory usage, rendering performance, offline caching).

- Establish CI/CD pipelines for mobile (Fastlane, EAS Build, App Store Connect, Google Play Console).

- Lead app release management, versioning strategy, and store compliance.

- Ensure adherence to mobile security best practices, privacy compliance, and accessibility standards.

- Partner with backend teams to define API contracts and optimize mobile-backend interactions.

- Champion automated testing (Jest, React Native Testing Library, Detox) and code quality standards.

- Mentor engineers and foster a culture of ownership, craftsmanship, and continuous improvement.

- Participate in architecture reviews and roadmap planning for long-term mobile platform scalability.

### What You Bring to the Table

- Strong hands-on experience building production-grade apps using React Native and TypeScript.

- Deep understanding of Expo ecosystem (EAS, OTA updates, build pipelines, native configuration).

- Expertise in mobile architecture patterns (Clean Architecture, MVVM, modular architecture).

- Experience integrating native iOS (Swift) and Android (Kotlin) modules into React Native apps.

- Strong understanding of app lifecycle, memory management, threading, and performance tuning.

- Experience implementing push notifications, deep linking, analytics SDKs, and mobile security frameworks.

- Familiarity with authentication flows (OIDC, PKCE, secure token handling).
- Experience with API integrations (REST, GraphQL) and handling network resiliency/offline-first design.

- Strong understanding of mobile DevOps, CI/CD, and release governance.

- Experience collaborating in Agile environments and influencing cross-functional stakeholders.

- Ability to balance hands-on development with strategic architectural leadership.

### Basic Qualifications

- Bachelor’s or Master’s degree in Computer Science, Engineering, or related field (or equivalent experience).

- 10+ years of software development experience.

- 6+ years of hands-on mobile development experience.

- 4+ years leading React Native applications in production environments.

- Proven experience delivering apps to both Apple App Store and Google Play Store.

- Experience working with cloud-based backends (Azure, AWS, or GCP).

- Strong experience with CI/CD pipelines, automated testing, and DevOps best practices.

- Demonstrated leadership experience mentoring engineers and guiding technical direction.

- Strong problem-solving skills with the ability to make strategic architectural decisions balancing business and technical needs.
