Experience Required
Front-end mastery – you bring 6+ years of software engineering with deep expertise in modern front-end frameworks (React, Next.js, Sitecore or Angular), TypeScript/JavaScript (ES6+), HTML5 and CSS3, and you build scalable, testable, component-driven interfaces.
Design-to-code craftsmanship – you translate Figma designs into pixel-accurate, responsive UIs, work fluently with design systems and component libraries, and care deeply about micro-interactions, motion and visual polish.
Full-stack versatility – while your depth is on the front end, you are comfortable integrating with REST/GraphQL APIs and can contribute across the stack (Node.js, Python or Java) when the work demands it.
Performance & accessibility focus – you optimise for Core Web Vitals, bundle size, rendering performance and cross-browser behaviour, and you build inclusive, accessible experiences that meet WCAG standards.
A bias for rapid prototyping – you turn a loosely defined problem into a working, interactive prototype in days, and let real user feedback rather than a perfect spec drive each iteration.
Modern testing & tooling – you work hands-on across the SDLC with unit, component and end-to-end testing (Jest, React Testing Library, Playwright or Cypress) and modern build tooling (Vite, Webpack, CI/CD).
An AI-led approach to building – you reach for AI coding assistants and agentic tooling by default to move faster, and can build the guardrails that make front-end delivery reliable and consistent.
Hands-on cloud experience – you have deployed front-end applications on AWS, GCP or Azure (CDNs, edge, serverless) and pick up new cloud services quickly as the work demands.
A client-facing mindset – you work embedded alongside client teams, translate business problems into experience solutions, and explain trade-offs clearly to engineers and non-technical stakeholders alike.
Set Yourself Apart With
Strong, innovative and initiative-seeking approach to problem solving and finding solutions.
Flexible and proactive/self-motivated working style with strong personal ownership of problem resolution.
Strong communication skills with sound articulation and comprehension.
