Senior Mobile Engineers (React Native)

FHIR backend

If you are a builder who thrives on technical challenges and wants to create impactful mobile solutions that improve lives, we&aposd 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&aposs 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:
