We’re partnering with a leading UK retail and digital platform business undergoing significant transformation, building out a modern, scalable engineering ecosystem across multiple brands and platforms.

They’re looking for a Senior Frontend Engineer to join a product-aligned, agile engineering team, playing a key role in shaping customer-facing experiences at scale.

This is a senior individual contributor position with real ownership, influence, and the opportunity to impact technical direction across a large, complex digital estate.

The Role

You’ll be working on a modern MACH-based architecture (Microservices, API-first, Cloud-native, Headless), helping deliver and evolve platforms that support 70+ websites and mobile applications.

Alongside delivery, you’ll act as a technical leader within the frontend community, mentoring engineers and driving best practices across teams.

What You’ll Be Doing

• Driving frontend architecture decisions (component design, state management, app structure)

• Building high-quality solutions using React, Next.js and TypeScript

• Influencing shared design systems and frontend standards

• Partnering closely with Product, Design and Content teams

• Owning critical customer journeys with a focus on performance, accessibility and usability

• Working with GraphQL and REST APIs, with some Node.js exposure

• Mentoring engineers and elevating overall engineering standards

• Identifying improvements across performance, CI/CD and developer experience

What They’re Looking For

• Strong experience as a Senior Frontend or Full-Stack Engineer in production environments

• Deep expertise in JavaScript, TypeScript, React and Next.js

• Experience mentoring and supporting engineers

• Strong understanding of performance, accessibility (WCAG) and responsive design

• Experience across the full SDLC including testing, CI/CD and automation

Nice to have:

• Experience with MACH/composable architecture

• Knowledge of Core Web Vitals

• Exposure to cloud platforms (Azure etc.) and Infrastructure as Code

• Experience in distributed or event-driven systems

Why Join?

This is an opportunity to join a high-growth, tech-driven environment where engineering plays a central role in shaping the future of a major digital platform. You’ll have real ownership, autonomy, and the chance to influence how things are built at scale.
