About the Product
GRG Health’s have an in-house HCP engagement and research platform that manages respondent onboarding, survey execution, incentive payouts, and campaign
communication across global studies. We are now developing its version 2.0 — an AI-driven, community-based platform that adds HCP forums, CME modules, intelligent respondent targeting, recruiter
automation, and productivity tools like chatbots and journals, along with a mobile app for real-time engagement.

Built on NodeJS, ReactJS, and MongoDB (hosted on AWS), 2.0 will be developed and
scaled entirely by our internal engineering team.

• Develop REST and GraphǪL APIs for new modules (community, CME, AI
integration).
• Maintain and refactor existing NodeJS services to improve performance and
modularity.
• Integrate third-party tools (face recognition, payment, SMS/email, AI endpoints).
• Implement job queues, caching, and API rate limiting.
• Write unit/integration tests and maintain documentation.

• NodeJS (Express / NestJS), MongoDB, Redis, AWS (Lambda/ECS).
• Familiar with Python/FastAPI integration for AI microservices.
• Experience in building scalable, secure, multi-tenant architectures.

• Startup background preferred — “builder mindset.”
• Hands-on coding ability is non-negotiable for all roles.
• Strong ownership and ability to work in lean teams.
• Communication clarity and delivery focus > theoretical credentials.
