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.
