Role Description As a Senior Front-End Developer your main responsibilities will involve: - UX & Product Design - Translate complex GenAI flows into simple, elegant journeys. - Own the design system: typography, colour, motion. - Prototype quickly and validate with real users. - Front-End Engineering - Ship production-grade React (TypeScript) every sprint. - Architect component libraries, state management (Redux-Toolkit / Zustand), server-side rendering, and micro-front-ends. - Fast-track code and prototyping with AI Agents. - Backend Integration - Design and consume REST / GraphQL APIs, WebSockets, and event streams. - Contribute lightweight backend services in Node.js / Express / Nest when needed (e.g., BFF pattern, feature toggles, edge functions). - Dev Ops & Quality - Automate builds, tests, and deployments via GitHub Actions / Azure DevOps. - Instrument monitoring (OpenTelemetry, Datadog) and feature flags for safe releases. - Leadership & Mentoring - Lead a squad of engineers and UX designers through weekly sprints. - Conduct design and code reviews, coach junior devs, evangelise front-end best practices. Qualifications - Strong experience building modern web apps in React + TypeScript. - Proven experience launching in production webapps with outstanding UX and performance. - Solid grounding in design thinking, information architecture, and interaction design (Figma, Storybook, Design Tokens). - Fluency in HTML5 / CSS3, Tailwind CSS or CSS-in-JS. - Backend chops: Node.js, API design, authentication (OAuth 2.0), basic DB skills (PostgreSQL / MongoDB) and cloud deployment (AWS / Azure). - Production know-how: observability, feature flags, A/B tests, error budgets. - Track record of sticky retention—you grow products over years, not hop projects every 12 months. - Clear, concise communicator who loves turning complexity into clarity.

• Develop and maintain scalable user-facing features utilizing React, TypeScript/JavaScript, HTML5, and CSS3. • Design, build, and optimize reusable component-based architectures. • Bridge the gap between graphical design and technical implementation. • Ensure all applications are fully responsive and adhere to accessibility standards. • Architect and develop data-heavy user interfaces. • Participate actively in Agile ceremonies, collaborating with cross-functional teams.
