Full Stack JS Engineer

This position contributes to the development of a large-scale digital product designed to support students in building career-ready skills and accessing employment opportunities. At the same time, the platform enables organisations to connect with emerging talent in a more effective and targeted way.

You'll be involved in shaping a modern, customer-facing web application that serves a substantial user base, working closely with product, design, and engineering colleagues.

Why you'll enjoy it here

Technology sits at the heart of what we do. Our teams build tools that benefit learners, educators, and employers alike.

You'll join a growing engineering function working on a modern, service-oriented platform. The environment is collaborative, forward-thinking, and encourages experimentation, learning, and continuous improvement. Engineers are trusted to influence decisions and help evolve both the product and the technical foundations behind it.

Who this role is for

This opportunity suits a JavaScript-focused software engineer with solid experience across the full stack. You should be comfortable working with modern front-end frameworks, server-side JavaScript, and APIs, and enjoy collaborating within autonomous, Agile teams.

A curiosity for clean design, scalable systems, and well-tested code will be key to succeeding in this role.
