Senior Fullstack Developer

London (Hybrid)

I'm working with a high-traffic digital platform that's hiring a Fullstack Developer to help build and evolve their in-house publishing and content systems. The company delivers content to hundreds of millions globally and prides itself on scale, performance, and innovation.

This is a great opportunity to join a collaborative, fast-paced engineering team working on everything from web platform architecture to high-volume APIs and machine learning integration.

What you'll be doing:

  • Building and maintaining scalable services using Node.js, React, and modern JavaScript frameworks.
  • Contributing to both front-end and back-end architecture - from UI design systems to content APIs.
  • Working with cross-functional teams to prototype, test, and deliver features across large-scale platforms.
  • Helping transition a legacy CMS system into a modular, React-driven application.
  • Participating in code reviews, performance tuning, and infrastructure discussions.
  • Getting involved in new projects spanning ad tech, machine learning, and real-time analytics.

What you'll bring:

  • Strong commercial experience with Node.js, React, and client-side JavaScript.
  • Solid understanding of modern web development (REST APIs, SSR, CI/CD, etc.).
  • Comfort working in a fast-moving environment, solving large-scale engineering problems.
  • A collaborative mindset - eager to learn and contribute in a supportive team.
  • Experience with tools like GitHub Actions, Docker, or cloud services (AWS/GCP) is a bonus.

If you're a curious and motivated fullstack developer looking to work at scale and ship meaningful features across global platforms, this could be a great step forward in your career.
