Job Description:

We are seeking exceptional Senior Mobile Engineers (React Native) to join our fast-paced and innovative health tech team.

This is a unique opportunity to lead a fundamental shift in our mobile strategy as we transition to a unified React Native platform.

You will be instrumental in building a new, offline-first application from the ground up, working alongside our existing native Android and iOS teams.

The role requires a deep understanding of mobile architecture, a passion for solving complex data challenges, and a commitment to creating a secure and seamless user experience.

The ideal candidates will be seasoned mobile developers with extensive experience in React Native and a strong portfolio of published applications.

You must have a solid understanding of a FHIR backend , leveraging GraphQL and RESTful APIs , and be prepared to tackle the complexities of an offline-first paradigm to store critical patient data securely on-device.

This role demands a high degree of technical leadership, architectural vision, and a collaborative mindset to mentor others and drive the project to success.

If you are a builder who thrives on technical challenges and wants to create impactful mobile solutions that improve lives, we'd love to have you on board.

Responsibilities:

Offline-First & Data Architecture:

• Design and implement a robust offline-first data layer for the new React Native application.
  
  
• Architect and build a resilient synchronization engine to handle bidirectional data flow between the device and our FHIR backend, implementing a hybrid push-pull model.
  
  
• Define and implement an intelligent merge-based conflict resolution strategy to prevent data loss in a high-stakes, disconnected environment.
  
  
• Manage local data storage, including large binary files (e.g., medical images, documents) on the device's file system, ensuring efficient access and a dual storage approach.
  
  

React Native Development & Leadership:

• Lead the design, development, and maintenance of a high-quality, scalable, and secure React Native application from scratch.
  
  
• Define and implement scalable component architecture and state management strategy.
  
  
• Conduct thorough code reviews to ensure high standards of code quality, security, and performance.
  
  
• Act as a technical mentor for junior engineers, fostering a culture of continuous learning and excellence.
  
  
• Collaborate closely with our native Android and iOS teams to ensure seamless functionality and knowledge transfer.
  
  

API Integration & Health Tech Domain:

• Integrate a GraphQL API alongside RESTful APIs to deliver efficient and dynamic data handling from our FHIR backend.
  
  
• Implement FHIR-compliant solutions for seamless interoperability with healthcare systems.
  
  
• Architect and implement real-time, event-driven features using Pub/Sub patterns and WebSocket principles.
  
  

Security & Compliance:

• Enforce a security-first, privacy-by-design mindset throughout the development lifecycle.
  
  
• Implement robust on-device security measures, including hardware-backed key management and AES-256 encryption , to protect sensitive Protected Health Information (PHI) and ensure compliance with regulations like HIPAA, GDPR, and DPDP .
  
  

Innovation & Continuous Improvement:

• Leverage AI-assisted coding tools to accelerate development while maintaining a strong sense of critical thinking and code ownership.
  
  
• Stay up-to-date with the latest trends in React Native, mobile architecture, and health tech to ensure our application remains at the cutting edge.
  
  
• Proactively address technical debt and enhance the scalability and maintainability of the codebase.
  
  

Qualifications:

• Experience: Minimum 5-7 years of professional experience in mobile application development , with at least 2 years in a senior capacity using React Native .
  
  
• Programming Languages: Expertise in JavaScript/TypeScript.
  
  
• Mobile Ecosystem: Deep knowledge of the React Native ecosystem, including component lifecycles, state management libraries (e.g., Redux, Zustand), and navigation.
  
  
• Offline-First: Proven experience in designing and implementing robust offline-first applications with complex data synchronization and conflict resolution.
  
  
• API Expertise: Strong understanding of GraphQL and experience integrating GraphQL and RESTful APIs, particularly in a health tech or similar domain.
  
  
• Data Security: A strong understanding of mobile security best practices, including encryption, secure data storage, and compliance standards (e.g., HIPAA).
  
  
• CI/CD: Familiarity with continuous integration and deployment pipelines for mobile apps.
  
  
• Problem-Solving: Exceptional analytical and debugging skills with a proactive, solution-oriented approach.
  
  
• Leadership: A strong ability to lead projects, mentor junior developers, and drive architectural decisions.
  
  
• Communication: Excellent verbal and written communication skills for effective collaboration with cross-functional teams.
  
  
• Ownership: A high degree of ownership and accountability for the quality, security, and performance of the product.
  
  
• Prior experience in Native Android (Kotlin) or iOS (Swift) development.
  
  
• Experience in healthtech or another highly regulated industry.
  
  
• A portfolio of published applications that demonstrate an understanding of complex data and security challenges.
  
  
• Familiarity with FHIR (Fast Healthcare Interoperability Resources) standards.
  
  
• Knowledge of specific tools like Firebase, Sentry, or other mobile observability platforms.
  
  
• Experience with multi-module app structures and large-scale mobile application architecture.
