Senior Front - End Developer (React / Next.js)

E-Merge IT Recruitment

We’re looking for a Front-End Developer who is comfortable working in an existing production codebase and can build safe, usable interfaces in a clinically sensitive environment.

This role is focused on clarity, stability, and thoughtful implementation rather than flashy UI work.

Key Technical Skills

  • Strong experience with React and TypeScript
  • Strong experience building applications with Next.js
  • Good understanding of component architecture and state management
  • Experience consuming and normalizing complex API responses
  • Strong CSS and Tailwind CSS skills
  • Experience building responsive application interfaces
  • Comfortable debugging browser, network, and server-side rendering issues
  • Familiarity with Git workflows
  • Comfortable working with local development servers and Docker-backed APIs
  • Clear communication around assumptions, blockers, and trade-offs

The project currently uses

  • Next.js
  • React
  • TypeScript
  • Tailwind CSS
  • Local API proxying to orchestration services
  • Docker-based backend services
  • FHIR-derived JSON payloads

The ideal developer

  • Reads and understands the existing code before making changes
  • Keeps UI changes scoped, intentional, and maintainable
  • Preserves important clinical context instead of over-simplifying interfaces
  • Avoids decorative UI patterns that obscure important information
  • Values clarity and usability over visual noise
  • Can identify missing, duplicated, or incorrectly shaped data
  • Collaborates effectively with backend developers
  • Uses TypeScript types as enforceable contracts, not decoration
  • Tests critical data transformations and rendering assumptions
  • Can translate vague product requirements into safe, practical interfaces
