We’re seeking a Senior / Principal UI Developer to lead the evolution of our front-end platforms and elevate the quality of digital experiences within a healthcare technology environment. This role is ideal for someone who blends deep React and TypeScript expertise with strong design sensibility, engineering leadership, and a genuine enthusiasm for AI-driven development.
You’ll shape scalable UI architecture, champion best practices, and help embed AI-enabled workflows into everyday engineering.

Collaborate closely with engineers, product leaders, and QA in a high-performing Agile team.
Champion usability, accessibility, and clean design across all user interfaces.
Define and uphold engineering standards, design principles, and front-end best practices.
Build and refine AI-assisted workflows (prompt design, automation pipelines, agentic tooling) to streamline development tasks—from documentation to large-scale refactoring.
Drive adoption of robust testing practices and CI/CD automation.
Mentor team members and contribute to growing full-stack capability across the team.
Ensure secure development practices are embedded in all solutions.
Stay ahead of emerging technologies and share knowledge across the organisation.

Strong foundation in software architecture, design principles, and clean coding standards.
Proven experience designing intuitive, elegant user interfaces (typography, layout systems, interaction patterns).
Deep understanding of UX best practices and responsive design across browsers.
Hands‑on experience integrating REST APIs (experience building APIs is advantageous).
Experience with modern testing frameworks (Jest or Vitest; React Testing Library a plus).
Strong CSS knowledge including SASS and CSS‑in‑JS solutions (e.g., styled‑components, emotion).
Experience with modern build tools (Vite or similar), NPM ecosystem, and modular component design.
Exposure to automated deployments and CI/CD pipelines.
Experience leveraging AI tools, agentic orchestration, or MCP‑based systems in software development is highly desirable.
Degree in Computer Science, Engineering, or related discipline (or equivalent experience).
What Sets You Apart
Passion for AI and its practical application in software engineering.
A design‑first mindset with an eye for detail.
Technical leadership without ego—leading through example and quality.
A drive to continuously improve systems, processes, and people.
