• Handle complex native features such as camera/eKYC, NFC, push notifications (Firebase), contacts, permissions, keychain, and deep links
• Integrate analytics and monitoring tools including Segment, CleverTap, Sentry, and Firebase Performance
• Work with custom native modules when required (e.g. FPT eKYC SDK)

3. Data & API

• Work extensively with GraphQL + Apollo Client: queries, mutations, subscriptions, and caching
• Run Apollo codegen to generate TypeScript types from GraphQL schemas
• Integrate REST APIs and SSE (Server-Sent Events) for real-time features

4. Technical Ownership

• Participate in technical decisions including library selection, coding conventions, and client-side architecture reviews
• Integrate third-party services such as Slack API, Jira API, and internal HR/HRM platforms
• Work on AI/LLM-powered features such as chatbot UI and streaming responses

Requirements

Must-have

• 2–4 years of hands-on experience with React and TypeScript
• At least 1 year of experience with React Native CLI, including shipping apps to both the Apple App Store and Google Play

General Qualifications

• Ability to work independently, estimate tasks, and deliver on schedule
