Overview

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.

What You’ll Do

• Lead the design and delivery of high-quality, performant front-end applications using React and TypeScript.
• Own and modernise our UI architecture to accelerate product delivery without compromising quality.
• 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.

What We’re Looking For

• 5+ years’ experience in software engineering, with advanced expertise in React and TypeScript.
• 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.
