About the Role
We are looking for a Senior UI/UX Developer who bridges the gap between design and engineering. You will not just write code; you will protect design fidelity, optimise performance, and build scalable front-end systems that our clients rely on every day.
Working closely with designers, product managers, and engineers, you will translate designs into pixel-perfect, accessible, and performant React interfaces — and set the standard for how our front-end is architected, reviewed, and maintained. This is a hands-on senior role with real influence over UI architecture, design-system direction, and the growth of the engineers around you.
Key Responsibilities
Design-to-code delivery — Translate Figma, Adobe XD, or Sketch designs into pixel-perfect, responsive React interfaces, preserving visual continuity and micro-interactions.
Component architecture — Build, version, and maintain reusable, well-documented component libraries and design systems that scale across client products.
Performance engineering — Diagnose and resolve slow renders using React DevTools, code-splitting,



memoization, and contemporary rendering patterns.
Accessibility — Ship inclusive software that meets WCAG 2.1/2.2 standards through semantic HTML and correct ARIA usage.
State & data flow — Model complex client-side state cleanly with Redux Toolkit, Zustand, or Recoil, and integrate RESTful and other APIs.
Quality & testing — Write and maintain tests with Jest, React Testing Library, and Playwright, and uphold quality through thorough code reviews.
Design–engineering partnership — Streamline handoffs between creative and engineering teams, advocating for the user and challenging complex flows to reduce friction.
Mentorship — Coach junior engineers on clean coding patterns, UI architecture, and review practices, raising the bar for the whole team.
Technical Qualifications
Experience — Generally 5 to 8+ years in front-end engineering, with at least 2 years in a senior or lead role.
