The Role

We're seeking a Senior Frontend Engineer who combines technical excellence with a sharp eye for detail and a passion for delivering beautiful, pixel‑perfect user interfaces. In this role, you'll play a critical part in shaping the user experience of our product by transforming high‑fidelity designs into seamless, responsive, and accessible web applications using React and Next.js. You’ll work closely with our product and design teams to shape the architecture of our frontend systems.

Key Responsibilities

  • Develop, maintain, and optimise high‑quality, responsive, and performant web applications using React and Next.js, ensuring a consistent experience across devices and browsers.
  • Collaborate closely with product designers to translate Figma mock‑ups into seamless, visually polished interfaces that meet both aesthetic and functional requirements.
  • Write clean, maintainable, and efficient code adhering to modern development standards, accessibility guidelines, and industry best practices.
  • Contribute to frontend architecture — defining scalable patterns, reusable components, and maintainable structures to support long‑term product growth.
  • Participate in code reviews and technical discussions, sharing knowledge and upholding code quality and consistency across the engineering team.
  • Continuously improve application performance through profiling, optimisation, and modern tooling and techniques.
  • Stay current with the latest trends and advancements in frontend development, particularly within the React / Next.js ecosystem.

What We Are Looking For

  • 10+ years building modern web applications, with deep production expertise in React and Next.js.
  • Expert‑level JavaScript and TypeScript, plus strong HTML and CSS — including responsive layouts, accessibility, and cross‑browser compatibility.
  • In‑depth experience with Payload CMS.
  • Proven ability to translate Figma designs into pixel‑perfect, maintainable frontend code.
  • Experience with analytics, A/B testing, and data‑driven methods to understand user behaviour and inform feature development.
  • Solid understanding of frontend performance — able to identify bottlenecks and implement effective solutions.
  • Proactive, self‑driven, and highly accountable — you take initiative, follow through, and hold yourself to a high standard.
  • Grit and drive — comfortable diving into complex problems, experimenting, and iterating to find the best solution.
  • Collaborative team player who thrives in a fast‑paced, high‑growth environment.

What We Offer

  • £80-90k and comprehensive benefits package.
  • Hybrid working model.
  • Real opportunities for progression as the business scales.
  • The chance to influence both customer experience and product development.
  • A culture that values ownership, impact, and continuous learning.
