Senior React Native Developer

Brief DescriptionExperience: 5–10 years (minimum 3+ years deep React Native production experience) About the Opportunity DeviceDriven is leading a major digital transformation initiative, modernizing a global-scale transaction and engagement platform that processes millions of secure, real-time operations. As a Senior React Native Developer, you will build high-performance, secure, and scalable mobile applications used by consumers and enterprise customers globally. You will work closely with backend, cloud, and AI engineering teams to deliver a seamless mobile experience. If you have strong React Native fundamentals, production experience delivering multiple apps end-to-end, and optionally full-stack Node.js skills — this is a high-impact role where you’ll contribute directly to core fintech flows. Role Overview We are seeking a deeply experienced Senior React Native Engineer capable of building high-quality, performant mobile apps with secure authentication, real-time updates, complex state management, rich UI/UX, and robust API integrations. Full-stack experience with Node.js is a strong plus — especially for engineers comfortable working across mobile, backend services, and cloud APIs. You will collaborate with architects, backend teams, AI engineers, product owners, and other mobile developers in a fast-paced, engineering-centric environment. Key Responsibilities React Native Mobile Engineering

Build secure, scalable mobile apps using React Native (iOS + Android).

Own end-to-end screens, flows, and components — from architecture to deployment.

Implement complex features such as:

Secure login, multi-factor authentication (OAuth2, SAML, OpenID).

Real-time updates (WebSockets, push notifications).

Offline capabilities and background sync.

Deep linking, in-app routing, navigation patterns.

Work with native modules (Swift/Objective-C, Kotlin/Java) when required.

Architecture & State Management

Use modern state management (Redux Toolkit, MobX, Recoil, Zustand).

Implement modular, scalable architecture patterns (Clean Architecture, MVVM, etc.).

Optimize for performance, memory efficiency, rendering, and usable frame rates.

API Integration & Back-End Collaboration

Integrate with complex backend APIs, event-driven systems, and microservices.

Work closely with Node.js, DevOps, AI engineers, and cloud teams.

Consume secure REST/GraphQL APIs with attention to caching, retry logic, and error handling.

Full-Stack Node.js Development (Preferred)

Build backend microservices using Node.js + TypeScript.

Work with SQL (Postgres/MySQL) and NoSQL (MongoDB/DynamoDB).

Implement real-time services (WebSockets, message queues).

Collaborate with backend teams on API contracts, data formats, and performance.

Cloud, DevOps & Deployment Collaboration

Work with CI/CD pipelines for React Native (Fastlane, Bitrise, App Center, EAS).

Deploy apps to App Store and Google Play Store.

Collaborate with DevOps on AWS/GCP workloads when full-stack.

Work with API gateways, secure token handling, and user session flows.

Testing & Quality

Write comprehensive automated tests (unit, integration, e2e) using Jest, Detox, Cypress, or equivalent tools.

Participate in code reviews, pair programming, and continuous improvement of standards.

UI/UX Collaboration

Work with designers to translate Figma/specs into pixel-perfect UI.

Optimize for animations, gestures, accessibility, responsive layouts, and user experience.
