Job description

Overview

Senior Frontend Developer | Fareham

Up to £75k Plus Package | Fast-Growth Tech Scale-Up | High Ownership Role

I’m supporting a rapidly scaling technology business that’s building innovative, globally distributed digital products- and they’re now looking for a Senior Frontend Developer to take full ownership of their web UI and lead a major modernisation of their frontend architecture.

This is an on-site role based in a newly refurbished, award-winning workspace in Fareham, Hampshire, joining a collaborative, open, and fast-paced environment where engineering has a direct and visible impact on product direction.

The Opportunity

You’ll be the technical lead for the frontend- guiding the transition from a vanilla TypeScript / SASS setup to a modern framework such as React, Vue, or Svelte . This is a chance to shape best practices, introduce new tooling, and own the future of the frontend codebase.

If you enjoy architecting great user experiences, influencing technical decisions, and building elegant, scalable interfaces, this one is for you.

What You’ll Be Doing

• Leading the rewrite of the frontend using a modern JavaScript framework
• Designing clean, reusable, scalable UI components
• Collaborating closely with backend engineers (Python / Django) on API integrations
• Maintaining and improving existing TypeScript / SASS code during the transition
• Ensuring performance, accessibility, and reliability across the app
• Contributing to architecture discussions, design reviews, and technical planning
• Implementing robust testing across the frontend stack

What We’re Looking For

• Strong experience building modern frontend applications with TypeScript
• Expertise in React, Vue, Svelte, or a similar modern JS framework
• Deep understanding of HTML5, CSS3 / SASS, responsive design, and UI best practices
• Experience integrating with REST APIs
• Familiarity with testing frameworks (Jest, Vitest, Cypress, etc.)
• Knowledge of modern build tools (Vite, Webpack, etc.)

Nice-to-have

• Exposure to Django-based systems
• Experience with CI / CD for frontend workflows
• Understanding of Dockerised development
• Strong UX / UI sensibility

Why This Role Stands Out

• Huge influence on frontend architecture and technology choices
• A genuinely collaborative engineering culture
• High autonomy and ownership over the product’s direction
• Strong investment and a clear, exciting roadmap
• Competitive package + great environment + career progression
